Unsigned Binary Arithmetic

Unsigned binary numbers are, by definition, positive numbers and thus do not require an arithmetic sign. An m-bit unsigned number represents all numbers in the range 0 to 2m − 1.

For example, the range of 8-bit unsigned binary numbers is from 0 to 25510 in decimal and from 00 to FF16 in hexadecimal.
