Starting the Calculator

To start the Calculator from the main SCO Shell menu, select:

Application → Calculator

You can use your terminal's numeric keypad as well as the number keys in the keyboard's top row. (If the keypad keys do not seem to work, try pressing <Num Lock>.)

For example, type: 2 + 4 + 6 =

There is no need to press <Space> between numerals. When you finish, the Calculator looks like this:

The display acts just like the one on a pocket calculator. You enter asterisk ``*'' to multiply numbers together (this is equivalent to the ``×'' key on a pocket calculator). The Calculator keeps a running total of the calculation until you reach the end. (If you want, you can press <Enter> instead of the ``='' character; they both do the same thing.)

The tape keeps a record of the whole problem, just as you entered it. The answer does not appear there until you press =, just as on an adding machine tape. The arrow keys let you rewind the tape to take a look at the calculations that you did earlier.
