## subtractionThe binary operation of finding the difference between two quantities or numbers; the inverse of addition. The difference of two numbers, a - b, is the number that
has to be added to b to give a. a is called the
minuend and b the subtrahend.
Subtraction can also be seen as the solution of an equation since the difference
(a - b) may be expressed as b + x = a.
The subtraction of negative numbers
is equivalent to addition, since a - (-b) = a
+ b. ## Related category• ARITHMETIC | |||||
