Big multipliers like 12, 16, 18 and 24 are made of small ones: 12 = 3 × 4, 16 = 4 × 4, 18 = 2 × 9, 24 = 4 × 6. Multiply by the first small number, then by the second. Each step is an easy table fact.
✓ You passed this trick’s test.
Chain the factors — “× 12 = × 3 then × 4; × 16 = × 4 then × 4”
Use it for: Dozens (× 12), hours in days (× 24), boxes of 16 or 18, and any time a big multiplier hides small factors.
Check: 24 × 12 = 24 × 10 + 24 × 2 = 240 + 48 = 288 ✓
