On the History of the Number “Zero"

Muhammad ibn Ahmed al-Khwarizmi 

            I would like to share with you some of my historic knowledge about the nickname of a main character Hector Zeroni. The idea of donating a symbol for nonexistence found by Indians and then this idea was used by Muslim scholars by building the fundamentals of modern mathematics in 10th century. In 976 AD Persian mathematician  Muhammad ibn Ahmed al-Khwarizm, in his "Keys of Science", remarked that if, in a calculation, no number appears in the place of tens, then a little circle should be used "to keep the rows". This circle the Arabs called صفر sifr, "empty". That was the earliest mention of the name Sifr that eventually became zero. 
                Furthermore, the numbers that we use today were borrowed from Arabic numbers and they are too similar, as you can see at the picture. If you cannot observe the similarity, just rotate the Arabic numbers ninety degrees counterclockwise!

There is another interesting detail about “zero”. Arabic writing of zero consists of only a simple dot which mathematically doesn’t have a dimension like other substances like a line, a plane or a cube, even the world we live in it (it is 3-dimensional). Hence zero written as a dot presents actually nonexistence. (204 words)
