Solution - Long multiplication
90
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | tens | ones |
| 1 | 8 | |
| × | 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 18, from right to left.
Multiply the ones digit (5) of the multiplicator by the number in the ones place value:
5×8=40
Write 0 in the ones place.
Because the result is greater than 9, carry the 4 to the tens place.
| Place value | tens | ones |
| 4 | ||
| 1 | 8 | |
| × | 5 | |
| 0 |
Multiply the ones digit (5) of the multiplicator by the number in the tens place value and add the carried number (4):
5×1+4=9
Write 9 in the tens place.
| Place value | tens | ones |
| 4 | ||
| 1 | 8 | |
| × | 5 | |
| 9 | 0 |
The solution is: 90
