The first step is to enter a capital sigma and then assign values to it.
Adding numbers does not seem like a difficult task, does it? However, There might be some problems that are not easy to solve. For example, a teacher might ask you to calculate, say, the sequence of square numbers. Of course, you can enter the numbers one by one and get the sum in the end. But it will take you a lot less time to use the summation calculator and the symbol of E. It is a Greek letter, Sigma, and represents a sum of numbers. Here's an example:
As you might have noticed, there are upper and lower limits. This is a way of showing the part of the sequence you need to calculate. Once you get your head around the way this formula works, it will be easy to solve any problem on this topic. Here's one more example:
