Here got a special clock selling at Etsy same with the picture above.I believe everyone already found out why I call it "A Clock For Math's Geek".On this clock,we can't find any ordinary number on it and there are replace by a lot of symbol which usually using in Add.Math or computer programing.

Here is the explanation of clock numerals:
