What is sum meaning?

Sum refers to the result obtained when two or more numbers are added together. It is one of the basic mathematical operations and is often represented by the symbol '+'. The sum of any two or more numbers can be found by adding them together. For example, the sum of 2 and 3 is 5, which is obtained by adding these two numbers: 2 + 3 = 5.

In addition to arithmetic, sum can also refer to the total amount of money, goods or any other value that is accumulated or added up over time. For instance, the sum of all the expenses incurred in a project, the sum of money spent on a particular investment, or the sum of all the scores in a game or competition.

In mathematical contexts, the term 'sum' may also refer to a series of numbers that are added together, and the result is called the sum of the series. Such series can be finite or infinite, and they play an essential role in many areas of mathematics, including calculus, number theory, and probability theory.
