It is possible to go on different routes, for example: A) Develop a CAS with High School and university first year math "usual" answers (I call this Fake CAS) B) Develop a CAS that unusable for the poor undergraduate student with no Thesis in CAS building thus making the CAS unusable to anyone else except for specialists C) Balanced CAS  somewhere in between the extremes The main problem is that you can't please everyone. One solution would be a specific CAS settings application  if HP likes the idea  where all these requests would be gathered along with additions to the [Help]. Who pays for this? Who has the time to develop, test, and maintain it? Will it bring HP an advantage in the market? Without it would HP Prime be consider somewhat inferior to, say, TINspire CX CAS (which I also own both in a PC and physically) I think HP should be superior in every way and since many people here point out errors/incompleteness/different behavior they still should be taken as a positive feedback and considered seriously. Not every (old) High School teacher have the capability to explain CAS quirks to students, therefore I strongly recommend you consider adding for the user (teacher/student) to optionally "stupefy" your CAS even if you thing that for higher math the result is wrong. On the other hand this would IMHO require feedback from the educators in France. How to make Giac, KhiCAS, GeoGebra, HP Prime CAS, more user friendly? I'm again talking about high school level math (or first year university). What about HP? Tim Wessman? VPN
