When did Charles Babbage invent the abacus?

Answer 1

While Charles Babbage did invent a calculator as well as what is considered the first programmable computer, he did not invent the abacus. This basic counting tool was invented in China around 3000 B.C. Babbage most certainly would have known of the abacus, indeed he likely would have used one himself, but it is not a tool of his original design.

Answer 2

No. An abacus, or counting frame, is a simple machine that consists of beads threaded over rods within a rectangular frame, and is used for performing simple math calculations. The earliest known use of the abacus dates back to Mesopotamia and Babylon more than 2,500 years BCE, but it has been used in some form by many early cultures, including the Chinese, Japanese, Korean, Greek, Egyptian, Roman, and Persian (Iranian), to name a few.

Charles Babbage invented more complex automated calculating devices known as the Difference Engine and the Analytical Engine.

Answer 3

No. Charles Babbage lived in nineteenth century England.

The abacus was widely used long before the birth of Christ.

What Babbage did invent was the first automatic, stored program computer with conditional branching. It was purely mechanical in operation. It was a brilliant idea which was a hundred years ahead of the technology that was needed to make it really workable.
