One day, you enter your math classroom. On the board, there are the words POP QUIZ.

Dang it! Was it about fractions? you knew you were bad with fractions.

You look down.

$\begin{array}{|cc|} \hline \text{You can only use your brain, and paper. } \\ \text{The number of digits in this box that are not 1 is} & \text{_______} \\ \text{The number of digits in this box that are not 2 is} & \text{_______} \\ \text{The number of digits in this box that are not 3 is} & \text{_______} \\ \text{The number of digits in this box that are not 4 is} & \text{_______} \\ \text{The number of digits in this box that are not 5 is} & \text{_______} \\ \text{The number of digits in this box that are not 6 is} & \text{_______} \\ \text{The number of digits in this box that are not 7 is} & \text{_______} \\ \text{The number of digits in this box that are not 8 is} & \text{_______} \\ \text{The number of digits in this box that are not 9 is} & \text{_______} \\ \hline \end{array}$
