Point Method to Create Formulas and Functions
To build formulas and functions, use the point method. Type the equal sign (=) to
begin the formula, and then use your movement keys (mouse or keyboard) to
select the cell you want to reference. Notice that the cell address now appears in
the formula bar. Type the next operator (+, -, /, *, etc.). You may then move to the
next cell you want to reference. Repeat this procedure until you have built the
formula you want, then press <ENTER>.
For functions, you may also use the point method. Type in the function name and
opening parenthesis [e.g., =SUM(]. Select the first cell of the range of cells that
you want to sum. That address will appear in the function [e.g., =SUM(A1]. Click
and drag on the desired range of cells and the range will appear in the formula bar
[e.g., =SUM(A1:A10]. Close the parentheses and press <ENTER> [e.g.,
=SUM(A1:A10)].
NOTE: Each time you select a cell or range of cells, a marquee will appear
around the selection, illustrating what range will be used in a
formula.
AutoSum Button ()
Use the AutoSum button on the toolbar to enter the Sum function. Select the cell
in which the Sum function will appear. Click once on the AutoSum button ().
Text
Text is all other data entered in a spreadsheet and is usually used to describe values.
Excel determines that data is text if the first character of the data is a letter of the alphabet
(except dates; refer to the “Dates in Excel” section above.)
