Error conditions

Error message will appear on the display and further calculation
becomes impossible when any of the following conditions occur.
Indicator
Math ERROR
Syntax ERROR
Stack ERROR
Argument ERROR A function does not have the correct number of
Non simplifiable When the value you specify is invalid as divisor
Insufficient MEM
Error
To release the above errors, please press [
error, or press [ AC ] key to cancel your calculation, or simply press
[ ON ] key to reinitialize the calculator.

Basic Calculations

Use COMP ( [ MODE ] 1 ( COMP ) ) mode for basic calculations.

Arithmetic calculation

Arithmetic operations are performed by pressing the keys in the
same sequence as in the expression. See Example 7.
For negative values, press [ (–) ] before entering the value.; You can
enter a number in mantissa and exponent form by [ x10

Meanings
(1) You attempted to divide by 0
(2) When allowable input range of function
calculations exceeds the range specified
(3) When result of function calculations
exceeds the range specified
(4) When specifying an argument to a function
outside the valid range
(1) Input errors are made, ex. improper syntax
(2) When improper arguments are used in
commands or functions
When a calculation expression exceeds the
capacity of the numeric stack or command
stack, ex.
When the [ ( ] key is used more than 25 levels
in a single expression in linear mode
