This was on my 5th grader's homework:
what is the least number you can make using all of the digits from 0 through 9 exactly once?
My answer was 1,023,456,789. The teacher says it's 0,123,456,789.
I think that if the zero is the first digit, it's not actually part of the number.
???

I agree with you.

i don't get it...

And I concur with Ms Sue.
In our standard way of writing numbers, the lead digit cannot be a zero. 
Thank you! Glad to know you agree with me.
Does make me wonder, though, if other incorrect info is being given in class.
