    You can use =SUM(A1, B1). If you already have the above, find the name of the cell, add a comma to the end, and type in the name. An alternative to these is to type "=SUM" and then click and drag the items you would like to be included. Don't forget the closing parenthesis!

The easiest way to find the sum of a column or row of numbers is to use Excel’s AutoSum feature. Start by clicking the first empty cell below your data if summing a column, or the first empty cell next to your data if summing a row. On the Home tab, click the AutoSum button on the toolbar. This displays the SUM formula in the cell and highlights the cells to be added. Press the Enter or Return key on your keyboard to see the sum of the selected cells. You can also use the SUM function in your own formulas to add values. Let’s say you want to add the values of two cells in different columns, A2 and C5. First, click the cell where you’d like the sum to appear. Then, type an equals sign, followed by the word SUM. Immediately after, type a left parenthesis, and then the address of the first cell, A2. Next to that, type a comma, followed by the address of the other cell in your equation, C5. Type a right parenthesis immediately after that to end the formula, and then press the Enter or Return key to see the results. If you want to add more than two numbers, just type another comma after the last cell address, followed by the next cell to add. To get the sum of a range of cells, separate the cell addresses at the beginning and end of the range with a colon. You could also replace the comma with other operators, such as a forward-slash to divide, an asterisk to multiply, or a minus sign to subtract.
