Describe real numbers, Mathematics

Q. Describe Real numbers?

Ans.

There are a few different ways to describe real numbers. Without going into any of the very technical definitions used by mathematicians, I'll just say that a real number is ...

  • Any rational or irrational number;
  • Any number which can be written as a decimal.

 

The set of real numbers includes everything I've mentioned so far, including rational numbers, integers, and whole numbers. Here are some examples of real numbers:

The set of real numbers is closed under addition, subtraction, multiplication, and division.

By the way, there is sometimes more than one way to write a decimal number. For example, 1.0 and 0.99999... are the same number.
