Have a calculator for the university needed which can not calculate matrices or integrals. The Casio FX85 GT Plus all necessary functions (also e + x!) And also looks great;) Keys is on familiar Casio-type ... Super I find that automatically breaks are issued, the SD button then converts to if desired. Large display, which also accommodates long, complicated calculations, which can then be checked at any time. The manual from Casio brings me frankly not right on, because I can not find so easily the desired operations of fact not. As has a small beiligende instructions by the seller super Calcuso helped (a few brief explanations of key features).
