  1. 11 · 5 plus 6 makes 11. Count on from 5: 6, 7, 8, 9, 10, 11.
  2. 7 + 2 = 9 · Join the two groups to count all the blocks: 7 + 2 = 9.
  3. 9 · Taking away no apples means subtracting 0. 9 - 0 = 9.
  4. 8 · Twelve take away four leaves eight. Count back: 11, 10, 9, 8.
  5. 8 · The two parts make 14: 6 + [ ] = 14. The missing part is 8.
  6. 12 · Remove the 5 added buttons from the final 17: 17 - 5 = 12.
