To make sure I got the question right I used the RUCSAC method which means read, understand, choose, solve, answer, check.
Next I wrote out the numbers 7,8,13,14,3 , followed by 0,1,2,3,4,5,6,7,8,9.And added o to 9 so I did not repeat them, I crossed out the boxes as I went .To make sure I had done them all I did it 3 times. Above are my solutions.
