HP35s simple query about stacks

[Kyburo]

Thanks for your replies everyone, helped clear that up for me!

I'm in the funny middle ground of using brackets and having to cursor sideways (on the casio) now seems very annoying, but still not 100% confident with myself remembering to hit every RPN keystroke in the correct order when coming to complicated calculations.... But I'm certainly getting there!

Totally side question - I'm also soon to start working with MATLAB, I've picked up a somewhat dummies guide to it also as I've never used it but I was wondering if that also works in an RPN fashion or just ALG? If anyone knows
