What does summate mean?
Summate means to add numerical amounts together and calculate their total. It is a formal verb associated especially with accounting, finance, statistics, and research, although it is used more generally wherever a precise total is required. For example, an analyst may summate sales figures before comparing them with earlier periods. The word should not be confused with “summarize”: summation is fundamentally an arithmetic process, whereas a summary expresses the principal features or conclusions of a longer subject. In ordinary conversation, speakers usually prefer “add up,” “total,” or “calculate the total.” Summate is nevertheless a useful formal term because it states the operation directly and concisely, especially when referring to the process of combining several quantities.
