Base (numbers)

Base (numbers)
Definition 1: The number that gets multiplied when using an exponent.

Examples:
• in 82, 8 is the base, and the result is 8 × 8 = 64
• in 53, 5 is the base, and the result is 5 × 5 × 5 = 125



Definition 2: How many numbers in a number system.

The decimal number system that we use every day has 10 digits {0,1,2,3,4,5,6,7,8,9} and so it is Base-10.
Binary digits can only be 0 or 1, so they are Base-2.
