As the microchip revolution took root in the late 1960s, one of the most obvious uses for the new miniaturization was in the field of mathematics. Digital computers’ original tasks had, of course, been related to calculating much faster than deskbound human beings. The power of a once-massive digital computer transferred to a handheld device would allow for a revolution in calculation, allowing mathematicians of all stripes, from accountants to engineers, to free themselves from lengthy and difficult slide rule calculating…
