Smallest and largest numbers
A set of digits is given, and the student makes the largest or the smallest number that uses every one of them.
Zeros are where it gets tricky: a number can't start with 0, so the smallest number from 8, 6, 2, 0 and 0 is 20,068. The step-by-step working shows the digits being put in order.
