AMAZING CALCULATOR
Am currently doing a Maths course and this calculator is fantastic. Has been particularly helpful in helping me brush up on my fractions. Has many more functions than I will ever need. But am SO glad I got this. CAN be a little confusing when the answers get displayed. But if you remember to press the "SD" key (located above the "DEL" key), this toggles the answers. For example, for doing fractions, the answer may be 0.5, OR 1/2 when toggling between the two by pressing the "SD" key. Also, if you wish to change an improper fraction into a proper fraction simply press "Shift" then the "Fraction" key and use the arrow keys to key in the numbers in the upper or lower space on the fraction problem. The press "=" and then toggle the "SD" key and you see the Proper/Improper fraction. Depending on the light conditions, there is a contrast setting where you can increase/decrease the contrast. Lots of conversions available, such as; Mile-KM, Yd-M, etc. The list of conversions is shown on the inside of the detachable case. An amazing calculator. Best I've ever had. Would recommend without hesitation.Read full review

Casio Calculator FX-991ES
I liked this calculator a lot. The only problem I had was to see it closely because the picture wasn't of high quality. But after all this product arrived successfully and i'm still using it till 1 minute ago lol! It is very easy to use and it helps you with all type of sums from complex integrations till normal calculations. It's display is natural too which helps you to understand how to key in the equations. The only problem I've had was till I got used to it. It has a lot and a lot of functions and I didn't still use half of them lol. Francarl

Amazing calculator, many functions
As an A level maths student, I wanted to upgrade from my Casio fx-83GT Plus to this model as my friends had all recommended it. I definitely do not regret it, this calculator is able to carry out integrals and solve quadratic equations. It has all the functions I could need at this level and works brilliantly.

Casio FX-991ES Scientific Calculator
I needed a replacement for my FX-451M which provided easy base conversions, particularly decimal to hexadecimal and back. The FX-991ES has this capability, but only in a mode which, once selected, will only operate with decimal integers. Nobody expects the fractional part of a decimal number to be retained through a conversion to hex, but the requirement to change to a different mode (with no retention of previous results) in order to perform 'normal' decimal calculations is a severe restriction.
