## Description

Buy Casio fx-991EX Classwiz for High School Students by Getling, David (ISBN: 9781548247102) from desertcart's Book Store. Everyday low prices and free delivery on eligible orders.

Review: Very solid and good quality. - Bought this for my son doing GCSE maths- and he will be doing maths at a level- so bought this rather than a cheaper one and then having to buy another one when he gets to a level. So many functions and you can print out instructions for the complicated actions from the website. Very solid and good quality.
Review: The fx-991EX does so much, and this guide is really helpful in pointing out its capabilities - A great accompaniment to the calculator my son's school told us to get for his maths A Level. I'm not convinced that most maths teachers spend time explaining how capable modern calculators are, and the instruction manual that comes with the calculator is pretty perfunctory, so a more detailed step by step guide like this is super helpful in illustrating what's possible.

*by A***F on 5 April 2018*

Really good except daughter is doing Further Maths and there are a couple of functions not included - inverse poisson and chi squared. Absolutely perfect for the Maths A Level though and this is the preferred calculator when these functions are not needed as its simpler to use.
