What is real line

Dear Student,
Numbers are the basic foundation of mathematics. We learn about different types of numbers in math. Basically, the numbers are divided into two classes- real and imaginary. The real numbers further include rational numbers and irrational numbers. Rational numbers consist of natural numbers, whole numbers, and integers.
As the name suggests, the real line is a line that denotes real numbers on it. The points on this line represent real numbers. We can denote the number line by R or R1( symbolize one-dimensional real line)

Regards!
