Formulas and Functions

Formulas were created and used to make math more easier. There are many different formulas for many different situations that you can think of. But finding which formula to use and actually solving the problem takes time, but you can use Excel and it will help make your life more easier. Formulas are used for calculating numbers, both big and small. Excel already has built in formulas in the program, all you have to do is plug in the numbers and everything is taken care of. If formulas were not created, finding out the square root of a number that is not perfect will take a lot of time and patience.
