[ 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
Example 8.
Results equal to or greater than 10
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 [ ) ]
x
[ x10 ] 2. Be sure to enter [ x ] between the [ ) ] and [ x10

(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
When there is insufficient memory to store data
