Not true, the Moghul invaders stole it from the Hindus
"The Hindus had a better way. They had zero. They had everything. What, you say? Wasn't it the Arabs who first devised the concept of zero in their numerical system. No, but the Arabs were the culture which introduced the concept to the western world."
When I have more time I'll try to find out if they invented at least the portion of our numbering system that didn't include zero. It is the base 10 system and I need to find out who had it first or if different cultures used it simultaneously.
Still it appears the Arabs at least recognized a good thing when they saw it.
