Do you have a typo? ; < this maybe
Yes. hope this is helpful
Its a neutral number cause it has no value since its worth nothing at all, when u add it with something the number ur adding it with will be that number instead of 0, (like for ex 2 + 0 = 2) 0 cant be positive since on a number line its not on the right and it cant be negative since its not on the left, so its neutral in the middle.
