What is a Number?

A number is a mathematical object used to count, label, and measure. In mathematics, the definition of number has been extended over the years to include such numbers as 0, negative numbers, rational numbers, irrational numbers, real numbers, and complex numbers.

For this, the natural numbers were a good start. The work of mathematicians led us to discover other types of numbers. Whole numbers are an extension of natural numbers that include negative integers. Rational numbers, in turn, include fractions of integers. Real numbers are all rational numbers plus irrational numbers. (wikipedia)
