Solution - Long multiplication
343
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | hundreds | tens | ones |
| 4 | 9 | ||
| × | 7 | ||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (7) of the multiplier 7 by each digit of the multiplicand 49, from right to left.
Multiply the ones digit (7) of the multiplicator by the number in the ones place value:
7×9=63
Write 3 in the ones place.
Because the result is greater than 9, carry the 6 to the tens place.
| Place value | hundreds | tens | ones |
| 6 | |||
| 4 | 9 | ||
| × | 7 | ||
| 3 |
Multiply the ones digit (7) of the multiplicator by the number in the tens place value and add the carried number (6):
7×4+6=34
Write 4 in the tens place.
Because the result is greater than 9, carry the 3 to the hundreds place.
| Place value | hundreds | tens | ones |
| 3 | 6 | ||
| 4 | 9 | ||
| × | 7 | ||
| 3 | 4 | 3 |
The solution is: 343
