Solution - Long multiplication
448
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | hundreds | tens | ones |
| 6 | 4 | ||
| × | 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 64, from right to left.
Multiply the ones digit (7) of the multiplicator by the number in the ones place value:
7×4=28
Write 8 in the ones place.
Because the result is greater than 9, carry the 2 to the tens place.
| Place value | hundreds | tens | ones |
| 2 | |||
| 6 | 4 | ||
| × | 7 | ||
| 8 |
Multiply the ones digit (7) of the multiplicator by the number in the tens place value and add the carried number (2):
7×6+2=44
Write 4 in the tens place.
Because the result is greater than 9, carry the 4 to the hundreds place.
| Place value | hundreds | tens | ones |
| 4 | 2 | ||
| 6 | 4 | ||
| × | 7 | ||
| 4 | 4 | 8 |
The solution is: 448
