The concept of zero is reality, and was discovered by morons- not invented, or even close to developed. Really, BB- that is your best proffer? Good swing and a miss...
Here from Wikipedia:
“The concept of zero as a number and not merely a symbol or an empty space for separation is attributed to India, where, by the 9th century AD, practical calculations were carried out using zero, which was treated like any other number, even in case of division.” (http://en.wikipedia.org/wiki/0_number)
Notice that it was not Muslim Arabs, which was the point. Mathematics developed over time, with the addition of many new concepts and techniques. The “development” of using zero in mathematical calculations has been wrongly attributed to Islam.
All math is reality. Do you have any point, or anything of value to add?
