the range specified.
(2) You attempted to divide by 0.
(3) When your input values exceeds the allowable
input range of function calculations

Basic Calculation

Use the COMP mode for basic calculations.

Arithmetic calculation

• For negative values, press [ (–) ] before entering the value; You
can enter a number in mantissa and exponent form by [ EXP ] key.
See Example 6.
• Arithmetic operations are performed by pressing the keys in the
same sequence as in the expression. See Example 7.
