Calculations With Parenthesis; Coordinate Conversion - Citizen SR-135N Anweisungshandbuch

4. Calculations with parenthesis.

Parenthesis are used when it is desired to perform calculations in a
first priority that usually followed for the +, –, x,
operations. In other words the "(" ")" force those prior operations it
to be pending until the calculation inside the parenthesis are
performed.
Parenthesis may be used in a chained calculation as long as the
total of levels ending due to the automatic priority Logic and
parenthesis does not exceed 15.
