What is Sum in Maths?
The sum is the fundamental arithmetic operation that combines two or more quantities by adding them together to find their total. It can be used to add numbers as well as variables. Also, the sum operation is not limited to just numerical values; it can also be applied to algebraic expressions and mathematical variables.
For example, if Ram buys 20 Rs worth of bananas, 40 Rs worth of apples, and 50 Rs worth of oranges, then the total can be found by using the sum operation between 20, 40, and 50

The symbol for Sum is +. This is used when we add the numbers together. For a list of numbers in a sequence, we use the uppercase Greek letter sigma (Σ).
For example:
- 2 + 5 represents the addition of 2 and 5 which results in 7.
- a + b means the sum of two variables, a and b.
- For series with terms a1, a2, . . . ,an, their sum is represented as [Tex]\sum_{i=0}^{n} a_i[/Tex].
