spreadshet formula to add totals​

In a spreadsheet, to add totals of a set of numbers, you can use the SUM function. The SUM function adds up all the numbers you specify as arguments. Each argument can be a range, a cell reference, or a fixed number.

Here's a step-by-step guide on how you can use the SUM function:

1. Click on the cell where you want the total to appear.

2. Type in `=SUM(` to start the formula.

3. Highlight the cells you want to add together with your mouse, or type in the range of cells.

For example, if you want to sum numbers in cells A1 to A5, you would enter `A1:A5` within the parentheses.

4. Close the parentheses after you've entered all the cell references or ranges. 5. Press Enter, and the spreadsheet will calculate the total of the cells you specified.

For example, the full formula looks like this: `=SUM(A1:A5)`

In this case, if A1 through A5 have the values 2, 3, 4, 5, and 6, respectively, the formula `=SUM(A1:A5)` would return the total, which is 20.
