Dennis Gallagher calculator tops back-to-school supply lists: Kenny Be's Fotochop Friday
Denver City Auditor Dennis Gallagher calls himself an "independent-minded watchdog" of the city's budget. The Gallagher Calculator can do all that and then some. This sturdy finger-powered device can display the results of complex real-world calculations in three dimensions, which makes it easy for students to visualize and understand the results produced.
One of its features is the option of using "digitech" beaded entry, a data processing system that makes inputting mistakes impossible when calculating complex equations -- and, if your ancient Chinese grandparents want to use it, you're in luck! Parents and students need not check with Denver Public Schools before buying. This calculator provides all the functionality needed for math classes and is programmable for computing post-secondary household finances.
