Shortly after he fled, they realized they needed him. This teaches the lesson that you can’t take people for granted because you never know when you may need them for your world to fall into place. Now this book wasn’t so corny until… I got to the part where the numbers were attacked by “roman soldiers” which were roman numerals.
Now zero the hero, despite the fact he had been shunned, still wanted to help his other numbers and live up to his name as the hero. He shows them he can make stuff disappear by multiplying himself with it, and the roman numerals run off. Of course just like real life, everyone wants to be friends with the hero after the fact even if they didn’t believe in him prior. This is just another life lesson that a kid reading this alone wouldn’t exactly get all the way. It would have to be explained. ~~Z.J.
