Part II: Working with Formulas and Functions
Entering formulas manually
Entering a formula manually involves, well, entering a formula manually. In a selected cell,
you type an equal sign (=) followed by the formula. As you type, the characters appear in
the cell and in the Formula bar. You can, of course, use all of the normal editing keys when
entering a formula.
Entering formulas by pointing
Even though you can enter formulas by typing in the entire formula, Excel provides
another method of entering formulas that is generally easier, faster, and less error prone.
This method still involves some manual typing, but you can simply point to the cell refer-
ences instead of typing their values manually. For example, to enter the formula =A1+A2
into cell A3, follow these steps:
- Select cell A3.
- Type an equal sign (=) to begin the formula. Notice that Excel displays Enter in
the status bar (lower left of your screen). - Press the up arrow twice. As you press this key, Excel displays a dashed border
around cell A1, and the cell reference appears in cell A3 and in the Formula bar. In
addition, Excel displays Point in the status bar. - Type a plus sign (+). A solid color border replaces the dashed border of A1, and
Enter reappears in the status bar. - Press the up arrow again. The dashed border encompasses cell A2 and adds that
cell address to the formula. - Press Enter to complete the formula.
When creating a formula by pointing, you can also point to the data cells by using your mouse.
Pasting range names into formulas
If your formula uses named cells or ranges, you can either type the name in place of the
address or choose the name from a list and have Excel insert the name for you automati-
cally. Three ways to insert a name into a formula are available:
■ (^) Select the name from the drop-down list. To use this method, you must know at
least the first character of the name. When you’re entering the formula, type the
first character and then select the name from the drop-down list.
■ (^) Press F3. The Paste Name dialog box appears. Select the name from the list and
then click OK (or just double-click the name). Excel enters the name into your for-
mula. If no names are defined, pressing F3 has no effect.
■ (^) Click the Use in Formula drop-down on the Formulas tab (Defined Names group).
This command is available while you are in edit mode, and it allows you to select
from the available range names.
