Reverse polish notation is better than other notation

This system is pretty shitty when written by hand.

This is true, although most people are brought up on cancerous infix and will irrationally cling to it all the way to the grave.
>latex
What the fuck does that have to do with anything? That's not the kind of notation RPN vs infix is about. RPN is a way of writing calculations where unlike infix everything is unambiguous and you never need parentheses or retarded order of operation rules.
It's also what all systems involving automatic binary operations actually use, with your infix input just being translated to RPN behind the scenes (shunting yard algorithm), because programming in terms of RPN is a super-sensible stack based approach while infix is a convoluted mess.

Check out the “Retro 15C” app for the iPhone if you like the calculator in Op’s pic. It’s awesome and free.

It's good because when retards try to borrow your calculator they soon realise they cannot operate it. Then they leave it alone.

it is pretty sweet. No more need for parentheses or stupid operator precedence tricks under RPN or PN.

They can handle it, it's just that anyone writing anything important will write it in RPN and let the shunting algorithm handle translating from brainlet infix to sensible RPN because doing otherwise needlessly overcomplicates your program with retard infix logic.

That's probably why no mathematicians use paranthenses in their publications. Just makes it so much easier to do everything in RPN in your head, right?

I don't wanna have to think about punching numbers into a shitty calculator, so let me just copy whatever I have on the paper exactly and I'm happy
