Number Bases. Numbers are the foundation of all mathematics, but did you know that the way we represent them depends on the base we use? The base of a number system tells us how many digits are used before the digits start repeating in patterns. The most common base we use in everyday life is Base 10 , also called the Decimal System . However, there are many other bases such as Binary (Base 2) , Octal (Base 8) , and Hexadecimal (Base 16) — all widely used in computing and digital systems. What Is a Number Base? A number base (or radix ) is the number of unique digits used to represent numbers in a positional number system. For example: In Base 10 , we use digits 0 to 9. In Base 2 , we use digits 0 and 1 only. In Base 8 , we use digits 0 to 7. In Base 16 , we use digits 0 to 9 and letters A to F (representing values 10 to 15). So, the value of ea...
