Subtraction: Use number sentence to write new number sentences

In this worksheet, we will learn about three more facts that you can get from just one subtraction fact.

For Example:

If we know that 7049 - 2143 = 4906

Then we can also write three more facts about these numbers.

7049 - 4906 = 2143
4906 + 2143 = 7049
2143 + 4906 = 7049

Here is an easier example:

If we know that 100 - 30 = 70

Then we can also work out the following:

100 - 70 = 30

70 + 30 = 100

30 + 70 = 100
