summed

Summed is the past tense and past participle of sum. In mathematics and common usage, it means to add together two or more numbers, quantities, or values to obtain a total. When items are summed, the result is called the sum.

In formal contexts, summing is the operation of adding the terms of a finite or infinite sequence. For finite sequences, the result is a finite sum; for infinite sequences, the sum is defined only when the series converges. Summation is often denoted with sigma notation, and partial sums are used to study convergence.

In computing and data analysis, "summed" describes data that have been aggregated by addition. Examples include summing rows to produce a column total or computing a summed score in questionnaires, where item responses are added to yield an overall score. The term is closely related to related concepts such as sum, summation, and cumulative sum.

In everyday language, the phrase "the totals were summed" or "the costs were summed" conveys combining values to reach a final total. The word "sum" is the noun form; "summation" is the process or the act, while "summed" is the verb form used to describe completed addition.
