fact family are related facts Number family are related numbers

A "fact family" is when the same 3 numbers are used in 4 different equations of addition and subtraction (2 of each) or multiplication and division (once again, 2 of each). For example: 6-4=2, 6-2=4, 4+2=6, 2+4=6. Another example would be: 3x4=12, 4x3=12, 12/4=3, 12/3=4.

There cannot be such a family because of self-reference. It is similar to the Russell paradox (named after Bertrand Russell). As soon as you have a fact family with only two facts, you have added a third fact. The third fact is that is that the fact family had only two facts. That then makes it a family with three facts. Which means it is no longer a fact family with only two facts. So the third fact is no longer correct. And so it does not have three facts. Which means it has only two facts and you will keep looping round and round forever!
