Casio 10-Digit LCD Portable Solar-Powered Calculator (Silver)

The Casio SL-310SV is a portable calculator built for quick, reliable calculations wherever work takes you. It presents numbers on a bold 10-digit LCD that stays easy to read from nearly any angle.

A dual power system captures ambient light through a solar cell and falls back on a battery when lighting is limited, so your workflow never pauses. This flexibility makes the calculator a dependable companion in offices, classrooms, outdoor kiosks, and trade shows.

The body features a design that is both slim and lightweight. It slips into a pocket or notebook without adding noticeable bulk, and an included wallet-style case shields the keys and screen during transport. A metal faceplate reinforces the front, so the device resists daily bumps and scrapes.

Built-in functions for profit-margin percentage and square root let vendors, students, and travelers reach common results faster. Whether you are setting a selling price, verifying homework, or splitting a dinner bill, a single key press delivers the answer.

An auto power-off feature activates after ten minutes of inactivity, conserving energy and ensuring the calculator is ready when you need it next.
