Casio Fx 991cex Classwiz Scientific Calculator Zilver

I bought 2 calculators online and came to the Leicester store in the following day. It is very helpful for undergraduates who are studying computer science.

This calculator is the best option for you if you are an engineering student! It can solve equations and do derivatives and integration. Even converting units such as kg to lb or ft to meter. I tried many types and I am completely satisfied with this product! Good luck!!!

Pros: -Has many features which usually only come with more expensive calculators (imaginary numbers, matrices, polynomials) -Good build quality -Low price -Fast at calculations -Easy to use menu system Cons: -Some functions and features of the calculator can be hard to learn at first -Features (such as complex polynomials) can be a long process (this could be simplified a bit better) -Cannot set some defaults (for example, defaulting to rounded decimal form instead of fractions). All answers default to fractions which can be annoying at some times Overall: Great calculator. It's fast, has lots of features and seems pretty durable. I would recommend this to others and would buy again.

I order this calculator and it only took a few days to receive it. The quality is greater than the way I thought plus the price is amazing.

I'm an electronics engineering student and this is the best calculator I've had. This is actually an upgrade from my Casio FX-991 MS. That was almost perfect and it lasted me for quite a bit but I needed to change base logs and the MS didn't allow it. This EX version is complete. I don't see anything missing aside from graphing, but then it will no longer be allowed for exams. Looks slick too. The best!
