Many concepts and facts are related. These relations constitute fact families. In fact families, when you add two numbers, you get the same result irrespective of which order the numbers are in. Similarly, when you subtract any one of the two numbers from the result, you get the other number. For example:
2 + 3 = 5
3 + 2 = 5
5 – 3 = 2
5 – 2 = 3
