How many numbers with exactly four digits can you make with the digits 012345678 and 9 the first digit may not be 0?

well you would probably have to mutiply 9 times ten times ten times ten, because you have four spaces for any number up to nine and zero can't be used in the first digit. My answer would have to be 9000, although I'm only in eighth grade. Anyone who has time to write out every possibility, though, has no life.
