The Japanese model, with all of it's extra functions and conversions does not allow this, while the "stripped down" U.S. version allows this in solve. I like having this solve capability over the extra functions/conversions...

Have you got reliable information which model has integral and d/dx function allowed in SOLVE?
I have a DEX model, this is the most important function, I guess in a calculator, but on DEX I have problem with QR code generation for Table or Calc.

I want to decide which is better: to buy a new 991??X model or change to TI-30X Pro Mathprint?!

Thanks for any information!
