Числа, которые нужно записать в окошках, чтобы равенства были верными: 516, 108, 59, 785.
39 + 516 = 555
296 + 108 = 404
107 − 59 = 48
900 − 785 = 115
Вычисления:
$\begin{array}{r}\begin{array}{r}+\end{array}\underline{\begin{array}{r}39\\ 516\end{array}}\\ \begin{array}{r}555\end{array}\end{array}$
555 − 39 = 516
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}555\\ 39\end{array}}\\ \begin{array}{r}516\end{array}\end{array}$
$\begin{array}{r}\begin{array}{r}+\end{array}\underline{\begin{array}{r}296\\ 108\end{array}}\\ \begin{array}{r}404\end{array}\end{array}$
404 − 296 = 108
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}404\\ 296\end{array}}\\ \begin{array}{r}108\end{array}\end{array}$
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}107\\ 59\end{array}}\\ \begin{array}{r}48\end{array}\end{array}$
107 − 48 = 59
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}107\\ 48\end{array}}\\ \begin{array}{r}59\end{array}\end{array}$
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}900\\ 785\end{array}}\\ \begin{array}{r}115\end{array}\end{array}$
900 − 115 = 785
$\begin{array}{r}\begin{array}{r}-\end{array}\underline{\begin{array}{r}900\\ 115\end{array}}\\ \begin{array}{r}785\end{array}\end{array}$
