$$A= \frac{ 7 }{ 6 } +- \frac{ 5 }{ 2 } \times \frac{ 4 }{ 3 }$$
$A = -\frac{13}{6} = -2\frac{1}{6} \approx -2.166666667$
$$A=\frac{7}{6}+\frac{-5\times 4}{2\times 3}$$
$$A=\frac{7}{6}+\frac{-20}{6}$$
$$A=\frac{7}{6}-\frac{10}{3}$$
$$A=\frac{7}{6}-\frac{20}{6}$$
$$A=\frac{7-20}{6}$$
$$A=-\frac{13}{6}$$
