# EXCEL
### Using the Formula Wizard
**Step 1:** Click in the cell
where you want the result of the formula to be placed. Now click on the =
sign in the formula bar.
**Step 2:** Select
the function you wish to use by clicking on the drop-down arrow to the left of
the formula bar (next to the word SUM in the diagram above).
If you cannot see the
function you require, click on the **More Functions...** option at the bottom
of the list to display a window showing all the available functions:
**Step 3:** When you
have selected the function, the formula wizard provides a window to help you
complete the arguments (expressions in brackets) after the function so that Excel
calculates the right result.
**Step 4:** For an
aggregate function like the SUM function you need to select a range of cells to
add together. Click on the red icon at the right-hand end of the **Number
1** box and highlight the range of cells you want to add together.
**Step 5:** You will
see the range you have highlighted (A2:A6 in this case) appear in a box at the
top of your worksheet, there is a red icon at the right-hand end of this
box. When you have selected the correct range, click the red icon at the
right-hand end of the box to return to the formula wizard. If you make a
mistake you can delete the range from the box and highlight the cells again
before clicking the red icon.
**Step 6:** You are
now returned to the formula wizard window as above. If you need to
complete other arguments you will have to repeat the procedure above for each of
the boxes in the formula wizard. If you do not want to click on a cell to
enter a value (e.g. for a criterion in an IF function) you can type your own
value in the box. Functions like SUM and AVERAGE provide two boxes to fill
in initially, this is in case you want to add or average the numbers in two
different ranges, you would enter each range in a different box. Just
because there are two boxes does not mean you have to use them all, if you only
complete one box Excel will only apply the function to that range.
An example of the
result of your formula is shown at the bottom of the formula wizard window and
you can see the final formula in the formula bar at the top of the screen.
If you are happy with your formula, click the **OK** button.
**Step 7:** Your
formula has been completed and you should see the result in your spreadsheet as
below. If you click on the cell containing the result you will see the
formula in the formula bar.
If you want to see the
formulas displayed in your spreadsheet (e.g. so you could print them out), hold
down your **CTRL** key and press the **`** key at the same time (the ` key
is to the left of the number 1 at the top of the keyboard). Alternatively,
you can click on the **Tools** drop-down menu, choose **Options**, click
on the **View** tab at the top of the window and click to place a tick beside
the word **Formulas** in the Window options section. You will now see
the formulas displayed. To display the results of the formulas again
either press **CTRL** and **`** or return to the** **Options window and
remove the tick beside Formulas in the View section. The diagram below
shows formula display turned on so our formula is displayed.

return to the Excel index.**
