Just click the add# circles and type in the number. Pretty simple. Only has 9 scripts and 8 sprites.
The division quotient will sometimes equal Infinity or NaN (Not a Number) because, for example, how many times does 0 fit into 0? You might say 0 times, but now tell me what's 999 times 0. 0, right? So there are infinite combinations and that's why it will say NaN or Infinity.
