What is Summation?
Summation is the addition of a sequence of any kind of numbers, called addends or summands; the result is their sum or total. The uppercase Greek letter Sigma (Ī£) is used as a symbolic shorthand for the sum of many terms.

Pro Tips
The start index must be less than or equal to the end index.
Polynomial summation can also be solved using closed-form identities for i, iĀ², and iĀ³.
Sigma notation is widely used in physics, statistics, and computer science algorithms.

Fun Facts
"The symbol Ī£ was introduced by Leonhard Euler in 1755."
"The sum of the first 100 integers is 5,050 (famously calculated by a young Gauss)."
"Infinite summations are called 'series' and can converge to a finite value."
