Functions are formulas that Excel has predefined. These functions are designed to quickly perform calculations with a minimum of effort on the part of the user. Excel has already determined the necessary mathematical steps required and only needs to be given the arguments in order to complete the calculation—that is, the cell addresses or ranges where pertinent information is stored. There are over 200 built-in functions in Excel 2007 and over 300 in Excel 2010. While a few commonly used functions were covered in Excel I, II, and III, this course covers a broader spectrum and introduces the student to a wide range of useful and versatile functions that most users haven’t discovered yet. Prerequisite: Excel I and II or equivalent knowledge
