## SUM Function

Excel sum functions are some of the most commonly used functions in the program. They allow users to quickly and easily add up a range of cells or a set of numbers. In this article, we will go over how to use the sum function in Excel, as well as some tips and tricks for getting the most out of it.

To use the sum function in Excel, first select the cells that you want to add up. You can do this by clicking and dragging your mouse over the cells, or by holding down the shift key and using the arrow keys to select the cells. Once you have your cells selected, you can use one of the following methods to sum them up:

1. Type “=SUM(” into the formula bar at the top of the spreadsheet and then select the cells that you want to add up. Excel will automatically add a closing parenthesis at the end of your formula. Press enter to see the result.
2. Use the AutoSum button on the Home tab of the ribbon. This button looks like a Greek sigma symbol (∑) and is located in the Editing group. When you click the button, Excel will automatically select a range of cells that it thinks you want to sum up, and will insert a sum formula into the cell to the right of the selected cells. You can then press enter to see the result.
3. Use the keyboard shortcut Ctrl + Shift + =. This shortcut will automatically insert a sum formula into the cell to the right of the selected cells, just like the AutoSum button.

Once you have your sum formula in place, you can edit it if needed by clicking on the formula in the formula bar and making any changes. For example, you might want to add a range of cells that is not adjacent to the ones you originally selected. To do this, you can simply type the cell range into the formula, using a colon to separate the first and last cells in the range. For example, to add the values in cells A1, A2, and A3, you would type “=SUM(A1:A3)” into the formula bar.

There are also a few tips and tricks that can help you get the most out of the sum function in Excel. These include:

1. Use the AutoSum button or keyboard shortcut to quickly add up a range of cells. This can save you a lot of time, especially if you have a large spreadsheet with many cells to add up.
2. Use absolute cell references when you want to add up a specific range of cells no matter where the formula is copied. To do this, put a dollar sign (\$) in front of the row or column reference in the cell range. For example, to add up the values in cells A1, A2, and A3 no matter where the formula is copied, you would use the formula “=SUM(\$A\$1:\$A\$3)”.
3. Use the SUMIF function to add up cells that meet certain criteria. For example, you might want to add up all the values in a column that are greater than a certain number. To do this, you would use the formula “=SUMIF(range, criteria, sum_range)”. The “range” is the column of cells that you want to check, the “criteria” is the condition that must be met (e.g. “>10”), and the “sum_range” is the column of cells that you want to add up.
4. Use the SUMIFS function to add up cells that meet multiple criteria. This function works just like the SUMIF function, but allows you to specify multiple criteria.
