well i didnt know about the origin before.
but these symbols are widely used in ROMAN FONTS and in ENGLISH since thousands of years, so i wrote that, and as i searched about their origon then revealed as follows:

Origins
Buddhist inscriptions from around 300 BC use the symbols which became 1, 4 and 6. One century later, their use of the symbols which became 2, 4, 6, 7 and 9 was recorded. These Brahmi numerals are the ancestors of the Hindu-Arabic glyphs 1 to 9, but they were not used as a positional system with a zero, and there were rather separate numerals for each of the tens (10, 20, 30, etc.).

Positional notation without the use of zero (using an empty space in tabular arrangements, or the word kha "emptiness") is known to have been in use in India from the 6th century. The oldest known authentic document that may be argued to contain the use of zero and decimal notation is the Jaina cosmological text Lokavibhaga, which was completed on August 25, 458.

The first inscription showing the use of zero which is dated and is not disputed by any historian is the inscription at Gwalior dated 933 in the Vikrama calendar (876 CE.)


well thanks for information.
