jan 1, 1954 - 1954: First prototype of desktop calculators

Description:

As a former student I can say that calculators have saved my exams on more than one occasion, not only by learning how to spell the word “pocket” with numbers on its small screen, by giving me hours of fun while others were doing the written test, but also because they helped me hide a lot of cheat sheets on its back and cover.

Back in 1954, IBM presented the world’s first electronic calculator in the United States, made with transistors, something highly revolutionary and technological for the time. It was quite large and could cost around $80,000. But, after a short time, more commercial models were launched, which thanks to the development were more reliable and affordable.
