If you don't know about RPN, read a Wiki article about it (there's a link in the App that leads to the site in your language).
Instead of typing braces, you use a stack and perform operations on the stack items.
(2+3)*5 would be computed:
2 Enter (push 2 on the stack)
3 + (add 3 to the bottom stack item)
5 * (multiply stack bottom by 5)
The stack now shows "25".
RPN is much faster and easier for large, complex terms. Do yourself a favour for the rest of your life and learn postfix notation. It's easy, really.
