(3) When result of function calculations
exceeds the range specified
(4) When specifying an argument to a function
outside the valid range
Syntax ERROR (1) Input errors are made, ex. improper syntax
(2) When improper arguments are used in
commands or functions
Stack ERROR 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
Insufficient MEM
Error When there is insufficient memory to storedata
or perform your calculation
To release the above errors, please press [ W ] [ X ] to correct your
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 [ x10x ] key. See
Example 8.
Results equal to or greater than 10 10 or results less than 10 –9 are
displayed in exponential form. See Example 9.

Parentheses calculations

Operations inside parentheses are always executed first. SR-270X
Math mode can use up to 24 levels and Linear mode can use up to
25 levels of consecutive parentheses in a single calculation.
Closed parentheses occurring immediately after operation of the [ ) ]
key may be omitted, no matter how many are required. See Example
10.
(Note) : A multiplication sign " x " occurring immediately before
an open parenthesis can be omitted.
The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ]
[ x10x ] 2. Be sure to enter [ x ] between the [ ) ] and [ x10x ] in
Example 11.
