Considerations when using the SUM function
The SUM function uses the following arguments:
- Number1 (required argument) – This is the first item that we wish to sum.
- Number2 (required argument) – The second item that we wish to sum.
- Number3 (optional argument) – This is the third item that we wish to sum.
The function sums values supplied as arguments (up to 255 arguments). Arguments can be supplied as numbers, cell references, ranges, arrays, constants, and the results of other formulas or functions.
If you want to filter the values that you are summing, you can use the SUMX function and specify an expression to sum over.
