Two whole numbers the result is also a whole number, but if we try subtracting two such numbers it is possible to get a number that is not in the set. The sets of numbers that are closed under multiplication are the following: A set is closed under (scalar) multiplication if you can multiply any two elements, and the result is still a number in the set. Thus, we see that for addition, subtraction as well as multiplication, the result that we get is itself a rational number.
