Перемножить числа:
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| x | ||||||
| \(\displaystyle 7\) | \(\displaystyle 1\) | \(\displaystyle 0\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle +\) | ||||||
1. Умножаем единицы числа \(\displaystyle 71{\underline 0} \) (это число \(\displaystyle 0 \)) на число \(\displaystyle 461{\small,}\) получаем:
\(\displaystyle 0 \cdot 461=0{\small.}\)
Записываем результат в первую строку:
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| x | ||||||
| \(\displaystyle 7\) | \(\displaystyle 1\) | \(\displaystyle \bf0\) | ||||
| \(\displaystyle \bf0\) | \(\displaystyle \bf0\) | \(\displaystyle \bf0\) | ||||
\(\displaystyle +\)
| ||||||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | |||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | |
2. Умножаем десятки числа \(\displaystyle 7{\underline 1}0 \) (это число \(\displaystyle 1 \)) на число \(\displaystyle 461{\small,}\) получаем:
\(\displaystyle 1 \cdot 461=461{\small.} \)
Записываем результат во вторую строку:
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| x | ||||||
| \(\displaystyle 7\) | \(\displaystyle \bf1\) | \(\displaystyle 0\) | ||||
| \(\displaystyle 0\) | \(\displaystyle 0\) | \(\displaystyle 0\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle \bf4\) | \(\displaystyle \bf6\) | \(\displaystyle \bf1\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | |||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | |
3. Умножаем сотни числа \(\displaystyle {\underline 7}10 \) (это число \(\displaystyle 7 \)) на число \(\displaystyle 461{\small,}\) получаем:
\(\displaystyle 7 \cdot 461=3227{\small.} \)
Записываем результат в третью строку:
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| x | ||||||
| \(\displaystyle \bf7\) | \(\displaystyle 1\) | \(\displaystyle 0\) | ||||
| \(\displaystyle 0\) | \(\displaystyle 0\) | \(\displaystyle 0\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle \bf3\) | \(\displaystyle \bf2\) | \(\displaystyle \bf2\) | \(\displaystyle \bf7\) | |||
| \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | \(\displaystyle {\small?}\) | |
4. Складываем числа:
| \(\displaystyle 0\) | \(\displaystyle 0\) | \(\displaystyle 0\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle 3\) | \(\displaystyle 2\) | \(\displaystyle 2\) | \(\displaystyle 7\) | |||
| \(\displaystyle 3\) | \(\displaystyle 2\) | \(\displaystyle 7\) | \(\displaystyle 3\) | \(\displaystyle 1\) | \(\displaystyle 0\) | |
В итоге получаем:
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| x | ||||||
| \(\displaystyle 7\) | \(\displaystyle 1\) | \(\displaystyle 0\) | ||||
| \(\displaystyle 0\) | \(\displaystyle 0\) | \(\displaystyle 0\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle 4\) | \(\displaystyle 6\) | \(\displaystyle 1\) | ||||
| \(\displaystyle +\) | ||||||
| \(\displaystyle 3\) | \(\displaystyle 2\) | \(\displaystyle 2\) | \(\displaystyle 7\) | |||
| \(\displaystyle 3\) | \(\displaystyle 2\) | \(\displaystyle 7\) | \(\displaystyle 3\) | \(\displaystyle 1\) | \(\displaystyle 0\) | |
