Item: 365910 Model: SE-230110E
The Sustainable Earth by Staples SE-230110E Calculator set features a 100 percent recycled casing, making it a great choice for environmentalists. The casing is constructed from materials previously used for ink and toner cartridges. It relies entirely on solar energy for power, eliminating the need for a battery. The angled screen allows you to easily view the 8-digit display while typing on the calculator. The device shuts off automatically when not in use, saving energy and ensuring the device's longevity.
Quickly Determine Key Figures
The SE-230E has clearly labeled buttons that allow quick calculations involving addition, division, subtraction, multiplication, and the determination of square roots. A single button controls the use of positive and negative numbers, and a different button lets you enter percentages, allowing you to easily input figures involved in profit-and-loss calculations, margin-and-markup formulas, and inventory tracking.
Three-Button Memory Functions
The calculator provides three buttons that allow you to quickly enter a single figure for storage or easy manipulation. The memory plus (M+) button lets you add to the stored number, while the memory subtract (M-) button reduces it. Memory recall and memory clear are on the same key (MCR), and this button lets you quickly access a stored number or start over with a new figure. Those looking to keep track of multiple figures or create a paper trail of their calculations may want to purchase a pack of Staples Sustainable Earth Perforated Writing Pads.
Bonus Pocket Calculator
A miniature calculator with similar features comes with each purchase of this bonus pack. The smaller SE-110E calculator has a miniature display and can be turned off with the push of a button.
