What are the 4 types of real numbers?
A. There are 5 classifications of real numbers: rational, irrational, integer, whole, and natural/counting.
How do you identify real numbers?
One identifying characteristic of real numbers is that they can be represented over a number line. Think of a horizontal line. The center point, or the origin, is zero. To the right are all positive numbers, and to the left are the negative points.
Is zero a real number?
The number 0 may or may not be considered a natural number, but it is an integer, and hence a rational number and a real number (as well as an algebraic number and a complex number). The number 0 is neither positive nor negative, and is usually displayed as the central number in a number line.
