Unite two quantities to form a sum. Apply positive and negative signs based on a topic's relative qualities.
Addition
Addition is the process of uniting two or more quantities into one equivalent expression, called their sum.
Since, in algebra, the quantities to be added may be either positive or negative, it is necessary to consider here more fully the nature of the signs + and -. Thus far they have been employed to indicate simply the opposite processes of addition and subtraction. They have, however, a wider significance, and indicate not only operations to be performed, but the quality or relative character of the quantities to which they are applied. They may denote opposite directions in space, opposite effects in nature, or opposite results in business. Thus, if plus indicates north, minus will indicate south; if plus indicates heat, minus will indicate cold; and if plus indicates gain, minus will indicate loss.
