What is a "double fact"?
For that matter, what is a "single fact"? On the Fifth grader show yesterday, there was a question about a "double fact".
I was a math major (more than 5 years ago!), but I have never heard of a "fact". I couldn't find a definition of "fact" anywhere on-line.
Can somebody give me a reasonably good definition? Thanks.
The question was, "What number needs to be added to 3 to give a double fact?" Or something like that.

Without more context, it's hard to give an accurate guess, but it might be talking about "doubles" as in 7 + 7 = 14 and 12 + 12 = 24.
Also, items such as "1 + 5 = 6" and "5 + 7 = 12" are called "math facts."
EDIT: well, then the answer would be 3 to make it a double.

Math Doubles Facts 1+1=2, 2+2=4 , 4+4=8
Doubles and near doubles: If you have two groups of 8 objects, you have double 8, or 16, objects. Doubles facts are usually easy to remember , and can be used to learn other facts. Since 8+8=16, and 9 is one more than 8, 8+9 will be one more than 16, or 17.
