How to use parentheticals in a scientific calculator?
If your scientific calculator has them (and most of them do), press each parenthetical in the order you want it to be used. The calculator will base it's answer on the order of operations where the stuff inside the parenthesis would be evaluated first, if placed inside the parenthesis correctly. If you try to place the ending parenthesis before the starting parenthesis, the calculator should give you an error - making sure that you start again with the correct sign. Each scientific calculator has the parentheticals in a different spot, but your owner's manual should tell you where to find them.
