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

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.Read full review
