To multiply a multi-digit number by a multi-digit number, multiply
each digit in one number by each digit in the other number.
Step 1: Write the second number under the first number so that the corresponding places are lined up.
Step 2: Multiply the ones digit in the bottom number by each digit in the top number.
| 6 × 8 | = | 48 | | Regroup the 4 to the tens column. |
| 6 × 5 + 4 | = | 34 | | Regroup the 3 to the hundreds column. |
| 6 × 0 + 3 | = | 3 | | |
| 6 × 2 | = | 12 | | |
Step 3: Start a new line, and add a placeholder zero to the ones column. Multiply the tens digit in the bottom number by each digit in the top number.
| 1 × 8 | = | 8 |
| 1 × 5 | = | 5 |
| 1 × 0 | = | 0 |
| 1 × 2 | = | 2 |
Step 4: Then, add to find the product.
