Just **select an empty cell directly below a column of data.** **Then on the Formula tab, click AutoSum > Sum**. Excel will automatically sense the range to be summed. (AutoSum can also work horizontally if you select an empty cell to the right of the cells to be summed.)

The SUM function adds values. You can add individual values, cell references or ranges or a mix of all three. For example: =SUM(A2:A10) Adds the values in cells A2:10.

If you need to sum a column or row of numbers, let Excel do the math for you. Select a cell next to the numbers you want to sum, click AutoSum on the Home tab, press Enter, and you're done. When you click AutoSum, Excel automatically enters a formula (that uses the SUM function) to sum the numbers.

Click the table cell where you want your result to appear. On the Layout tab (under Table Tools), click Formula. In the Formula box, check the text between the parentheses to make sure Word includes the cells you want to sum, and click OK. =SUM(ABOVE) adds the numbers in the column above the cell you're in.

How to Use the Sum Function in Microsoft Excel

- Writing a Sum Formula.
- Using AutoSum.
- Copying the Sum Function to Other Columns.

Sum a column or row of numbers in a table

- =SUM(ABOVE) adds the numbers in the column above the cell you're in.
- =SUM(LEFT) adds the numbers in the row to the left of the cell you're in.
- =SUM(BELOW) adds the numbers in the column below the cell you're in.

How to Apply Formula to Entire Column in Excel (5 Easy Ways)

- By Double-Clicking on the AutoFill Handle.
- By Dragging the AutoFill Handle.
- Using the Fill Down Option (it's in the ribbon) Adding the Fill Down in the Quick Access Toolbar.
- Using Keyboard Shortcut.
- Using Array Formula.
- By Copy-Pasting the Cell.

For example, to sum one column of cells, you may use "=SUM(A2:A32)" or to sum two columns you may use "=SUM(A2:A32,B2:B32)." Press "Enter" to display your results in the selected cell. If you added two columns with the range argument, the formula displays the results of both ranges added together.

Unlike other Microsoft 365 programs, Excel does not provide a button to number data automatically. But, you can easily add sequential numbers to rows of data by dragging the fill handle to fill a column with a series of numbers or by using the ROW function.

Auto-fill is a feature that lets you create a series of numbers, dates, or other data automatically. To use it, simply select the cells you want to fill and enter the first value. Then, drag the fill handle (the small square in the bottom-right corner of the cell) down or across to the cells you want to fill.

The pattern used to do addition is the same no matter how many digits are in the numbers or how many numbers you are adding together. Stack the numbers according to place value. Add the numbers in the columns starting with the column on the right. Carry numbers into the next place value to the left as needed.

Auto number a column by AutoFill function

Type 1 into a cell that you want to start the numbering, then drag the autofill handle at the right-down corner of the cell to the cells you want to number, and click the fill options to expand the option, and check Fill Series, then the cells are numbered. See screenshot.

Quickly Fill Numbers in Cells without Dragging

- Enter 1 in cell A1.
- Go to Home –> Editing –> Fill –> Series.
- In the Series dialogue box, make the following selections: Series in: Columns. Type: Linear. Step Value: 1. Stop Value: 1000.
- Click OK.

The most common reason for AutoSum not working in Excel is numbers formatted as text. At first sight, those values may look like normal numbers, but Excel regards them as text strings and does not include in calculations.

To sum multiple columns or rows of data, select the cells you want to sum, then click the AutoSum button. The sum function will be inserted into the cell. You can then enter the cells you want to sum. To sum multiple columns or rows of data, select the cells you want to sum, then click the AutoSum button.
