What is a set of numbers?

What are common number sets? In mathematics, there are multiple sets: the natural numbers N (or ℕ), the set of integers Z (or ℤ), all decimal numbers D or D , the set of rational numbers Q (or ℚ), the set of real numbers R (or ℝ) and the set of complex numbers C (or ℂ).

How do number sets work?

In a finite number of elements in a set, the order is equal to the number of elements in the set. For instance, the set {2, 4, 6, 8} has order 4, because it has four numbers in it. When there are an infinite number of elements in a set, the order of the set is infinite.
