Enclose expressions in parentheses to have them evaluated at the start rather than during their normal order of operations. Multiple parentheses can be used inside each other.
Example: Multiplication is evaluated before addition in the order of operations, so '2+3*5' evaluates '3*5' first, then adds 2, giving 17. However, (2+3)*5 will evaluate what is in the parentheses first, so the result is 25.

In bases other than base 10 (decimal), fractional values will be rounded down.
If you click on a button and then later press the enter key for "=", the act of pressing enter might also cause the last key you have clicked on to be pressed again.
