Decoding Place ValueDate: 09/14/2003 at 18:02:20 From: Samantha Subject: base 10 What does it mean to be in base 10? What does the 1 represent? What does the 0 represent? I think I understand the 1 to represent one 10, but I'm a little confused about the 0. Does it mean that there are no units left over from base 10?
