На каждую страницу альбома поместили по 3 открытки. Сколько открыток на шести страницах?
\(3 \cdot 6 = \textcolor{#e03131}{\mathbf{18}}\text{ (о.)}\)
Ответ: \(\textcolor{#e03131}{\mathbf{18}}\) открыток.
Мастер выложил \({\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{2}}\kern0.035em}}\) ряда керамической плиткой, по \({\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{1}}\kern0.035em}\hspace{-0.04em}\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{0}}\kern0.035em}}\) плиток в каждом ряду. Сколько плиток положил мастер?
