Solution - Long multiplication
65
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | tens | ones |
| 1 | 3 | |
| × | 5 | |
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (5) of the multiplier 5 by each digit of the multiplicand 13, from right to left.
Multiply the ones digit (5) of the multiplicator by the number in the ones place value:
5×3=15
Write 5 in the ones place.
Because the result is greater than 9, carry the 1 to the tens place.
| Place value | tens | ones |
| 1 | ||
| 1 | 3 | |
| × | 5 | |
| 5 |
Multiply the ones digit (5) of the multiplicator by the number in the tens place value and add the carried number (1):
5×1+1=6
Write 6 in the tens place.
| Place value | tens | ones |
| 1 | ||
| 1 | 3 | |
| × | 5 | |
| 6 | 5 |
The solution is: 65
