Hi,
I've never seen a TI95, but I am the proud owner of two HP48's and one
TI-85.

You should learn RPL especially for these realworld problems.
If it is different on the TI-95, I'd like to hear about it.
If you want e.g. x/(y+x), where x and y are given numbers, how do you
calculate it?
on the HP: x DUP y + /
You know you need x twice, so put it an extra time on the stack so
that you can use it later, after having done some stack manipulations
if neccessary.
On a TI-85:
Just type x/(x+y) and you'll get your result, but you have to type x
twice. That's very easy if x=2, but if x=1.855648896 you'll have to
be careful. The only workaround I know of is storing x in a variable
first. But the drawback of the TI-85 is that it doesn't let you use
directories, so all your variables end up together.
If there is a better way, I sure would like to hear it so I could
start using my TI more.
Bye
Andy
