The Calculator
The Calculator is a standard four-function calculator you can use to add,
subtract, multiply, and divide numbers. You can find the Calculator in the
Utilities drawer on the Workbench.
Opening the Calculator
You open the Calculator by selecting its icon, then choosing Open from the
Workbench menu. When you do, a window for the Calculator appears.
The Calculator Keys
In the Calculator window, each of the Calculator's "buttons" is a gadget.
When the Calculator window is selected, there are two ways you can "press a
button" :
• Select
the gadget by pointing within it, then clicking the Selection button
on the mouse.
•
For all but the < - and + - "buttons," type the character or characters
shown in the gadget. For example, you can clear the current entry by
pressing
the C key on the keyboard, then the E key.
The buttons for digits, the decimal point, and addition and subtraction are
the same as those on other calculators. To multiply, use the • button. To
divide, use the / button.
Selecting the CE button clears the current entry, while selecting the CA
button clears the current entry and any previous entries.
Pressing
the + - button changes the sign of the current entry. If the current
entry is a positive number, it is changed to the negative number that
corresponds to it. If the entry is negative, it becomes positive.
