Simplify \(-7\times (-6)\) to \(42\).
\[\begin{aligned}&42+17\\&-4\times \frac{-3}{12}\end{aligned}\]
Use this rule: \(a \times \frac{b}{c}=\frac{ab}{c}\).
\[\begin{aligned}&42+17\\&-\frac{4\times -3}{12}\end{aligned}\]
Simplify \(4\times -3\) to \(-12\).
\[\begin{aligned}&42+17\\&-\frac{-12}{12}\end{aligned}\]
Move the negative sign to the left.
\[\begin{aligned}&42+17\\&-(-1)\end{aligned}\]
Remove parentheses.
\[\begin{aligned}&42+17\\&+1\end{aligned}\]
