Using operators in formulas
After you enter a formula, the cell displays the calculated result of the formula. The
formula itself appears in the Formula bar when you select the cell, however.
Here are a few examples of formulas:
=150*.05
Multiplies 150 times 0.05. This formula uses only values, and it always
returns the same result. You could just enter the value 7. 5 into the cell.
=A3
Returns the value in cell A3. No calculation is performed.
=A1+A2
Adds the values in cells A1 and A2.
=Income–Expenses
Subtracts the value in the cell named Expenses from the value in the
cell named Income .
=SUM(A1:A12)
Adds the values in the range A1:A12, using the SUM function.
=A1=C12
Compares cell A1 with cell C12. If the cells are identical, the formula
returns TRUE ; otherwise, it returns FALSE .
Note that every formula begins with an equal sign ( = ). The initial equal sign allows Excel to
distinguish a formula from plain text.
Using operators in formulas
Excel formulas support a variety of operators. Operators are symbols that indicate what
mathematical operation you want the formula to perform. Table 15.1 lists the operators
that Excel recognizes. In addition to these, Excel has many built-in functions that enable
you to perform additional calculations.
