Megoldás - Long multiplication
Lépésről lépésre magyarázat
1. Rewrite the numbers from top to bottom aligned to the right
| Helyiérték | ezresek | százasok | tízesek | egyesek | . | tizedek |
| 0 | , | 2 | ||||
| × | 1 | 0 | 0 | 0 | ||
Ignore the decimal points and multiply as if these are whole numbers (as if each most right digit is the ones digit):
In this case we removed 1 decimal place(s). So once calculated, the result will be reduced by the factor of 10.
| Helyiérték | ezresek | százasok | tízesek | egyesek |
| 2 | ||||
| × | 1 | 0 | 0 | 0 |
2. Multiply the numbers using long multiplication method
Because the százasok digit of the multiplicator equals 0, skip to the next digit.
Proceed by multiplying the ezresek digit (1) of the multiplier (1 000) by each digit of the multiplicand (2), from right to left.
Because digit (1) is in ezresek place, we shift partial result by 3 place(s) by placing 3 zero(s).
| Helyiérték | ezresek | százasok | tízesek | egyesek |
| 2 | ||||
| × | 1 | 0 | 0 | 0 |
| 0 | 0 | 0 |
Multiply the ezresek digit (1) of the multiplicator by the number in the egyesek place value:
1×2=2
Write 2 in the ezresek place.
| Helyiérték | ezresek | százasok | tízesek | egyesek |
| 2 | ||||
| × | 1 | 0 | 0 | 0 |
| 2 | 0 | 0 | 0 |
2 000 is the first partial product.
3. Add the partial products
2000=2000 long addition steps can be seen here
| Helyiérték | ezresek | százasok | tízesek | egyesek |
| 2 | ||||
| × | 1 | 0 | 0 | 0 |
| + | 2 | 0 | 0 | 0 |
| 2 | 0 | 0 | 0 |
Because we have 1 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 1 time(s) to the left (reducing the result by the factor of 10) to get the final result:
The solution is: 200
