What is in this set

The numbers in this set run from 1 to 996.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 91% of the problems: the digits were counted; the power is how many places the point moves, which is one fewer.
Answers are a whole number.

Drawing 240 problems from this page produced 232 different ones, 97% — so a sheet of 20 is a new sheet almost every time.
