what are function in Excel
Answers
Answer:
Microsoft Excel's table structure is a great way to keep organized. But the program is much more than just a series of rows and columns into which you can enter data.
Excel really becomes powerful once you start using functions, which are mathematical formulas that help you quickly and easily make calculations that would be difficult to do by hand.
Functions can do many things to speed up your calculations. For example, you could use functions to take the sum of a row or column of data; find the average of a series of numbers; output the current date; find the number of orders placed by a particular customer within a given period of time; look up the e-mail address of a customer based on his or her name; and much more. It's all automatic — no manual entry required.
