THE USE OF THE MINI-CALCULATOR IN THE CLASSROOM
Gus Hawco and John McGrath
A few years ago, people thought of calculators as costly, bulky machines that added, subtracted, divided, and multiplied, and were used only in business offices. With the advent of the mini-calculator in 1971 that whole image changed. Prices dropped to under $100 a unit, with some now selling for as little as $10, and even cheaper calculators may be on the market soon. These pocket-size electronic calculators are sprouting everywhere, even in the pockets of school children.
