ABSTRACT

Numeric data are bit collections which people view as representing numbers of some kind. Often the computer is working with memory addresses, which are always non-negative. For this use, unsigned integers, which use all bit configurations to represent non-negative integers, allow for the representation of a larger range of addresses. Although computers, obviously, do perform subtraction, this statement is meant to indicate that processors contain very little circuitry dedicated to subtraction, but rather use the same circuitry they use for addition. In decimal, long division involves subtracting multiples of the divisors from the dividend. The multiplied divisor is shifted towards the right, as the remaining dividend becomes smaller and smaller. Each multiplier, used to multiply the divisor, is recorded at the top, and becomes one of the digits of the quotient. As with multiplication a person makes a modification with the shifting direction.
