Why does the Fact family for 81 and nine have only two number sentences
because you need 3 different numbers for 4 sentences
If a fact family has only 2 multiplication nd division sentences, what do you know about the product and divident?
There are only two numbers in that case. For example 5 x 5 = 25 and 25/5 = 5. The fact family has only two sentences. Now from the equation it indicates that the product of the same numbers gives the dividend or dividend divided by divisor is the same number as the divisor since there are only two numbers in the fact family.
this is when there are the same digit numbers in the sentence
It has only 2 numbers: 9 and 81. Since 9 squared (9^2, 9*9). So all there is is:9 × 9 = 8181 = 9 × 9
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!
The fact family for 81 has more than 2 factors: 1, 3, 9 are factors: and that is more than two!
