Question

1+6(6-1+6(6-1+6(6-6+5))) divided by 7+6

Answer 1

$$\begin{gathered} \mathrm{Dear}\mathrm{Student}, \\ \frac{1+6\left(6-1+6\left(6-1+6\left(6-6+5\right)\right)\right)}{7+6} \\ =\frac{1+6\left(5+6\left(6-1+6\left(5\right)\right)\right)}{7+6} \\ =\frac{1+6\left(5+6\left(5+30\right)\right)}{13}=\frac{1+6\left(5+6\times 35\right)}{13} \\ =\frac{1+6\left(5+210\right)}{13}=\frac{1+6\times 215}{13} \\ =\frac{1291}{13}=99.30 \\ \mathrm{Regards} \end{gathered}$$
