Creating Formulas to Calculate Values
After you add your data to a worksheet and define ranges to simplify data references,
you can create a formula, which is an expression that performs calculations on your data.
For example, you can calculate the total cost of a customer’s shipments, figure the
average number of packages for all Wednesdays in the month of January, or find
the highest and lowest daily package volumes for a week, month, or year.
To write an Excel formula, you begin the cell’s contents with an equal (=) sign; when Excel
sees it, it knows that the expression following it should be interpreted as a calculation,
not text. After the equal sign, type the formula. For example, you can find the sum of
the numbers in cells C2 and C3 by using the formula =C2+C3 . After you have entered a
formula into a cell, you can revise it by clicking the cell and then editing the formula in
the formula box. For example, you can change the preceding formula to =C3-C2 , which
calculates the difference between the contents of cells C2 and C3.
Troubleshooting If Excel treats your formula as text, make sure that you haven’t accidentally
put a space before the equal sign. Remember, the equal sign must be the first character!
Typing the cell references for 15 or 20 cells in a calculation would be tedious, but
Excel makes it easy to enter complex calculations. To create a new calculation, click
the Formulas tab, and then in the Function Library group, click Insert Function. The
Insert Function dialog box opens, with a list of functions, or predeined formulas,
from which you can choose.
