The Sharp ELW535XGWH is a twin-powered scientific calculator built around Sharp's WriteView display, which shows calculations entered and displayed as they are written on paper. A large 16-digit, four-line LCD gives room for a full expression and its result, so fractions and exponents stay in their proper form instead of being flattened into a single line. Its 422 functions run across three modes — normal, statistics and drill — with drill mode generating practice problems rather than only solving them. One- and two-variable statistics are covered, and eight temporary plus four definable memory buttons hold intermediate values. Suited to general maths and science, pre-algebra, algebra, geometry, trigonometry, statistics, biology and chemistry. Gloss black with white accents; hard case included.
