best HP scientific calculator

[Tugdual]

I would still recommend a 50g over a35s; 50g has a multiple equation solver which is very convenient for scientific calculations and the 35s has nothing approaching. Working with matrices is by far simpler with the 50g and the 35s doesn't fully support complex numbers. Unit of measurement is also restricted to common conversions on the 35s while the 50g had a complete support quite easy to use with function keys (easier than the prime). In terms of programming RPL is very advanced and in my opinion easier to understand and maintain than key codes on the 35s.
The 35s was an unexpectedly valid replacement for the 15c but the 50g is definitely in a different league. Since I acquired the 50g, all other machines are taking the dust.
