#### Sigma notation is a method used to write out a long mathematical expression or sequence in a concise way. There are situations where students are required to add an infinite quantity, and as you know, it is impossible to add a quantity infinite times, not something humanly possible. But, math always comes to rescue; even, in this case, there is an easy way to do that. This is when we can bring the concept of 'series' in the light. It is a major part of calculus and something that we can help us in our day-to-day activities. Series is the process or operation of adding infinitely many quantities to a given first quantity. While we discuss series, there is one important concept that you need to be well-aware of, and that is the sigma notation of series. So, what is the sigma notation of a series? Sigma is a Greek letter, denoted by Σ { , } which is used to represent a 'sum.'

In these worksheets, your students will learn to use sigma notation to express the value of sequences. They will simplify expressions using sigma notation.
