# How to Check Your Math Homework Answers

## Check Your Math Answers by Using Related Statements

Solving math answers by using related statements is an easy and quick way to check your math answers.

**For Addition**

Let's say you have the addition problem *Number 1 + Number 2 = Answer*. To check the answer, you use the related subtration statement. *Number 1 + Number 2 = Answer* would become *Answer + Number 2 = Number 1*. Solve the subtraction problem and if the answer is the same on both sides, the problem is correct.

*Example:*Check

**6+5=11**.

**11-5=6**

**6=6**

**For Subtraction**To check the solution for a subtraction problem such as

*Number 1 - Number 2 = Answer*, you use the related addition statement. So,

*Number 1 - Number 2 = Answer*would become

*Answer + Number 2 = Number 1.*Solve the addition problem and if the answer is the same on both sides of the equals sign, the problem is correct.

*Example:*

Check **12-6=66+6=1212=12**

## Check Multiplication and Division Answers

**For Multiplication**

To check a multiplication problem, you use the related division statement. So, a multiplication problem such as *Number 1 x Number 2 = Answer*would become *Answer / Number 2 = Number 1*. If both numbers match, your answer is correct.

*Example:*

Check **2x3=66/3=22=2**

**For Division**You've probably guessed by now, but to double-check a division problem, you use the related multiplication statement. So,

*Number 1 / Number 2 = Answer*would become

*Answer x Number 2 = Number 1*

*.*Again, if the answers match, the answer is correct.

*Example:*Check

**8/2=4**

**4x2=8**

8=8

8=8

## Checking an Algebraic Expressions

When checking an algebraic expression, you substitute the number you found for the variable and plug it in. Don't forget about Order of Operations while checking the solution or else you may find your correct answer to be wrong. Order of Operations goes as followed, Parenthesis, Exponants, Multiplication/Division, and Addition/Subtraction.

*Example:*8t-3=7t+3 where t is supposedly 6.

8t-3=7t+3 becomes 8

**(6)**-3=7

**(6)**+3

Solve.

**48**-3=

**42**+3

**45=45**

So that means, t=6 is correct.

## Other Ways to Check Math Answers

- Check the back of your math book. Sometimes, math textbooks will include answers to certain problems.
- Use a calculator. If you are using a graphing calculator, you can usually input the whole equation instead of multiple parts if it's a complex problem.
- Use a math help site. If you Google "Check Math Answers" a lot of different sites will pop up where you can input the problem and it'll check it for you.
- Ask a parent, friend, or teacher.

## Do you LOVE or HATE math?

## What to do if the Answer is not correct.

If the answer you found is not correct do the following.

- Do
**NOT**get frustrated. - Check the problem to make sure you re-wrote it correctly.
- Go through each step of the problem and make sure you wrote down the correct answers.
- If it's still not correct, ask a friend or parent to try to solve it and see if they get a different answer.
- If you still can't figure it out, ask your teacher. They'll be glad to help you.
