The Sharp ELW516XGSL is the most capable scientific calculator in Sharp's non-graphing range. Its WriteView display renders fractions, roots, exponents and integrals the way they are written on paper across a large 16-digit, four-line LCD, so a student checks their working rather than decoding it. Seven modes — normal, statistics, drill, complex, matrix, list and equation — carry 640 functions, including quadratic and cubic equation solvers and a three-variable linear solver. Sixteen memory buttons in total, split between temporary, formula and user-definable, keep a long derivation manageable. It is built for general maths and science through pre-algebra, algebra I and II, geometry, precalculus, calculus, trigonometry, statistics, biology, chemistry and physics. Twin powered, hard case included.
