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.

Casio Scientific Calculator fx 991ES PLUS

Great product and cheapest in the market. I want snap deal to give an option of delivery timing because most of the time the delivery is done in noon time when most of the working couples are work. This causes delay in delivery and inconvenience to both the shipper and the per who have ordered the product.

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.

This calculator is a perfect companion for engineering students. Its natural display makes it the best scientific calculator in the market.It is the most light weighted calculator of 991 series. It has fallen down couple of time from my hand but was not damaged at all. Its actually a perfect calculator for every student, there is no mathematical problem which can't be simplified using this masterpiece. Go for it without any second thoughts cause this calculator can beat any other calculator in this price range in the aspects interface, weights, looks, keypads , simplicity ,and strength .
