CAS: (2^10)! is undefined?

This is probably not a coincidence that all calculators CAS were outsourced (well, except for the HP28/48 symbolic engine, but it's symbolic capabilities were very limited). Another thing to keep in mind is that most components of the CAS are highly interdependant, a small change in one component may have side-effects in other components (that's why regression tests based on integration are very effective), that's why I'm very conservative with any change people ask.
Probably someone can build a toy-CAS that would return answers more similar to what some teachers expect from highschools students for problems that can be solved by mental computation. But this is in my opinion a bad usage of CAS, a CAS should not be used to replace your brain. It should be used where it is more efficient than our brain, i.e. for real computations.

Totally agree!

Tout à fait d'accord!
