In mathematics, a fact family consists of three numbers that are related through addition and subtraction. For the numbers 7, 9, and 63, the fact family would be: 7 + 9 = 16, 9 + 7 = 16, 16 - 7 = 9, and 16 - 9 = 7. These equations demonstrate the relationships between the three numbers in the fact family, showing how they can be combined and separated using addition and subtraction.
A fact family is when the same 3 numbers are used in addition and subtraction sentences. An example would be 3+4=7, 4+3=7, 7-4=3 and 7-3=4
7+5=12 5+7=12 12-5=7 12-7=5
It could be that 7*6 = 42 and that 42/7 = 6
7 14 21 28 35 42
6 * 7 = 42 7 * 6 = 42 42 / 6 = 7 42 / 7 = 6
This is the identity property of addition.
