3. Use of parenthesis
The parentheses keys are needed to cluster together a series of operations when it
is necessary to override the priority system of algebra. When parentheses are in
use on the EL-506P the symbol ( ) will appear in the display.
Calculations in parentheses have priority over other calculations. Parentheses can
be used up to 15 times in a single leve!. Calculations within the inner-most set of
parentheses will be calculated first.
