Parentheses calculations

Operations inside parentheses are always executed first. SR-281N
can use up to 13 levels of consecutive parentheses in a single
calculation.
Closed parentheses occurring immediately before operation of the [ ) ]
key may be omitted, no matter how many are required.
2 x { 7 + 6 x ( 5 + 4 ) } = 122
2 [ ( ] 7 [ + ] 6 [ ( ] 5 [ + ] 4 [=]
(Note) : A multiplication sign " x " occurring immediately before an
open parenthesis can be omitted.
The correct result cannot be derived by entering [ ( ] 2 [ + ] 3 [ ) ] [ EXP ]
2. Be sure to enter [ x ] between the [ ) ] and [ EXP ] in the below
example.
2
( 2 + 3 ) x 10 = 500
[ ( ] 2 [ + ] 3 [ ) ] [ x ] [ EXP ] 2
