While a Function is a predetermined formula. For example, the =SUM(A1:A4) function, this function will sum the values in the range of cells A1 through A4.
To function correctly, a function must be written in a certain way, which is called syntax. The basic syntax for a function is an equal sign (=), a function name (SUM, for example), and one or more arguments. The argument contains the information that you want to calculate. The function in the example below will add the value of the cell range A1:A4.
Functions with Multiple Arguments
Arguments must be wrapped in parentheses and can refer to specific cells and ranges of cells. Depending on the syntax required for the function, you can provide one parameter or more arguments.
Multiple arguments must be separated by a “List Separator“. For example, a SUM function with three arguments “=SUM(A1:A6,C1:C4,E1:E2)” as in the image above.
List Separator on Functions in Excel
The US-English version of Excel uses a comma (,) for the list separator by default, while other international versions may use semicolons (;).
If you try to use a “List Separator” that does not match the Region settings, you will get an error message like this:
