The term 'total amount' can be described in several ways. The three letter solution, ALL, means the entire amount or the whole SUM. The five letter solution, GROSS, refers to the total before any deductions are made. The nine letter solution, AGGREGATE, is the combination of several amounts or elements into one SUM. Finally, the three letter solution, SUM, is the result of adding two or more numbers together. All of these terms refer to the same concept, the total amount.
