It couldn’t multiply or divide. He then went into the arithmometer, which is arguably the first commercially successful mechanical calculator with four functions. That was around 1821 or so.

Wilhelm Schickard builds the first mechanical calculator in 1623. It can work with six digits, and carries digits across columns. It works, but never makes it beyond the prototype stage.

Anyone who is baffled by mathematics beyond the multiplication tables can imagine with awe the Brobdingnagian mental efforts involved in inventing a clerkproof, 5,500-part machine that ...

Babbage's machines include a mechanical calculator called the "Difference ... shifted to designing the "Analytical Engine," which was first described in 1837. The Analytical Engine comprised ...

The first winner reaches a speed of 42mph ... Mathematician Charles Babbage builds his difference engine (or automatic mechanical calculator) to improve significantly the accuracy of the calculations ...

The story of computers started a long, long time ago. The first mechanical calculator was built by Charles Babbage. He worked together with Ada Lovelace, who was the world's first computer programmer.
