what is sum in maths

In mathematics, the term "sum" refers to the result obtained when we add two or more numbers or terms. The numbers being added are called addends or summands. The sum is a way of putting things together, and it is the process of bringing two or more numbers together to produce a new result or total. The sum can be represented by the symbol "+" or the symbol ∑ (sigma) . The sum of a sequence of numbers is denoted as a succession of additions, and the order of the summands does not affect the result due to the associative and commutative properties of addition. The summation symbol is used to compactly represent the summation of many similar terms. The sum can be used to find the total number of objects or things, and it is an important concept in mathematics.
