RE: Evaluate expression with HP50g
Hello vini.simoes,

The easiest way is to define a function and feed it with the values you like.

Maybe you aren't not familiar with this calc. The best way is to choose in the "MODE" app:

a) RPN
b) Set exact mode in submenue "CAS"
c) Set flag 117 in submenue "FLAGS", that's important because you can access your own objects with the keys "F1" to "F6" show in the last line of display (inverted, background black foreground "white").

For example:

Your complicate expression is x^2;
Key in the following

'MYFUN(X) = X^2' Don't forget the single quotes they are important!

Then press the key "Right Shift" and then press the "SYMB", now you get the catalogue of all functions and look for the command "DEFINE" and press "OK".

Now you get a new objekt that works like a build in function.

Key in:

16

and then press where in the last line of display is MYFUN located (let's say at the fourth position), you press "F4" and you get the result you intended:

256.
