  • start with 0
  • then add 1 = 1
  • add another 1 = 2
  • add another 1 = 3
  • add another 1 = 4
  • add another 1 = 5

but you can also multiply, and anything multiplied by 0 is 0:

  • start with 0
  • multiply by 2 = 0
  • multiply by 2 = 0
  • multiply by 2 = 0
  • multiply by 2 = 0
  • multiply by 2 = 0
