How to roll 100:

  • take 10 sided die, roll once
  • take that number and multiply by 10
  • roll 10 sided die again
  • add that to the number from #2
  • add 1 (otherwise it would be 0-99, not 1-100)
  • Wouldn’t that give you 11-100?

    The Lowest number on a dice is 1, and 1×10 gives you 10.

    The formula would have to be ((d10-1)×10)+d10=x≥90⟹y=y+1

    there’s a 0 on the die
