RE: Casio FX-991EX and FX-300ES
The fx-991CE X is better option then fx-991ex, more functions and is in "magyar" (the other languages are czech, slovak and polish - CE means central europe).

This version differs a little bit compared to the fx-991de x.
CE version has periodic table, but there is no functions like product, GCD, LCM, Int, Intg, RndFix
I recommend to you try your calculations in the emulator.

I have all three calcs and all three calcs accept d/dx and integrals in the solve capabilities. Another question is how difficult is the integral or d/dx and how much the computations consume time

Following examples by using fx-991EX
solve d/dx(x^3+5x^2-2x-5)=0/x=A
A=0.189, A=-3.523

solve integral(x/sqrt(1+x^2),0,A)=19
A=19.975 after 33s,
