Question

How to use summation notation on a calculator?

Answer 1

Hint: Here we simply have to learn how to use summation notation on a calculator.
Summation notation is nothing but a sigma notation.
The sigma notation is denoted by $${}^{\prime }{\sum }^{\prime }$$this symbol. And the sigma is nothing but the adding of the terms.
It is very easy to use summation or sigma notation on a calculator, we just have to follow some steps.

Complete step by step solution:
Given that, we have to use the summation notation on a calculator.
As the name indicates summation means sum or addition of all the terms, this is also called sigma notation, because the symbol which we use to represent the summation is $${}^{\prime }{\sum }^{\prime }$$ and this symbol is called sigma.
By using the formula of summation we can easily solve any question of addition of large numbers. But for solving it with a calculator we have to follow some steps.
So, to use the summation or. Sigma notation on a calculator we have to follow following steps as:-
Step-1:- You can see a symbol of sigma on the calculator. This can look like this. $${}^{\prime }\sum _{◻}^{◻}{◻}^{\prime }$$ click on it, you will get the all blank bores in that symbol.
Step-2:- Now, enter the value of sequence in the front bore which is just in front of the symbol. Then enter the start value at the bottom bore of the symbol and at the end enter the end value at the top bore of the symbol.
Step-3:- Now click on calculate or Answer or $${}^{\prime }{=}^{\prime }$$ sign, whatever is present in your calculator.
Step-4:- Lastly you will get the summation of the given sequence which is displayed on the screen.
So these are the steps to use the summation notation on a calculator.

Note: In this question, here asked how to use the summation notation on a calculator. Whereas the summation is nothing but the addend or summands which will result at the last in the form of sum or total.
Summation method is simple and convenient to solve and simplify the addition and it gives the exact or concise value of sum or total.
For representing the summation of the given series or sequence $${}^{\prime }{\sum }^{\prime }$$ symbols are used.
This symbol is known as sigma.
The summation can be represent in the standard form such as,
$$\sum _{x=a}^{b}x$$
Where, $$a$$and $$b$$$$=$$ limit for the given summation function.
