All numbers - integers as well as non-integers - are combined using different mathematical operations. Some operators are binary: that is, they combine two numbers to produce a third; some are ternary (combine 3 to produce a fourth) and so on.
The set of integers is closed under some operations: common examples are addition, subtraction, multiplication, exponentiation. But not all operators are: division, for example.

How do you do multiplication problems with decimal points?
You multiply the numbers like you multiply integers. Count how many numbers are after the decimal points in both numbers combined and move the decimal point in front of the answer.
9 squared belongs to what family of real numbers?
At least the following families: all integers; all positive integers; all odd integers; and all "square integers", that is, integers that are squares of other integers.
