The Sharp EL244WB is a pocket calculator for professionals who do their arithmetic away from a desk. A modern white finish and a mirror-surface acrylic panel front an extra-large 8-digit display, and the durable plastic keys are big enough to use one-handed on a counter, in a stockroom or on a site visit. Automatic tax keys apply a stored rate rather than making you key one in each time, and a percent key covers margins and discounts. Three-key independent memory holds a running subtotal separate from the main calculation, and an extra-large plus key speeds repeated addition. Automatic power down protects the cell between uses. Twin power runs it on solar with battery backup, so any lighting will do.
