The best calculator an engineering student can ever have.Matrix solution like inverse, determinants are very easy to solve. Differentiation and Integration can also be solved very quickly using this calculator. It handles the equations very nicely and gives the instant results.I recommend to go with 991 plus C .IT has verify,distinct root,inequality and many more "intuitive MATHS function.

best calculator

product is quite good and give answers in two different formats i.g. 3/2 or 1.5. i like his part. you can view on you tube using related query. It has more functions approx 447. Note: be careful for exams because some papers allowed the FX100 calculators only. This is not a programmable.So, in my exams may be this is allowed. I am not sure yet. light weight and two way powered makes it easy to carry and use. large graphic screen is plus point. but you have to learn a lot to run this perfectly.
