In daily work and study, SUM is an extremely widely used function and can be learned as an entry-level function. Therefore, overall, the SUM function is not difficult but has a wide range of applications. But don’t underestimate SUM just because it is simple. It also has some little-known tricks! 1. Cumulative summation is as shown below. It is the sales performance of a certain company every day, and it is required to calculate the daily cumulative amount.
For example, enter the formula in cell D2: =SUM(C$2:C2), press the Enter key to complete and fill downwards.
Note: At this time, C$2 must lock the row mark, so that a reference area from the second row to the downward row will be generated during the pull-down process.
2:Sum with qualified cells
The sum of merged cells has always been a troublesome problem for novices.
Select the cell range D2:D13, then enter the formula in the formula editing bar: =SUM(C2:C13)-SUM(D3:D14), and then press Finish. Note: Be sure to pay attention to the range of the second SUM function. Misplaced, otherwise an error will be reported.
3: Sum of cells with subtotals
How to sum cells with subtotals? In cell C9, enter the formula: =SUM(C2:C8)/2 and press Enter to complete.
The process of subtotaling and summing are used here to repeatedly calculate the above data, so dividing by 2 can get a non-repeating result, which is exactly the desired result.Recommended by the editor of Huajun Software Park
