Question: Is counting a natural ability that everyone has? im sure our cavemen ancestors knew how to count how many coconuts were in a tree and maybe after a while they became more advanced and created symbols to represent the numbers. Can animals count? would they be able to do basic math? like subtracting how many coconuts they have eaten?
Quote: Because zero is a relatively new number to humans, we normally use zero purely as a cardinal number, so we define quantities with it, but don't count with it.
Comment:I never thought much about the number zero because we do only use that number to define a quantity, to show that there is nothing there.
