\(\textcolor{#808080}{\text{Треугольники — 3 строки по}}\) \(\textcolor{#808080}{\text{4, 4 столбца по}}\) \(\textcolor{#808080}{\text{3:}}\) \[\textcolor{#e03131}{\boldsymbol{4 \cdot 3 = 12}} \qquad \textcolor{#e03131}{\boldsymbol{3 \cdot 4 = 12}}\] \(\textcolor{#808080}{\text{Ромбы — 2 строки по}}\) \(\textcolor{#808080}{\text{5, 5 столбцов по}}\) \(\textcolor{#808080}{\text{2:}}\) \[\textcolor{#e03131}{\boldsymbol{5 \cdot 2 = 10}} \qquad \textcolor{#e03131}{\boldsymbol{2 \cdot 5 = 10}}\]
\({9 \cdot 2 = 2 \cdot \textcolor{#e03131}{\mathbf{9}}} \qquad\allowbreak {15 \cdot 3 = \textcolor{#e03131}{\mathbf{3}} \cdot 15}\)
\({25 \cdot 2 = \textcolor{#e03131}{\mathbf{2}} \cdot 25} \qquad\allowbreak {14 \cdot 4 = 4 \cdot \textcolor{#e03131}{\mathbf{14}}}\)
2) \({5 + 8 = 9 + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em}} \qquad\allowbreak {13 - \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{5}}\kern0.035em} = 16 - 8}\)
\({\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{2}}\kern0.035em} + 9 = 3 + 8} \qquad\allowbreak {11 - 5 = \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{1}}\kern0.035em}\hspace{-0.04em}\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em} - 7}\)
\(13 - 6 = \textcolor{#e03131}{\mathbf{7}}\text{ (з.)}\)
Ответ: на \(\textcolor{#e03131}{\mathbf{7}}\) замков больше.
