Casio FX-991ESPLUS Scientific Calculator - SIlver

A very good, easthetically pleasing and accurate calculator as I would expect from Casio.

I bought this calculator to cover the electronic mathematical needs of a private student studying for an A-level in mathematics. I find it aesthetically pleasing and I much prefer the keyboard with light silvered background. the display is clear and the digit size is nearly double the size of the -ex classwiz! I use it regularly and every day. There are a couple, probably literally two, drawbacks with this calculator. The first is that it doesn't display a cumulative binomial distribution table. the second, which probably applies to most advanced scientific calculators today, is that its not possible to change the exponential coefficient to a negative value after it is entered. Admittedly this is not a major problem and a process that's fairly easy to remember.Read full review

Not Genuine Doesn’t work. No option for zero stars on the rating scale otherwise would have got zero.

Not a genuine product. Doesn’t work. Don’t be duped.
