# Excel Functions

In our website, we do not refer to Excel worksheet functions as functions. They are called Excel Formulas. This is because Excel worksheet functions are used within a cell together with the basic mathematical operations such as addition, subtraction, multiplication and division.

In our website, functions refers to another group of tools that is very powerful in managing data in worksheets. They include pivot table, Scenario Analysis, Solver, Subtotal, etc.
