Worksheet Overview

From any addition fact such as

35 + 23 = 58

we can work out two subtraction facts.

Here we get

58 - 35 = 23

and

58 - 23 = 35

This is handy because we can use additions to check subtractions.

Example 1

Anna says that

33 - 15 = 18

Use addition to check if she is right or wrong.

18 + 15 = 33

So Anna is right.

Example 2

Ben says that

54 - 15 = 31

Use addition to check if he is right or wrong.

31 + 15 = 46 not 54

So Ben is wrong.
