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.

???

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.
