Arithmetic Questions and Answers

1. The total age of three kids in a family is 27 years. What will be the total of their ages after three years?

Total age of three kids = 27 years

After three years, the age of each kid will increase by 3.

So, the total age after three years = 27 + 3 × 3

Therefore, the total age of three kids after three years will be 36 years.

2. Find the product of all the numbers present on the calculator pad.

Numbers on the calculator pad = 0,1, 2, 3, 4, 5, 6, 7, 8, 9

Product of all these numbers = 0 × 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 = 0 {since the product of any number with 0 is also 0)

3. Jessi ran 12 laps every day for two weeks. How many laps did she run in all?

Number of laps ran by Jessi in a day = 12

Number of day = 2 weeks = 2 × 7 days = 14 days

Total laps run by Jessi in 2 weeks = 12 × 14 = 168

4. Simplify: 133 – 19 × 2 + 15

133 – 19 × 2 + 15

= 133 – 38 + 15

= 148 – 38

Therefore, 133 – 19 × 2 + 15 = 110.

5. Find the next term of the arithmetic sequence 177, 173, 169, 165,…

Given arithmetic sequence is:

177, 173, 169, 165,…

Here, 173 – 177 = -4

169 – 173 = -4

165 – 169 = -4

So, the next term = 165 – 4 = 161

6. Kamal’s annual income is Rs. 288000. His annual savings amount to Rs. 36000. What is his total yearly expenditure?

The annual income of Kamal = Rs. 288000

Annual savings = Rs. 36000

Total yearly expenditure of Kamal = Rs. 288000 – Rs. 36000 = Rs. 252000

7. Find the value of 45 ÷ 9 × 3 + 15 – 6

45 ÷ 9 × 3 + 15 – 6

= 5 × 3 + 15 – 6

= 15 + 15 – 6

= 30 – 6

Hence, the value of 45 ÷ 9 × 3 + 15 – 6 is 24.

8. Simplify the numerical expression: [36 ÷ (-9)] ÷ [(-24) ÷ 6]

[36 ÷ (-9)] ÷ [(-24) ÷ 6]

This can be written as:

= (36/-9) ÷ (-24/6)

= (-4) ÷ (-4)

Thus, [36 ÷ (-9)] ÷ [(-24) ÷ 6] = 1.

9. Find the missing number in the following: 7 – 24 ÷ 8 × m + 6 = 1

7 – 24 ÷ 8 × m + 6 = 1

7 – (24/8) × m + 6 = 1

7 – 3 × m + 6 = 1

13 – 3 × m = 1

⇒ 3 × m = 13 – 1

⇒ 3 × m = 12

Therefore, the missing number is 4.

10. Mehak bought 96 toys priced equally for Rs. 12960. The amount of Rs. 1015 is still left with him. Find the cost of each toy and the amount he had.

Number of toys Mehak bought = 96 toys

Cost of 96 toys = 12960

Cost of one toy = 12960/96 = 135

Amount left with him = 1015

Amount he gave = 12960

Amount he had initially = 12960 + 1015 = 13975

Thus, the cost of each toy was Rs. 135, and he had the amount of Rs. 13975.

In order to access this I need to be confident with:

Here you will learn about arithmetic, including key terminology and mathematical symbols, using the four operations with positive and negative integers, and inverse operations.

Students will first learn about arithmetic as part of number and operations in 4th and 5th grade and continue to build on this knowledge in the number system in 6th and 7th grade.

What is arithmetic?

Arithmetic is the study of numbers and the operations between them. It is an elementary branch of mathematics.

The definition of arithmetic comes from the Greek word “arithmos”, meaning number, or the art of counting.

To solve problems using basic arithmetic, you need to understand and use the four operations.

The four operations you will be using are: addition , subtraction , multiplication, and division .

Arithmetic with four operations

Below is a table showing the four operations of arithmetic with their associated symbols.

Each operation has a different function that you should be confident with using.

Addition is the operation of combining two or more numbers together.

The two numbers can be represented by a and b, and c will represent the sum of a and b.

This would be written as a+b=c and pronounced a plus b is equal to c.

US Arithmetic image 2

Addition is commutative, which means that the order in which addition is carried out does not matter.

For example,

Addition can be done with positive and negative integers, fractions, and decimals.

Addition represents a movement up the number line. Here are some examples:

US Arithmetic image 3

In order to solve addition problems with larger numbers, you can use the standard algorithm.

For example, 347+21 :

US Arithmetic image 4

It is important to consider the place value of each digit and line up the corresponding digits in each number.

Subtraction

Subtraction is the operation of finding the difference between two numbers.

The number remaining when the number b is subtracted from the number c would equal a, or the answer to a subtraction problem.

This would be written as c-b=a and pronounced c take away b is equal to a.

US Arithmetic image 5

Subtraction is not commutative. If the order of the numbers within the calculation changes, the result will change.

Subtraction can also be done with positive and negative integers, fractions, and decimals. Subtraction represents a movement down the number line. Here are some examples:

US Arithmetic image 6

In order to solve subtraction problems with larger numbers, you can use the standard algorithm.

US Arithmetic image 7

It is important to consider the place value of each digit and line up the corresponding digits and decimal place in each number.

Multiplication

Multiplication is essentially repeated addition.

If you have n copies of a, you multiply a by n to find how many are in the new set, m.

This is the same as calculating a+a+a+… \, n times.

This would be written as n\times{a}=m and pronounced n times a is equal to m.

arithmetic problem solving questions

The product is the answer you get when multiplying one number by another. The multiplicand is the quantity to be multiplied by the multiplier, which will give you a product.

multiplicand \times multiplier = product

arithmetic problem solving questions

In this calculation,

6 is the multiplicand , 3 is the multiplier and the answer, 18 is the product .

The product will be 0 if either the multiplicand or multiplier is 0.

Multiplication is commutative. The order in which the calculation is performed does not matter.

Multiplication can be done with positive and negative integers, fractions, and decimals. When multiplying positive and negative numbers, the following rules apply:

US Arithmetic image 10

To solve multiplication problems with larger numbers, you can use an area model.

US Arithmetic image 11

Division shares or breaks a number into equal sized numbers of groups.

If the number m can be shared equally between n groups, with no remainder, then this is written as m\div{n}=a and pronounced m divided by n is equal to a.

US Arithmetic image 12

The quotient is the answer you get when dividing one number by another.

The word quotient comes from Latin and means ‘how many times’. When dividing, you are finding out ‘how many times’ a number goes into another number.

dividend \div divisor = quotient

US Arithmetic image 13

8 is the dividend , 4 is the divisor and the answer, 2 is the quotient.

The quotient will only be 0 if the dividend is 0 but the divisor is not.

Unlike multiplication, division is not commutative. If the order of the numbers within the calculation changes, the result will change.

12\div{4} ≠ {4}\div{12}

Division can also be done with positive and negative integers, fractions, and decimals. When dividing positive and negative numbers, the following rules apply:

US Arithmetic image 14

To perform division problems with larger numbers, you can use long division.

US Arithmetic image 15

Inverse operations

Inverse operations reverse an operation that has been carried out. Below is a table outlining some operations along with their inverse operations.

Note that you can switch the columns so the inverse operation of subtraction is addition and the inverse operation of division is multiplication, etc.

Using the inverse operations helps us see relationships between numbers and are often referred to as fact families. Fact families show the relationship between the same set of numbers, just as inverse operations do.

How to use arithmetic with positive and negative numbers

In order to use arithmetic with positive and negative numbers:

Determine which operation you will use.

  • Perform the chosen operation .

Arithmetic examples

Example 1: addition with decimals.

Calculate the value of 10.9+34.3.

Here you will use addition.

2 Perform the chosen operation.

Using the standard algorithm, you have:

US Arithmetic example 1 image 1

Starting on the right, the tenths place, you add 9+3=12. The tenths column value of 2 is placed below the answer line, and the 1 is carried above the addition problem, so that you can add it to the next column total (the units column).

US Arithmetic example 1 image 2

Adding 0, 4, and the 1 that was carried from the tenths column, you have 0+4+1=5 and so 5 goes into the answer bar for the units column.

US Arithmetic example 1 image 3

The final column requires us to add 1 and 3, \, 1+3=4 and so you put a 4 in the tens column.

US Arithmetic example 1 image 4

So 10.9+34.3=45.2.

Example 2: subtraction (word problem)

96 mathematicians attended a celebration party at a hotel. 38 mathematicians stayed overnight. How many mathematicians did not stay overnight?

Here you will use subtraction. You need to solve 96-38.

Perform the chosen operation.

Writing subtraction using the standard algorithm, you have:

US Arithmetic example 2 image 1

Starting from the units column, 6-8 is a negative number, so you have to borrow from the tens column.

US Arithmetic example 2 image 2

16-8=8 and so the value for the units column is 8.

US Arithmetic example 2 image 3

Continuing with the tens column, you have 8-3=5.

US Arithmetic example 2 image 4

58 guests did not stay overnight.

Example 3: multiplication (word problem)

A sack can hold 36 potatoes. A farmer packs 24 sacks of potatoes with no leftover potatoes. How many potatoes does the farmer pack?

As there are 36 potatoes per sack and 24 sacks, you will multiply these values.

Using the area model, you have:

US Arithmetic example 3 image 1

By multiplying each row value by each column value, you get:

US Arithmetic example 3 image 2

Adding the new values in the area model, you have:

US Arithmetic example 3 image 3

The farmer packs 864 potatoes.

Example 4: division (word problem)

A bar of chocolate is made up of 84 individual cubes. The bar is 6 cubes wide. How many rows does the chocolate bar have?

Each column contains 6 cubes and there are 84 cubes in total. You will need to divide 84 by 6 to determine the number of rows in the chocolate bar.

Using partial quotients, you have:

US Arithmetic example 4 image 1

You will think of a multiple of 6 that will get you as close to 84, without going over.

6 \times 10=60

US Arithmetic example 4 image 2

You will think of another multiple of 6 that will get you as close to 24 as possible, without going over.

\begin{aligned} & 6 \times 4=24 \\\\ & 24-24=0 \end{aligned}

arithmetic problem solving questions

You will add your two partial quotients together 10 + 4 = 14.

US Arithmetic example 4 image 4

The chocolate bar has 14 rows.

Example 5: addition, with negative numbers

Calculate (-3)+(-2).

Here, you are solving an addition problem with the two negative numbers.

+ and - together make a - therefore

-3+-2=-3-2=-5

Example 6: subtraction, with negative numbers

Calculate 5-(-3).

Here you will subtract -3 from 5.

Two - signs together make a + therefore

Example 7: multiplication, with negative numbers

Calculate 8\times(-2).

Here you will use multiplication.

8\times(-2)=-16.

Example 8: division, with negative numbers

Calculate \cfrac{-120}{-3}.

A fraction is the division of two quantities and so here you would use division. The numerator is known as the dividend and the denominator is known as the divisor. The result of division is called a quotient.

Teaching tips for arithmetic

  • If a student is struggling with using algorithms with the given operation, they need more experience with concrete models.
  • When teaching students to use the algorithm for division, or long division, provide graph paper for students to use to keep their work neat and legible.
  • Be sure to practice a problem solving method when working with word problems. Students may be able to solve a given equation, but struggle when having to pull information out of and comprehend a word problem.
  • The use of a number line can be very impactful when working with positive and negative numbers.

Easy mistakes to make

  • Parentheses are not an arithmetic operation Operations allow us to perform calculations between two or more numbers. In the associative property, parentheses dictate the order in which this should be completed and so they are technically not an operation. However, parentheses are sometimes used in place of multiplication symbols, for example, 6(7-3).
  • Multiplying by \bf{0} by any number equals \bf{0} It is important to remember that multiplying anything by 0 gives the answer 0.
  • Multiplying, instead of dividing, when working with fractions Mistakes can easily be made when dividing fractions. When dividing a number by a fraction, a commonly seen error is that the value is multiplied by the fraction instead. For example, 12\div\frac{1}{2}=6 is incorrect. Instead, the correct answer is 12\div\frac{1}{2}=12\times{2}=24.
  • Knowing the value of decimal places are important It’s important that students remember the concept of place value when solving with decimals. Knowing the value of the numbers you are performing an operation with is crucial.

Continue this pattern until you have 7 multiples.

The answer is 63.

4. 120 high school students are divided into small research groups. If there are 20 groups, how many students are in each group?

You need to divide 120 by 20.

You can use mental math to find the solution to this division problem.

You can split the dividend, 120, into two parts that can be easily divided by 20.

Then using math facts, divide both parts by 20.

5. A New York hotel comprises 67 floors above ground and 4 floors below ground. A guest parks on floor -3, in the basement, and is staying on the 43 rd floor of the hotel. How many floors must he go up to get from his car to his hotel room?

You will subtract 43 and -3.

Two – signs together make a + therefore,

so 43- \, -3=43+3

The answer is 46 floors.

6. Anna buys a car for \$9,000. She pays a deposit of \$2,400 and pays the rest off in monthly installments of \$110 per month. How many months will Anna be paying for her car?

This is a two-step problem.

The first step requires subtraction to calculate the remaining amount to pay for the car.

The car was \$9,000 and Anna paid a deposit of \$2,400.

The second step will require division of the remaining amount, \$6,600 by 110, the payment Anna will make each month.

The answer is 60 months.

7. Calculate \cfrac{5}{6}+\cfrac{4}{7}.

First, you will need to find a common denominator between the two fractions. To do this, list the multiples of each number until you find one that both have in common.

US Arithmetic practice question 7 image 1

You will also need to fix the numerators by multiplying them by the same factor you multiplied the denominator by.

US Arithmetic practice question 7 image 2

Now that the denominators are the same, you can add the numerators together.

Arithmetic sequences, introduced in Section 8.1, have many applications in mathematics and everyday life. This section explores those applications.

Example 8.2.1

A water tank develops a leak. Each week, the tank loses \(5\) gallons of water due to the leak. Initially, the tank is full and contains \(1500\) gallons.

  • How many gallons are in the tank \(20\) weeks later?
  • How many weeks until the tank is half-full?
  • How many weeks until the tank is empty?

This problem can be viewed as either a linear function or as an arithmetic sequence. The table of values give us a few clues towards a formula.

clipboard_e5c7552a37ec3c13691ea706a3d499232.png

The problem allows us to begin the sequence at whatever \(n\)−value we wish. It’s most convenient to begin at \(n = 0\) and set \(a_0 = 1500\).

Therefore, \(a_n = −5n + 1500\)

Since the leak is first noticed in week one, \(20\) weeks after the initial week corresponds with \(n = 20\). Use the formula where \(\textcolor{red}{n = 20}\):

\(a_{20} = −5(\textcolor{red}{20}) + 1500 = −100 + 1500 = 1400\)

Therefore, \(20\) weeks later, the tank contains \(1400\) gallons of water.

  • How many weeks until the tank is half-full? A half-full tank would be \(750\) gallons. We need to find \(n\) when \(\textcolor{red}{a_n = 750}\).

\(\begin{array} &750 &= −5n + 1500 &\text{Substitute \(a_n = 750\) into the general term.} \\ 750 − 1500 &= −5n + 1505 − 1500 &\text{Subtract \(1500\) from each side of the equation.} \\ −750 &= −5n &\text{Simplify each side of the equation.} \\ \dfrac{−750}{−5} &= \dfrac{−5n}{−5} &\text{Divide both sides by \(−5\).} \\ 150 &= n & \end{array}\)

Since \(n\) is the week-number, this answer tells us that on week \(150\), the tank is half full. However, most people would better understand the answer if stated in the following way, “The tank is half full after 150 weeks.” This answer sounds more natural and is preferred.

  • How many weeks until the tank is empty? The tank is empty when \(a_n = 0\) gallons. Find \(n\) such that \(\textcolor{red}{a_n = 0}\).

\(\begin{array}& 0 &= −5n + 1500 &\text{Substitute \(a_n=0\) into the general term.} \\ 0 − 1500 &= −5n + 1500 − 1500 &\text{Subtract \(1500\) from each side of the equation.} \\ −1500 &= −5n &\text{Simplify.} \\ \dfrac{−1500}{−5} &= \dfrac{−5n}{−5} &\text{Divide both sides by \(−5\).} \\ 300 &= n & \end{array}\)

Since \(n\) is the week-number, this answer tells us that on week \(300\), the tank is empty. However, most people would better understand the answer if stated in the following way, “ The tank is empty after 300 weeks. ” This answer sounds more natural and is preferred.

Example 8.2.2

Three stages of a pattern are shown below, using matchsticks. Each stage requires a certain number of matchsticks. If we keep up the pattern…

  • How many matchsticks are required to make the figure in stage \(34\)?
  • What stage would require \(220\) matchsticks?

Let’s create a table of values. Let \(n =\) stage number, and let \(a_n =\) the number of matchsticks used in that stage. Then note the common difference.

clipboard_e25ba1d367972bd713a4ef5118c739484.png

Find the value \(a_0\):

\(\begin{array} &a_0 + 3 &= 4 \\ a_0 + 3 − 3 &= 4 − 3 \\ a_0 &= 1 \end{array}\)

The general term of the sequence is:

\(a_n = 3n + 1\)

  • Compute \(a_{34}\) to find the number of matchsticks in stage \(34\):

\(a_{34} = 3(\textcolor{red}{34}) + 1 = 103\).

There are \(103\) matchsticks in stage \(34\).

  • What stage would require \(220\) matchsticks? We are looking for the stage-number, given the number of matchsticks. Find \(n\) if \(a_n = 220\).

\(\begin{array} &220 &= 3n + 1 \\ 219 &= 3n \\ 73 &= n \end{array}\)

Answer Stage \(73\) would require \(220\) matchsticks.

Example 8.2.3

Cory buys \(5\) items at the grocery store with prices \(a_1\), \(a_2\), \(a_3\), \(a_4\), \(a_5\) which is an arithmetic sequence. The least expensive item is \($1.89\), while the total cost of the \(5\) items is \($12.95\). What is the cost of each item?

Put the \(5\) items in order of expense: least to most and left to right. Because it is an arithmetic sequence, each item is \(d\) more dollars than the previous item. Each item’s price can be written in terms of the price of the least expensive item, \(a_1\), and \(a_1 = $1.89\).

clipboard_e4455aea24708d7e0d8b83d55c771a802.png

The diagram above gives \(5\) expressions for the costs of the \(5\) items in terms of \(a_1\) and the common difference is \(d\).

\(\begin{array} &a_1 + a_2 + a_3 + a_4 + a_5 &= 12.95 &\text{Total cost of \(5\) items is \($12.95\).} \\ a_1 + (a_1 + d) + (a_1 + 2d) + (a_1 + 3d) + (a_1 + 4d) &= 12.95 &\text{See diagram for substitutions.} \\ 5s_1 + 10d &= 12.95 &\text{Gather like terms.} \\ 5(1.89) + 10d &= 12.95 &a_1 = 1.89. \\ 9.45 + 10d &= 12.95 &\text{Simplify.} \\ 9.45 + 10d − 9.45 &= 12.95 − 9.45 &\text{Subtract \(9.45\) from each side of equation.} \\ 10d &= 3.50 &\text{Simplify. Then divide both sides by \(10\).} \\ d &= 0.35 &\text{The common difference is \($0.35\).} \end{array}\)

Now that we know the common difference, \(d = $0.35\), we can answer the question.

clipboard_e0e8f0221b97bd16399f771ecb8447115.png

The price of each item is as follows: \($1.89, $2.24, $2.59, $2.94, $3.29\).

1. ZKonnect cable company requires customers sign a \(2\)-year contract to use their services. The following describes the penalty for breaking contract: Your services are subject to a minimum term agreement of \(24\) months. If the contract is terminated before the end of the \(24\)-month contract, an early termination fee is assessed in the following manner: \($230\) termination fee is assessed if contract is terminated in the first \(30\) days of service. Thereafter, the termination fee decreases by \($10\) per month of contract.

How to easily make your own math word problems & word problems worksheets

Two teachers are discussing math with a pen and a notebook

Armed with 120 examples to spark ideas, making your own math word problems can engage your students and ensure alignment with lessons. Do:

  • Link to Student Interests:  By framing your word problems with student interests, you’ll likely grab attention. For example, if most of your class loves American football, a measurement problem could involve the throwing distance of a famous quarterback.
  • Make Questions Topical:  Writing a word problem that reflects current events or issues can engage students by giving them a clear, tangible way to apply their knowledge.
  • Include Student Names:  Naming a question’s characters after your students is an easy way make subject matter relatable, helping them work through the problem.
  • Be Explicit:  Repeating keywords distills the question, helping students focus on the core problem.
  • Test Reading Comprehension:  Flowery word choice and long sentences can hide a question’s key elements. Instead, use concise phrasing and grade-level vocabulary.
  • Focus on Similar Interests:  Framing too many questions with related interests -- such as football and basketball -- can alienate or disengage some students.
  • Feature Red Herrings:  Including unnecessary information introduces another problem-solving element, overwhelming many elementary students.

A key to differentiated instruction , word problems that students can relate to and contextualize will capture interest more than generic and abstract ones.

Final thoughts about math word problems

You’ll likely get the most out of this resource by using the problems as templates, slightly modifying them by applying the above tips. In doing so, they’ll be more relevant to -- and engaging for -- your students.

Regardless, having 120 curriculum-aligned math word problems at your fingertips should help you deliver skill-building challenges and thought-provoking assessments.

The result?

A greater understanding of how your students process content and demonstrate understanding, informing your ongoing teaching approach.

The resources on this page will hopefully help you teach AO2 and AO3 of the new GCSE specification - problem solving and reasoning.

This brief lesson is designed to lead students into thinking about how to solve mathematical problems. It features ideas of strategies to use, clear steps to follow and plenty of opportunities for discussion.

arithmetic problem solving questions

The PixiMaths problem solving booklets are aimed at "crossover" marks (questions that will be on both higher and foundation) so will be accessed by most students. The booklets are collated Edexcel exam questions; you may well recognise them from elsewhere. Each booklet has 70 marks worth of questions and will probably last two lessons, including time to go through answers with your students. There is one for each area of the new GCSE specification and they are designed to complement the PixiMaths year 11 SOL.

These problem solving starter packs are great to support students with problem solving skills. I've used them this year for two out of four lessons each week, then used Numeracy Ninjas as starters for the other two lessons.  When I first introduced the booklets, I encouraged my students to use scaffolds like those mentioned here , then gradually weaned them off the scaffolds. I give students some time to work independently, then time to discuss with their peers, then we go through it as a class. The levels correspond very roughly to the new GCSE grades.

Some of my favourite websites have plenty of other excellent resources to support you and your students in these assessment objectives.

@TessMaths has written some great stuff for BBC Bitesize.

There are some intersting though-provoking problems at Open Middle.

I'm sure you've seen it before, but if not, check it out now! Nrich is where it's at if your want to provide enrichment and problem solving in your lessons.

MathsBot  by @StudyMaths has everything, and if you scroll to the bottom of the homepage you'll find puzzles and problem solving too.

I may be a little biased because I love Edexcel, but these question packs are really useful.

The UKMT has a mentoring scheme that provides fantastic problem solving resources , all complete with answers.

I have only recently been shown Maths Problem Solving and it is awesome - there are links to problem solving resources for all areas of maths, as well as plenty of general problem solving too. Definitely worth exploring!
