Microsoft Excel lets you use formulas and functions to perform basic and advanced numerical calculations. You can do addition, subtraction, multiplication, division, mean, worke with strings, and many others.
In Excel, the difference between a formula and a function is that a function is a predefined calculation while a formula is a user-defined calculation.
For example, SUM is a function while =SUM(E1:E9) is a formula using the SUM function.
In this article, I will show you Excel formulas and functions that will make life easier for you any time you’re working with Excel. You will also learn how to use each of the formulae.
