A number base is the number of unique digits, including zero, used to represent numbers in a numeral system. Commonly used bases include decimal (base-10), binary (base-2), and hexadecimal (base-16).
More Information
The most commonly used base is decimal, or base-10, because it uses digits 0-9. Binary, base-2, uses only digits 0 and 1, which is key to computer programming.
Tips
When working with number bases, it is important to remember the highest digit possible is always one less than the base. For example, in base-8, digits go from 0 to 7.
