Instructions
All operations
and functions placing characters into the display window can use the screen
displayed keys or corresponding keys on the keyboard of your computer;
just click on the display window prior to entering characters from the
keyboard.
- The number
keys 0 through 9 are for data entry, as is the decimal button.
- The other
keys are function keys and operational keys.
Operations:
- + is
to add
- - is
to subtract
- * is
to multiply
- / is
to divide
- % yields
a percentage (multiplies the answer in the display window by .01, the
same as dividing by 100).
Functions:
- +/- is
to negate the answer. (Negation is the process of multiplying any number
by -1.)
- The =
key gives a final answer.
- C clears
all operations and the answer area is reset to 0, while <— clears
only the previous keystroke entry; it is the equivalent of backspace
on the keyboard.
Note: The
operational key acts on what is displayed with the number entered after
it. For example, to multiply 5 by 2: click 5, click *, click 2, click
=, for the answer 10.
