Sharp EL-W531XHWHC black/white

A scientific calculator with 272 mathematical functions is a good and fully sufficient tool for high school and college students. The practical two-line display is perfectly well-arranged and allows for viewing, browsing, and editing of previous calculations. It can handle all basic, statistical and trigonometric functions, constant and chain calculations, with the possibility of editing them backwards. It is protected by a rigid plastic cover against possible falls or scratches. The calculator is in black with white elements.
