Excel functions are mathematical formulas that can be used to perform calculations or other actions on data in a worksheet.
Functions can be used to perform simple tasks, such as summing a column of numbers, or more complex tasks, such as calculating a mortgage payment.
Functions can be entered into a cell directly, or they can be used in conjunction with other formulas.
