Apple Keynote '08 - Manual (Page 141)

Chapter 7 Using Formulas and Functions in Tables 141
Here are the basic arithmetic operators. For complete information about arithmetic
operators that Keynote supports, see “Understanding the Arithmetic Operators” on
page 141.
To add an arithmetic formula to a cell:
1 Select an empty cell for displaying the results of the formula.
2 Open the Formula Editor. For example, type an equal sign (=).
3 Enter the formula in the text field following the equal sign.
For example, to enter the formula A3 * B5 + B6, in the text field following the equal
sign you could click or type A3, type * (the multiplication operator), click or type B5,
and then click B6 (if you don’t type an operator before clicking, Keynote adds the plus
sign (+) automatically when you’re not specifying function arguments).
4 Click the Accept button or press Return or Enter to save the formula.
Understanding the Arithmetic Operators
Arithmetic operators in table cell formulas perform arithmetic operations and return
numerical results.
Here are the arithmetic operators (examples presume that cell A2 contains 20 and
that B2 contains 2):
m The operator + returns the sum of two values.
For example, A2 + B2 returns 22.
m The operator – returns the difference between two values.
For example A2 – B2 returns 18.
m The operator * returns the product of two values.
For example, A2 * B2 returns 40.
m The operator / returns the result of dividing one value by another value.
For example, A2/B2 returns 10.
To perform this operation Use this arithmetic operator For example
Sum two values + A2 + B2
Subtract one value from another
value – A2 – B2
Multiply two values * A2 * B2
Divide one value by another
value / A2 / B2
