The Casio Solar Plus Desktop Calculator works well for either home or office use. Using Solar Plus power, the device runs on sunlight when it's available and stores extra solar energy for later on, so it can work in dim light as well. When not in use, the calculator switches off automatically. This electronic calculator includes a large display and bigger buttons and labels, making it easy for you to see the function and output that you're using. Additionally, it has an impressive list of functions available to help make your day to day computing needs a breeze. If you're in the business field, the Casio desktop calculator includes profit margin percentages, tax functions, grand total and key rollover features.
