This is not to say that HP engineers are indifferent to students who aren't skilled with RPN and programming. 85 Style I find the TI the easiest to use. Everything is clear, and the menu system is convenient. On error, one can goto the problem line directly for editing. Casio Style I find it interesting that the fx7300G I bought last month programs almost exactly like the fx7000g I bought in 1987.
Variable names are limited.
However, it seems to work well and quickly.
