Arabic Numbers

Did you know...
Arabic numbers were NOT invented by Arabs, but were invented by the Hindus of India.
The reason that (0,1,2,3,4,5,6,7,8,9) are known as Arabic numerals despite their Indian heritage is that it was the Arabs who adopted the system from India in the ninth century and introduced it to Europe in the tenth. Europeans therefore wrongly attributed the numerals to the Arabs, even though the Arabs themselves called them "Hindu numerals." Today they are the most common symbolic representation of numbers in the world.
