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…
