Question 399234: to which subsets of the real numbers does the number 22 belong ?
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! It can apply to lots of different subsets, including but not limited to, rational numbers, integers, whole numbers, natural numbers. However the definition of "subset" in this problem is ill-defined, we can define a subset of the real numbers as all multiples of 2, or all numbers that are six less than a perfect number, and 22 appears in both of these.
