# Sigma Notation Calculator

This sigma sum calculator computes the sum of a series over a given interval. Fill in the variables 'from', 'to', type an expression then click on the button calculate. This summation notation calculator can sum up many types of sequencies including the well known arithmetic and geometric sequencies, so it can help you to find the terms including the nth term as well as the sum of the first n terms of virtualy any series. Σ is the symbol used to denote sum. It is the uppercase Greek letter sigma.
