## How do you know if its a real number?

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.

## What is every real number?

The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as √2 (1.41421356…, the square root of 2, an irrational algebraic number). Included within the irrationals are the transcendental numbers, such as π (3.14159265…).

## Who invented math?

Beginning in the 6th century BC with the Pythagoreans, with Greek mathematics the Ancient Greeks began a systematic study of mathematics as a subject in its own right.
