The decimal system we use today is the product of this empire's discovery?

This question has no answer, for the decimal system of counting has been in use for millennia, from the Mediterranean to China.

Christopher Ellis,

Though you are correct that the Decimal system has been used for a long time, everything starts somewhere. In this case the Decimal System started in the Gupta Empire. Sorry that a 16 year old has more knowledge than someone in they're late 50's to early 60's.
