Babylonian zero? Greek zero and mayna zero?

Question

what is babylonian zero, greek zero and mayna zero?

Answer 1

You may go to http://en.wikipedia.org/wiki/ as a source for yours.

Answer 2

They were equivalent ways of representing the originally Indian symbol for zero.  My keyboard can't cope with them, as it happens.  If I remember correctly, the Babylonian one was actually a space.

Answer 3

Answer 4

Babyonian did not have a real number zero (the integer before 1) but used a space as a placeholder when needed.

The greek philosophers denied the existence of zero, saying 'How can nothing be something?'

The mayans used a symbol, see http://en.wikipedia.org/wiki/Image:MAYA-... as a symbol for zero in dates.
