Learning Resources 12-digit dual-power calculator

The Learning Resources 837-BLUE is a desktop calculator designed for students, office workers and home users who need reliable everyday arithmetic. It runs from a solar powerboard in bright light and accepts one AA battery for continuous operation in dimmer conditions. The 12-digit LCD shows large numbers that are easy to read from a distance.

ABS plastic body with big buttons and angled display

The unit measures 5.7 x 4.7 x 1.8 inches and weighs 4 oz, so it stays put on a desk without taking much space. Large, well-spaced keys reduce entry errors during long sessions, while the tilted screen improves visibility whether you are sitting or standing. A single AA battery compartment is accessible on the underside.

Solar-first power with auto-off after six minutes

In normal indoor lighting the solar panel supplies all the energy the calculator needs; the battery only takes over when light is low. Power draw is negligible, so a fresh cell lasts months. The auto power-off function shuts the device down after about six minutes of inactivity, preserving battery life without any user action.
