Simplify \(6\times 7\) to \(42\).
\[3\times \frac{13+42}{11\times 3}-(12-4\times 2)\]
Simplify \(13+42\) to \(55\).
\[3\times \frac{55}{11\times 3}-(12-4\times 2)\]
Simplify \(11\times 3\) to \(33\).
\[3\times \frac{55}{33}-(12-4\times 2)\]
Simplify \(4\times 2\) to \(8\).
\[3\times \frac{55}{33}-(12-8)\]
Simplify \(12-8\) to \(4\).
\[3\times \frac{55}{33}-4\]
Use this rule: \(a \times \frac{b}{c}=\frac{ab}{c}\).
\[\frac{3\times 55}{33}-4\]
Simplify \(3\times 55\) to \(165\).
\[\frac{165}{33}-4\]
Simplify \(\frac{165}{33}\) to \(5\).
\[5-4\]
