Actually:

2 5 8 5 - x +

10 keystrokes

I use RPN on my phone calculator for fun but it can also be annoying sometimes.

On my CASIO FX-260 Solar II calculator (super cheap, really nice and simple but also powerful) that would be:

2 + 5 ( 8 - 5 ) =

9 keystrokes

You could do

8 <enter> 5 - 5 × 2 +

-> 8 keystrokes

8 5 - 5 * 2 + CR .
