Evaluate the expression using order of operations.

$\frac{\left ( -6 \right )\left ( 7-6 \right )+\left ( -6 \right )\left ( 6 \right )}{\left ( -6 \right )\left ( 4-1 \right )}$

Solution:-

$\frac{[(-6)(1)-36]}{(-6)(3)}$

= $\frac{(-6-36)}{(-18)}$

= $\frac{-42}{-18}$

= $\frac{42}{18}$

= $\frac{21}{9}$

= $\frac{7}{3}$
