Using an HP with TI manuals

I go both ways (regarding calculators, anyway) It's also fun to use an HP manual and follow the examples with an TI. I can see both sides of the argument. If I have a written equation I want to enter, I like TI's AOS. I can type the equation pretty much just as it's written, other than having to include extra parentheses for denominators occasionally. If I'm solving a problem right on the calculator, I like RPN. That's one reason I use the HP Prime. I can have both systems on one calculator.

This is why I found the HP-28C was such a game changer when it came out. Aside from its many other capabilities, I could use algebraic or RPN entry on a problem depending on what was more clear or appropriate. It became even easier to evaluate complex algebraic problems when the HP-48SX came out with its Equation Writer. I found it ironic at the time that HP, of all companies, had created the world's best algebraic calculator.
