What is Numbers?

“Numbers” stands for mathematical entities that are used for counting, measurement, and all calculation processes.

To a large extent, they are essential elements of mathematics because they serve as a base for almost all concepts and operations in mathematics. What’s more, numbers are classified according to the different types they belong to: the natural numbers (1, 2, 3…), integers (… -3, -2, -1, 0, 1, 2, 3…), rational numbers (fractions), and real numbers (both rational and irrational numbers). Furthermore, there are complex numbers, which are the numbers that we can write in a + bi form where the imaginary unit “i” is √(-1). Numbers are in constant use for a lot of fields that can be classified into science, engineering, finance, and one’s ordinary life as well. In this sphere, they are used to quantify, analyze, and solve problems.
