This calculator uses RPN (reverse polish notation) not algebraic notation.
If say you want to calculate 12+13, you proceed as follows
12 [ENTER] 13 + : the claculator displays 25
12 [ENTER] 13 x : displays 156

Also if you use a function like sinus or cosinus
12 [ENTER] cos displays the value (depending on the angle unit you are using).

I think you need to read a little more on the RPN before you get accustomed to this way of doing thing. The best reference is your calculator Getting started manual.

Hope it helps.
