How it works
Multiply each digit, ones first. Carry the extra.
A zero starts the tens row. Add the rows.
Estimate first to check.
Worked examples
Two digits
- ? = 151 × 54
- 151 × 4 = 604.
- 151 × 50 = 7550, then 604 + 7550 = 8154.
- So the answer is 8154.
A zero in the middle
- 206 × 74 = ?
- 206 × 4 = 824.
- 206 × 70 = 14420, and 824 + 14420 = 15244.
- So the answer is 15244.
A big number
- 9145 × 56 = ?
- 9145 × 6 = 54870.
- 9145 × 50 = 457250, and 54870 + 457250 = 512120.
- So the answer is 512120.
