5. Function oFunctions are something the user tells the spreadsheet to do to the data. SUM adds selected data. MIN finds the smallest in all the data. MAX finds the largest in all the data. AVERAGE finds a mean average of all the data. IF you set a condition, and two responses, as to whether the data in the condition was correct or not.
