  1. 7 · 15 minus 8 = 7. It is the flip side of 7 + 8 = 15.
  2. 100 · 6 tens + 4 tens = 10 tens = 100.
  3. 15 · 9 + 6 = 15, recalled fast.
  4. 15 · 7 + 8 = 15. Say it fast, like you already know it by heart.
  5. True · Leo is right: 5 + 5 = 10, so 35 + 5 = 40.
  6. 50 · 7 tens take away 2 tens leaves 5 tens.
  7. 30 · 5 + 5 = 10, so 25 + 5 bridges to 30.
  8. 7 · 16 minus 9 = 7. Think: 9 + 7 = 16, so taking away 9 leaves 7.
  9. 50 · 45 + 5 is like 40 + 5 + 5. Since 5 + 5 = 10, the total is 50.
  10. True · Dan is right: 6 + 4 = 10, so 46 + 4 = 50.
