  1. 37 · Each hop adds 10. The ones digit stays 7, so after 27 comes 37.
  2. 63 · 73 - 10 = 63.
  3. 37 · Only the tens digit moves: 27 to 37.
  4. 24 · Only the tens digit goes up by one: 14 becomes 24. The ones digit, 4, stays the same.
  5. True · Right: 5 tens become 4 tens.
  6. 63 · 73 - 10 = 63.
  7. 77 · 67 + 10 = 77.
  8. 53 · Each hop takes away 10 from the tens digit. After 63 comes 53, and the ones digit stays 3.
  9. 36 · The ones digit should always stay 5. It should have been 35, not 36.
  10. True · Right: 95 + 10 = 105.
