Overview

The Sharp EL-330WB Desktop Calculator 5-pack is designed for offices, classrooms, or homes that need multiple reliable calculators without the cost of buying them individually. Each unit features a 10-digit large angled LCD display that presents figures clearly from a natural seated position, eliminating the need to hunch over or reposition the calculator. The modern white housing keeps the look clean and professional on any desk, while the plastic keys offer consistent tactile response for quick data entry.

Beyond basic arithmetic, each calculator includes practical business keys — cost/sell/margin for quick retail calculations, automatic tax keys that can be programmed with your local tax rate, and a currency conversion function. A 4-key independent memory lets you store and recall running totals, while the extra-large plus key and backspace key help reduce input errors during repetitive number crunching. Dual power operation combines solar cells with battery backup, and an automatic power-down feature conserves energy when the calculator sits idle. Sold in a 5-pack, this set is a cost-effective way to outfit a workspace or keep replacements readily available.
