Click the cell in which you want to create a formula. You can add, subtract, divide, and multiply cell values with the following formulas:   Add — Type =SUM(cell+cell) (e.g., =SUM(A3+B3)) to add two cells' values together, or type {{kbd|=SUM(cell,cell,cell) (e.g., =SUM(A2,B2,C2)) to add a series of cell values together.  Subtract — Type =SUM(cell-cell) (e.g., =SUM(A3-B3)) to subtract one cell value from another cell's value.  Divide — Type =SUM(cell/cell) (e.g., =SUM(A6/C5)) to divide one cell's value by another cell's value.  Multiply — Type =SUM(cell*cell) (e.g., =SUM(A2*A7)) to multiply two cell values together. If you want to add all of the numbers in a whole column (or in a section of a column), type =SUM(cell:cell) (e.g., =SUM(A1:A12)) into the cell you want to use to display the result. To use a more advanced formula, you'll use the Insert Function tool. Start by clicking the cell in which you want to display your formula. It's a tab at the top of the Excel window. This option is in the far-left side of the Formulas toolbar. Doing so opens a window. Click in the window the function you want to use, then click OK. For example, to select the formula for finding the tangent of an angle, you would scroll down and click the TAN option. When prompted, type in the number (or select a cell) for which you want to use the formula.  For example, if you select the TAN function, you'll type in the number for which you want to find the tangent. Depending on your selected function, you may need to click through a couple of on-screen prompts. Doing so applies your function and displays it in your selected cell.
