  1. 30 · 24 + 6 = 30.
  2. 24 · The steps add 6, so 18 + 6 = 24.
  3. 24 · Each jump adds 6. 18 plus 6 is 24.
  4. True · 75 plus 25 is 100, so the pattern goes 25, 50, 75, 100.
  5. 28 · 21 + 7 = 28.
  6. 18 · Between 12 and 24, the missing jump of 6 is 18.
  7. 42 · 42 = 6 x 7. The rest leave remainders when split into 6s.
  8. True · Lena is right: 9 lots of 6 is exactly 54.
  9. He added 8 instead of 7 one time · 14 plus 7 should be 21, but Ben got 22, so he added 8 that time.
  10. 72 · 6 x 12 = 72, the top of the 6s to 72.
