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
