Help in choosing a new calculator

[Jlouis]

You can set the 50g to algebraic and it will do whatever you want.

But if you mean you didn't like the program language, which is RPL, maybe you can try the HP 35s, set it to algebraic and the keystroke program for it is not difficult, although I don't know if it compares to the HP 27 you are used to.

Another option is find a HP27s, it has a powerfull algebraic solver and if think it has 7kb of memory, but it is a little bit hard to find ( only used in auction sites) and more expensive than the 35s.

Good luck, and keep us informed of your search.

Cheers
