BEST Calculator

I was using Casio fx991 ES earlier. This is an upgraded version of that CalC and hence it is sx991 ES Plus. >>This CalC is allowed allowed in almost all other universities as it is non-programmable. >>It is very handy to use, display is perfect and also, I can see some upgrades in simplifying Complex numbers and Vector calculations. >>Best part is its UI. Very easy and readable/Writeable UI with real life appearance. >>Equation solving, integrations, differentiations can also be done easily. >>Battery Life, Design, Look are excellent. If you're doing Engineering and want to buy a Calculator, this product is best for you.Simply Best Calculator I was using Casio fx991 ES earlier.

You gotta have a weapon you can rely on

ultimate cooolest device for an engineer \m/!! this fx 991es plus is the best geek gadget an engineering student can ever have. like its the best weapon one can carry along with them or best friend for ur examinations. I can however assure u other casio calculators are there in the market but nothing beats this particular model fx-991ES plus on the engineering battle ground. Even for the complex calculations of various roots or polynomial equations this calculator comes in handy just like a soldier's ASSAULT RIFLE in the war so it is for an ENGINEERING student during the examinations heat, where accurate values are a must. The most amazing thing it got is its display that make it so much more handy for complex problems..that is like natural display which make it more easy to use.

Perfect for electrical engineers.

I bought it and it is working wonderfully. Design is very good and display is also very large which is good. Different color keys makes easy to differentiate between many keys. I think this is the perfect and most newer model that CASIO has launched till now. And no doubt it is good looking in design compared to its previous models. Also it is thin and slimmer than other calculators.

ONE AMONG THE BEST!!!

THE CASIO SCIENTIFIC CALCULATOR Fx991ES PLUS IS THE BEST OPTION FOR SOME ONE WHO IS ABOUT TO BUY A NEW SCIENTIFIC CALCULATOR. ENHANCED WITH 400+ FUNCTIONS THIS CALCULATOR IS THE BEST CHOICE FOR THE ENGINEERING AND HIGHER MATHEMATICS STUDENTS (ME MYSELF IS A MATHEMATICS STUDENT AND MY BROTHER IS A ENGINEERING STUDENT). SPECIAL FEATURES *FUNCTIONS LIKE INTEGRATION DIFFERENTIATION LINEAR EQUATION SOLVING ARE EASILY DONE. *THE DISPLAY IS GOOD AND IS VISIBLE FROM EVERY ANGLE. *RESULTS ARE SHOWN EITHER IN THE FRACTIONAL FORM OR IN THE DECIMAL FORM(THE CONVERSION IS POSSIBLE). CONCERNS *SOME EXAMINATIONS DO NOT ALLOW THE USE OF Fx991ES MODEL CALCULATOR FOR THE ARE PROGRAMEABLE.(HIGH SCHOOL AND SECONDARY SCHOOL STUDENTS PLASE GIVE ATTENTION) *THE LABELING ON THE BUTTONS ARE NOT DURABLE. *SOME ITEMS HAVE THE PROBLEM WITH BUTTONS AS RECKLESS USE RESULTS IN THE BRAKEAGE OF BUTTONS. IN SHORT THIS IS A FINE PRODUCT FROM THE CASIO COMPANY REGARDING THEIR PRICE AND QUALITY. THIS IS REALLY GOOD GADGET AND I RECOMMAND THE SAME FOR SOMEONE LOOKING FOR A SCIENTIFIC CALULATOR.
