Yes, zero is a number.
Yes, zero is a number.
Edit: Zero is actually not classified as a number - it is a separator. It stands for nothing. Take as an example the number One hundred and nine (109). Without the zero to separate the 100 from the 9, it would look the same as the number 19 !
Edit 2: Zero IS a number and not just a separator. The set of numbers (integers or rationals or reals or complex) includes, AS A MEMBER, an additive identity such that for any member x in the set, x + i = i + x. This additive identity is denoted by the number 0. So it is very much a number.
