SLEEK AND FAST

I used to have a Casio 9FX Caculator during my college days as most of the other students had. There were two versions of the Casio calculator and the cover used to break by the time you moved to Second year. The richer ones among us used to sport the trendy ones from Texas Instruments. Come to think of it the Calculator was called Calci during those days. I am not sure whether the same slang persists now or not.

Anyway coming to the product the updated FX991MS model from Casio is the best of the lot. The cover is a slider type and can fit as top cover or can be used for support as bottom cov

GREAT CALCULATOR OF CASIO [B.TECH]

This product is a nice product. Let me mark first, it has the best sleek outlook out of all the models of CASIO.

It has a lot of functions. The most useful are-
1. Trigonometric Functions
2. Logarithmic
3. Factorials
4. Permutation/Combinations
5. Solving Equations
6. Definite Differential+Integral Calculus can be solved
7. Complex no. form
8. Matrix
9. Vectors
10. And lot more.
It has a life of 17000hours[the battery] which is 708 days of continuous i.e. 24x7 which is quite impossible.
The service of Flipkart and its reliable original product will give you 7long years of faithful service. Th

The best and most eonomical choice for any science student

I have been using this for the past year and it has worked perfectly.
The form factor is just amazing. It is very thin and light as compared to the ones available a few years back. The solid cover is very useful as it prevents the calculator itself from getting damaged. It has everything that a science as well as engineering student will ever need (to do on a calculator ;))

This does not have the notebook display, which however, i dont feel is very helpful. If you plan on using this calculator for a long time then have a look at FX991ES as well before purchasing (the only difference is the d

Excellent Scientific Calculator

Haven't bought this from flipkart, but from the market. Price at flipkart is very good.

Pro: Good build quality. 2 line display, both lines quite large and legible. Reasonably large buttons for easy use. Runs on LR44 cell as backup when light is not sufficient for solar panel to work. Very sleek. Scroll up-down to look at previous calculations. Speedy processor (I use 69! - 69 factorial - as a good calculation to check speed in any calculator).

Con: Very few and probably very minor. Just would have liked more previous calculations to be displayed (limited to previous 11 in standard mode, 6 i

A good Calculator for Engineers

I am an Engineering student and I bought this calculator when I was in 12th standard. I have used the calculator for 5 years now seamlessly and is still in good condition without any need for battery replacement. This calculator is ergonomic and is highly functional in performing calculations varying from different mathematical domains. Highly useful and a must buy for engineers and engineering students.

First to review

Review after using the calculator over 6 years

I have used the calculator since 2004.That time it is the best calculator available at Kolkata. It has almost everything but now-a-days you get more better calculator with graphic display. So, I don't think anyone like to buy this calculator.
