In mathematics, the term “sum” refers to the result obtained by adding together two or more numbers or quantities

In mathematics, the term “sum” refers to the result obtained by adding together two or more numbers or quantities. It is essentially the total or the aggregate of the individual values or terms being added.

For example, if we have the numbers 3, 4, and 7, then their sum would be 3 + 4 + 7 = 14. In this case, 14 is the sum of the three numbers.

The sum is a fundamental operation in arithmetic and is represented by the symbol “+”. It is an associative operation, which means that the grouping of terms being added does not affect the result. In other words, (a + b) + c = a + (b + c).

The concept of sum is not limited to just numbers. It can also be used in various other mathematical contexts, such as adding together vectors, matrices, or even infinite series. In calculus, the sum of infinitely many terms is known as a series, and the concept of convergence is used to determine whether the sum exists and what its value may be.

It is important to note that the sum is a commutative operation, meaning that the order of the terms being added does not affect the result. Therefore, a + b = b + a.
