HP DX-CAL-937-BLACK Desk Calculator 12-Digit LCD Dual Power Black

Desk calculator for everyday math

The HP DX-CAL-937-BLACK is a 12-digit desktop calculator designed for office, home and school use. It runs on dual power with a solar panel and an AA battery backup, and it switches off automatically after about six minutes of inactivity. The large angled LCD makes numbers easy to read, while big keys and two anti-slip feet help prevent mistypes during fast entry.

Upgrades from basic four-function models

This unit adds memory keys M+, M-, MR and MC plus a grand-total GT function, a backspace key and a mark-up MU button for quick percentage work. The jump is worth it when you regularly chain calculations such as 3×3+2×5-2×3 and want a single recall to show 13, or when you need instant mark-up results like (4+32)/32×100 without re-entering figures.

Suits students, cashiers and light office work

The compact 5.9×4.7×1.6 inch footprint and 4 oz weight keep desks clear and travel light. Buyers who need scientific functions, programmable macros or a two-line display should look elsewhere, as this model stays focused on arithmetic and basic financial shortcuts.
