# Summation Notation

Summation notation, also known as sigma notation, is a concise mathematical representation used to express the summation of a series of terms. It provides a succinct way to denote the addition of multiple terms without explicitly listing each one. Commonly encountered in various branches of mathematics, particularly in calculus, statistics, and discrete mathematics, summation notation facilitates the compact representation of repetitive operations. By utilizing symbols such as the Greek letter sigma (Σ), it streamlines the communication of complex mathematical concepts, making it an invaluable tool for expressing sums efficiently and precisely.

Questions

- Summation of series(method of differences),When we use #∑f(r)-f(r+1#),how can we know it is #f(1)-f(n+1)#, but not #f(n)-f(1+1)#? Also, how can we know it is #f(n+1)-f(1)# but not #f(1+1)-f(n)# when we use #∑f(r+1)-f(r)#?
