(6 * 3 * 3) + 398 = 452
900 − (4 * 3 * 2) = 876
(9 * 0 * 8 * 7) + (1 * 9 * 2 * 2 * 2) = 72
(7 * 2 * 4) − (6 * 2 * 4) = 8
Ответы в порядке увеличения: 8, 72, 452, 876.
Вычисления:
(6 * 3 * 3) + 398 = 54 + 398 = 452
$\begin{array}{r}\begin{array}{r}+\end{array}\underline{\begin{array}{r}54\\ 398\end{array}}\\ \begin{array}{r}452\end{array}\end{array}$
900 − (4 * 3 * 2) = 900 − 24 = 876
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}900\\ 24\end{array}}\\ \begin{array}{r}876\end{array}\end{array}$
(9 * 0 * 8 * 7) + (1 * 9 * 2 * 2 * 2) = 0 + 72 = 72
(7 * 2 * 4) − (6 * 2 * 4) = 56 − 48 = 8
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}56\\ 48\end{array}}\\ \begin{array}{r}8\end{array}\end{array}$
