"Each lily pad holds a math question."
"Hop to a pad and answer it."

Bennie chuckles. "Remember, every division fact hides a times fact."

Check each fact, and multiply tens with care.
| Sentence | True or false? |
|---|---|
| 9 × 8 = 72 | ? |
| 72 ÷ 9 = 8 | ? |
| 6 × 30 = 160 | ? |
| 3 × 4 = 4 × 3 | ? |
WHY THIS EXERCISE6 × 30 is 18 tens, so it is 180, not 160.
