subtraction
subtraction, fundamental operation of arithmetic; the inverse of addition. If a and b are real numbers (see number), then the number ab is that number (called the difference) which when added to b (the subtractor) equals a (the subtrahend). In terms of addition the symbol b is called the additive inverse of b with the property that the sum of a number and its inverse equals 0, or b+(b)=0. It follows that (b)=b. The subtraction of b from a is the same as the addition of a and the inverse of b, or ab=a+(b); e.g., when a=10 and b=5, then 105=10+(5).
