Worked Example
Calculate 24 * 16 using partial products:
1
Break factors into place values
(20 + 4) * (10 + 6)
Decompose factors into tens and ones.
2
Multiply partial products
20*10=200, 20*6=120, 4*10=40, 4*6=24
Calculate the 4 rectangular areas.
3
Sum the partial products
200 + 120 + 40 + 24 = 384
Total product is 384.
✓Verification Check
Verify by division: 384 / 16.
384 / 16 = 24
•
24 = 24
⚠️ Common Pitfalls & Misconceptions
Forgetting place-value zeros when multiplying tens
✗ Multiplying 20 * 10 and writing 20 instead of 200✓ Multiply non-zero digits and append total trailing zeros
Tens times tens equals hundreds.
