Answer 2

Answer:

The abacus, also called a counting frame, is a calculating tool that has been in use since ancient times and is still in use today. It was used in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the written Arabic numeral system. The exact origin of the abacus is still unknown.

The abacus was invented in China, around 1300 BC. It was popularized during the Ming dynasty (1368 AD to 1644 AD), and has been a very popular calculating device ever since.
