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.
