In mathematics, the real numbers may be described informally as numbers that can be given by an infinite decimal representation, such as 2.4871773339…. The real numbers include both rational numbers, such as 42 and â23/129, and irrational numbers, such as Ï and the square root of 2, and can be represented as points along an infinitely long number line.

Real numbers are real when a number started on 1 – 9 only.

There should only be one non-zero number.
