Addend is a mathematical term that refers to the numbers being added together in an addition problem. The word 'addend' was first used in the early 1900's and comes from the Latin word 'addendus' which means 'to be added.'. Addends are sometimes referred to as summands, and the first addend in a sequence is also called the augend. Any term can be an addend, it does not have to be a number.
