Solution - Long multiplication
7,029
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | thousands | hundreds | tens | ones |
| 7 | 8 | 1 | ||
| × | 9 | |||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (9) of the multiplier 9 by each digit of the multiplicand 781, from right to left.
Multiply the ones digit (9) of the multiplicator by the number in the ones place value:
9×1=9
Write 9 in the ones place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 8 | 1 | ||
| × | 9 | |||
| 9 |
Multiply the ones digit (9) of the multiplicator by the number in the tens place value:
9×8=72
Write 2 in the tens place.
Because the result is greater than 9, carry the 7 to the hundreds place.
| Place value | thousands | hundreds | tens | ones |
| 7 | ||||
| 7 | 8 | 1 | ||
| × | 9 | |||
| 2 | 9 |
Multiply the ones digit (9) of the multiplicator by the number in the hundreds place value and add the carried number (7):
9×7+7=70
Write 0 in the hundreds place.
Because the result is greater than 9, carry the 7 to the thousands place.
| Place value | thousands | hundreds | tens | ones |
| 7 | 7 | |||
| 7 | 8 | 1 | ||
| × | 9 | |||
| 7 | 0 | 2 | 9 |
The solution is: 7,029
