Introduction

This article will be an introduction to number systems. Here we see the different types of number systems represented in mathematics.

A number system is a writing system where digits and symbols are used consistently to represent values.

The exact sequence of symbols may represent different numbers in different number systems.

Mathematics has various types of number systems, like binary, decimal, octal, and hexadecimal.

Number system

Number System Base Used Digits
Binary 2 0, 1
Octal 8 0, 1, 2, 3, 4, 5, 6, 7
Decimal 10 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal 16 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

Of all these number systems, decimal and binary are the most important for bit manipulation.

In the next lesson, we will discuss these two number systems in detail.
