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
2x7=14, 7x2=14, 14/2=7, & 14/7=2
7+5=12 5+7=12 12-5=7 12-7=5
7 14 21 28 35 42
It could be that 7*6 = 42 and that 42/7 = 6
This is the identity property of addition.
