__ The Number Zero  __ The number zero was one of the last numbers to gain universal acceptance by mathematicians. The number zero was first recognized in a numeral system sometime in the 9th century A.D. and most likely in India. The Romans had managed to recognize // nothing //in their numeral system a few centuries earlier, but it was denoted by the word // nulla // as opposed to a symbol. Cultures before this had also accepted an absence of numbers, but none had officially recognized zero as itself. The establishment of zero opened the door to other mathematical discoveries: negative numbers, irrational numbers, decimals, etc. To this day, a debate continues on the true significance of the number zero.
