In mathematics, a sum is the result of adding two or more numbers or quantities together. It represents the total amount obtained after combining all addends in an addition operation. The term is used in basic arithmetic, algebra, and higher-level mathematics to describe the outcome of a series of additions, whether they involve simple integers, fractions, variables, or more complex expressions. In everyday language, "sum" can also refer to a specific amount of money or a quantity in general, but its core meaning remains tied to the idea of totalizing or aggregating multiple parts into one overall result.
