Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | tízesek | egyesek |
| 3 | ||
| × | 7 | |
2. Multiply the numbers using long multiplication method
Start by multiplying the egyesek digit (7) of the multiplier 7 by each digit of the multiplicand 3, from right to left.
Multiply the egyesek digit (7) of the multiplicator by the number in the egyesek place value:
7×3=21
Write 1 in the egyesek place.
Because the result is greater than 9, carry the 2 to the tízesek place.
| Helyiérték | tízesek | egyesek |
| 2 | ||
| 3 | ||
| × | 7 | |
| 2 | 1 |
The solution is: 21
