Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
Place value | ten thousands | thousands | hundreds | tens | ones |
3 | 1 | 6 | 8 | ||
× | 8 | ||||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (8) of the multiplier 8 by each digit of the multiplicand 3,168, from right to left.
Multiply the ones digit (8) of the multiplicator by the number in the ones place value:
8×8=64
Write 4 in the ones place.
Because the result is greater than 9, carry the 6 to the tens place.
Place value | ten thousands | thousands | hundreds | tens | ones |
6 | |||||
3 | 1 | 6 | 8 | ||
× | 8 | ||||
4 |
Multiply the ones digit (8) of the multiplicator by the number in the tens place value and add the carried number (6):
8×6+6=54
Write 4 in the tens place.
Because the result is greater than 9, carry the 5 to the hundreds place.
Place value | ten thousands | thousands | hundreds | tens | ones |
5 | 6 | ||||
3 | 1 | 6 | 8 | ||
× | 8 | ||||
4 | 4 |
Multiply the ones digit (8) of the multiplicator by the number in the hundreds place value and add the carried number (5):
8×1+5=13
Write 3 in the hundreds place.
Because the result is greater than 9, carry the 1 to the thousands place.
Place value | ten thousands | thousands | hundreds | tens | ones |
1 | 5 | 6 | |||
3 | 1 | 6 | 8 | ||
× | 8 | ||||
3 | 4 | 4 |
Multiply the ones digit (8) of the multiplicator by the number in the thousands place value and add the carried number (1):
8×3+1=25
Write 5 in the thousands place.
Because the result is greater than 9, carry the 2 to the ten thousands place.
Place value | ten thousands | thousands | hundreds | tens | ones |
2 | 1 | 5 | 6 | ||
3 | 1 | 6 | 8 | ||
× | 8 | ||||
2 | 5 | 3 | 4 | 4 |
The solution is: 25,344
