TI calculators are not RPN. I think HP made (makes?) RPN calculators.

Yeah, I'm also confused by this... the only RPN calculator I know of is the HP 15C, which is old school and not used in education.

I bought a HP50 (?) in uni to do symbolic math for some exam. It was RPN by default but you could switch.

Business courses frequently use it

Oh that is cool to know, thanks.

You still see some HP12Cs on bank trading floors.
