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
same sequence as in the expression. See Example 7.

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.
