Introduction to Functions
4
What are functions? A function is a shortcut to the most common mathematical calculation which also begins with an equals sign (=). Examples: =SUM(B2:B5) =AVERAGE(B2:B5) =MIN(B2:B5) =MAX(B2:B5)
5
3 Parts of a Spreadsheet Function Start with Equals Function Name Range of Cells
6
Identifying Parts of a Spreadsheet Function =SUM(B2:B6) Equal sign Function Name Range 1 st Cell Last Cell
7
Function NameDescription AVERAGEAverage or mean of the range of cells. MAXMaximum value of the range of cells. MINMinimum value of the range of cells. SUMTotals a range of cells. Spreadsheet Functions
8
Identifying Functions Function The result of the function Look in the data entry bar to determine if the number is a value or function.
