Product details:
The government-approved FX-83GT Plus from Casio is approved for use in UK school examinations. Perhaps this is why it is the top selling calculator in the country. More likely its the intuitive user interface and the huge variety of functions available. With a VPAM display that shows workings in the same way as your school textbook and a strong case to prevent it from getting bashed about in your bag this is the perfect choice for accuracy and reliability.
