# Sigma Notation

Sigma notation, often denoted by the symbol Σ, is a concise mathematical representation used to express the sum of a sequence of terms. Widely employed in various branches of mathematics, this notation provides a convenient way to articulate repetitive additions. It succinctly captures the essence of summation, allowing mathematicians to express complex series with clarity and brevity. By encapsulating the cumulative nature of mathematical operations, sigma notation enhances the efficiency of conveying mathematical concepts and facilitates concise communication in the realm of equations and series.
