What is the Sigma (Σ) Notation Calculator?

The Sigma (Σ) Notation Calculator is a tool that calculates the total sum of a mathematical expression over a specific range by using the sigma notation method, where you enter a formula with the variable x and choose starting and ending values so the calculator evaluates the expression at each step and adds all the results together, helping students easily solve sequences, series, and summation problems without manual calculation.
