The main purpose of Excel is to perform calculations, so in this lesson we will learn the basics of performing calculations in Excel

To perform any calculation in Excel you have to write an equation, inside this equation you can use a lot of factors and functions.

Use factors

There are many factors used within the equations, the most important of which are:

How to Sum (+)

Used in combination

**For subtraction (-)**

Used in subtraction

**For Multiply (*)**

**For Divide (/)**

**For Power (^)**

**For ( & )**

Used in the integration of texts

**Priority implementation of factors**

When there is more than one operator in the equation, Excel will execute the operators according to the priority of each operator.

**Use functions**

There are a lot of functions in Excel and the function performs a particular operation and then returns the result of the execution of this operation. For example in the following figure SUM function adds all numbers in the range C1: C6 and then returns the result of the addition.

**Use factors and functions together**

You can use the factors and functions together within the equation, for example in the following figure SUM function that adds all numbers in the range C1: C6 and then returns the result of addition, then divide the result of addition by 6 using the division factor / to calculate the average of these numbers.
