sum

In mathematics, a sum is the result of adding numbers together. For example, the sum of 5 and 7 is 12. This operation is a fundamental part of arithmetic, which is the branch of mathematics dealing with numbers and their operations. The process of addition follows certain laws, such as the commutative law, where the order of numbers does not change the sum (a + b = b + a), and the associative law, where the grouping of numbers does not affect the sum (a + b) + c = a + (b + c). The term "sum" can also refer to the aggregate of numbers or quantities considering their signs, known as an algebraic sum.12345
