What does classify the real number mean?

The classifications of numbers are: real number, imaginary numbers, irrational number, integers, whole numbers, and natural numbers. Real numbers are numbers that land somewhere on a number line. Imaginary numbers are numbers that involve the number i, which represents √−1.

How did you classify the number as real or not real?

Irrational numbers and rational numbers are two distinct classifications — a rational number (and integers, whole numbers, or natural numbers) can’t be irrational. Rational numbers and irrational numbers together make up the real numbers.

What does not classify as a real number?
