Basic Math functions: Allows you to use the basic math symbols to perform mathematical functions. You can use the following keys: $($plus sign to add$),-($minus sign to subtract$),*($asterisk sign to multiply$),$ and $/($forward slash to divide$).$ From the Excel Simulation below, a blank cell $"=B9+B10"$ was entered, the formula would add the values from those cells and output the result, or $17,250$ in this example. using the other math symbols the result would output an appropriate answer for its function.

SUM function: Allows you to refer to multiple cells and adds all the values. You can add individual cell references or ranges to utilize th function. From the Excel Simulation below, if in a blank cell $"=$SUM$($B$13,$B$14)"$ was entered, the formula would output the result of adding those two separate cells, or $737,320$ in this example. Similarly, if in a blank cell $"=$SUM$($B$13$:B$14)"$ was entered, the formula would output
