Casio Large Display Solar & Battery-Powered Calculator (Green)

The Casio SL300VC-GN is a pocket-sized calculator designed for anyone who moves between a desk, a classroom, and the checkout counter. It combines solar power with a built-in battery, so you can add numbers in bright light or under a desk lamp without worrying about downtime. The eight-digit display is larger than what you find on many small calculators, making each figure clear at a glance.

Built-in functions for tax, time, and profit margin shorten everyday business tasks like adding sales tax, working out billable hours, or checking mark-ups before a customer pays. An independent memory keeps running totals safe while you shift between calculations, and the durable plastic keys stand up to rapid data entry without sticking or fading.

At just 118.5 by 70 by 8 millimeters and only 50 grams, the calculator slips easily into a shirt pocket, pencil case, or cash drawer. The green finish makes it easy to spot in a busy workspace or a packed backpack. Whether you are a small-business owner reviewing receipts, a student finishing homework, or a traveler converting currency on the road, this model delivers quick, reliable results without occupying much space.
