• You can perform arithmetic calculations by inputting expressions as they are written. All of
the example calculations shown below are performed using the
soft keyboard, unless
noted otherwise.
• To input a negative value, tap
or
before entering the value.
• The order of operations is followed when a calculation consists of mixed arithmetic
operations (multiplication and division are given priority over addition and subtraction).
• The example calculations are all performed using the Decimal mode. Using the Standard
mode causes results to be displayed as fractions. For details about the Decimal mode and
Standard mode, see “Status Bar Mode Indicators” on page 2-1-4.
