In this worksheet, students must find the missing number in a sum by using addition and subtraction. Key stage:  KS 2

Curriculum topic:   Number: Addition and Subtraction

Difficulty level:   #### Worksheet Overview

In this worksheet you must find the missing number in a sum.

Example

Find the number that makes the sum correct.

4740 + __ = 6000

The opposite (inverse) of adding is subtracting.

So we work out 6000 - 4740 = 1260

Here is another example

2365 + ___ = 4000

Use the inverse operation to solve.

4000 - 2365 = 1635
