Answer 1

a)

$\frac{\begin{matrix}\space\space&\textbf{1}&1&1&1&\space\space\\ \space\space&\textbf{4}&8&5&6&7\\ \space\space&\textbf{0}&3&8&9&6\\ +&\textbf{0}&0&3&2&5\end{matrix}}{\begin{matrix}\space\space&\textbf{5}&2&7&8&8\end{matrix}}\\\\=52788$

b)

$\frac{\begin{matrix}\space\space&\textbf{4}&13&15&16&12\\ \space\space&\textbf{\linethrough{5}}&\linethrough{14}&\linethrough{16}&\linethrough{17}&\linethrough{2}\\ -&\textbf{0}&8&7&9&8\end{matrix}}{\begin{matrix}\space\space&\textbf{4}&5&8&7&4\end{matrix}}\\\\=45874$

c)

$\frac{\begin{matrix}\space\space&\space\space&4&5&8&4&3\\ \space\space&\times \:&\space\space&\space\space&\space\space&9&6\end{matrix}}{\begin{matrix}0&2&7&5&0&5&8\\ 4&1&2&5&8&7&0\end{matrix}}\\\\\frac{\begin{matrix}\space\space&\textbf{\space\space}&1&1&\space\space&1&\space\space&\space\space\\ \space\space&\textbf{0}&2&7&5&0&5&8\\ +&\textbf{4}&1&2&5&8&7&0\end{matrix}}{\begin{matrix}\space\space&\textbf{4}&4&0&0&9&2&8\end{matrix}}\\\\=4400928$

d)

$multiplique\\2976\times \:58\times \:34\\\\=5868672 < "calculadora"$

e)

$\frac{6278}{73}\\\\=86$
