The Sharp EL334W is a desktop calculator for business professionals at home or in the office, built around an XL 12-digit LCD that stays legible across a desk. A kick stand sets the display angle to suit how you sit, and non-slip rubber feet keep the body planted during fast entry. Cost, sell and margin keys turn profit margin work into a direct calculation instead of a chain of percentages, and tax-plus and tax-minus keys plus a grand total function cover invoicing and end-of-day totals. Percent, double zero and sign change keys handle the rest of the daily arithmetic, and a four-key memory holds a running subtotal. Twin power runs it on solar with battery backup.
