Bad video, using know bug on expand function to try a put HP bad reputation. Try not use expand function, HP will simplify AUTOMATICALLY AND almost instantly!!
Indeed, both A and C revision are 3 times faster than D. If ran more than once on my D revision here, it takes more than 90 Seconds! I doubt this bug will ever get fixed.
Yes, in some algorithms, certain calculators can outperform others, but overall, in terms of other functions and the majority of tasks, the HP Prime will outperform all others.
If you simply put the expression without using the expand command, then it'll give you the right answer in just a sec, which is very weird. If yours is faster when using the expand command, then we must have different expressions.
