Whats the reason for parentheses on my calculator?
Well, I don’t want to be dogmatic and say what the reason is, but certainly an important reason is to give priority in the order of certain operations. For example if we enter 16- 84, we’ll get 16-2 = 14. If what we really wanted was to do the subtraction first, then we can do that by writing this: (16-8)4. That’ll give us 2. Item 8, above, also deals with use of parentheses.
