The Sharp EL510RT solves science, engineering and mathematics problems without making you translate them first. Direct Algebraic Logic shows the equation as you enter it, in the order it appears on the page, so what is on the display matches what is in the textbook. A large 10-digit single-line LCD returns results to 10+2 digits, and 169 functions across normal and statistics modes cover general maths, science and trigonometry coursework. Three key memories, last answer recall, and playback and editing buttons let you step back through an entry and correct one term instead of starting again. Twin power runs it on solar with battery backup, and the included hard case protects it in a bag between class and work.
