OPERATORS
You can use your Plus/4 like a simple calculator Besides the standard
+ and - signs, your Plus/4 uses the 'sign for multiplication and the /
sign for division and fractions. (Computers use the * sign instead of an
X (or multiplication because a computer can't tell the difference be
tween the letter X and the mathematical symbol x.) You can use these
operators and numbers in direct mode (no line numbers) or in a pro
gram. Neither numbers or operators should be in quotes for your Plus/4
to perform mathematical operations.

NOTE; Your Plus/4 doesn't accept commas as part of a number.
For example, you must type 109401 instead of 109,401. If you put
a comma in a number, your Plus/4 thinks you mean two numbers
(separated by the comma), so your Plus/4 would read 109 and
401 instead of 109401.
You can write a fraction like this: .5
or like this: V2 Your Plus/4 is
actually performing
the division
If you put a fraction in a PRINT statement, your answer is always
returned as a decimal or whole number. For example:
PRINT 139 493
5.28194726
RETURN
Here's an example that uses pi (3.14159256...), which represents the
ratio of the circumference of a circle to its diameter. Use this value by
just pressing the 77 key
PRINT 77, 374
B.39998036E-03
RETURN
