Casio FX 115 MS

Advantages: Integration and Differentiaiton features
Disadvantages: None that stand out

...This is a great calculator and is a real step up from the casio fx-83 MS which is the calculator I had previously. It has all the features of the typical scientific calculator and all the keys are in the same place as the fx-83 and the other casios. However, to make this calculator stand out from the rest is the fact that it can solve quadratic equations adn also differentiate and integrate. If you have ever had problems integrating etc. or you want to check you answers to integration/differentiation in the exam, then this calculator will find the solutions for you. At first, it isquite difficult to find the solutions quickly, although once you know how to use the functions, you'll be able to differentiate and integrate in seconds.

...This is the Casio FX 83MS Scientific Calculator, for typical use at high school level. This is what you need to keep up in maths at school at GCSE level and beyond.

There are many different versions of the Casio scientific... Read review

...will be some useful functions on these type of calculators (like solving quadratic equation and drawing out graph transformations etc.) that you cannot do on the Casio fx-83EX. But even now, at university, i still keep this calculator as it is so easy to use and has useful functions that you sometimes don't even get on the very expensive calculators! I would definitely recommend this product! Another last note is to say that to be honest, you don't even need to bother with the instruction manual as it is so simple to use and it is a commonly used calculator in schools so the teachers are bound to know how to do everything!...
