The word "summation" originates from the Latin term "summatio", which is derived from the verb "summare", meaning "to sum up" or "to total". "Summare" is a combination of the prefix "sub-" (meaning "up to" or "under") and the verb "movere" (meaning "to move"). Hence, "summation" came to represent the action of adding things together or bringing them to a final total.
