Casio ClassWiz fx-83GT CW Scientific Calculator - Black. This is new but the box is slightly damaged. it is a genuine Casio calculator (many on eBay are counterfeit!) and it can be checked - universities will check before you go into exams needing a calculator. This version can be used in GCSe maths and would be helpful for someone on the higher paper. You can use it to find LCM/HCF very quickly and to check/calculate things like quadratic equations. it's good enough for A level and University. My son used this version in his economics degree at Cambridge.
