The Play/Stop key can be used to check the currently entered number or
the end result.
22.2.3. Entering a calculation.
The operation of the calculator is very simple. In outline, enter a number,
followed by an operator, followed by a number, and so on until all the
required calculation has been entered. When you want to hear the result,
press the Enter key.
In addition, the following points should be noted:
• The normal precedence order for the four arithmetic operators can
be disregarded. The calculation will be done by the order in which
they are input.
• The calculator accumulates results, so your next mathematical
operation can use the previous result.
• The maximum number of digits that can be input in one number, is
12.
• The maximum number of digits in the result is 12.
• The least significant digit is rounded down.
22.2.4. Clearing the calculator memory.
After entering a calculation, to clear the calculator memory, press the
Cancel key. PLEXTALK will confirm that this has been done by saying
"Cleared".
NOTE: Using the Clear function, with the use of the Cancel key, will clear
the entire calculation and not just the last entered number.
