Before providing the basic Excel formulas list, let’s define the key terms just to make sure we are on the same page. So, what do we call an Excel formula and Excel function?

• Formula is an expression that calculates the value of a cell.For example, `=A2+A2+A3+A4` is a formula that adds up the values in cells A2 to A4.
• Function is a predefined formula already available in Excel. Functions perform specific calculations in a particular order based on the specified values, called arguments, or parameters.

## What is a formula?

It is the simplest form, a formula is an expression made up of cell addresses and arithmetic operators. Formulas can also be made up of discrete values i.e. =6*3. Excel evaluates the formula to a value. An example of a formula looks as follows.
