subtraction
Quick Summary
Subtraction is a fundamental arithmetic operation where one number, the subtrahend, is taken away from another number, the minuend. The result of this operation is called the difference. The symbol used to denote subtraction is a hyphen or minus sign (–). For example, if you subtract 10 from 23, the result is 13. Subtraction is the inverse of addition, meaning that if you add the subtrahend back to the difference, you will get the original minuend. Another related concept is the additive inverse, which is a number that, when added to a given number, results in zero.1234

…vectors can be added or subtracted. For example, to add or subtract vectors v and w graphically (see the diagram), move each to the origin and complete the parallelogram formed by the two vectors; v + w is then one diagonal vector of the parallelogram, and v − w
