#### Explanation:

When evaluating expressions involving $\textcolor{b l u e}{\text{mixed operations}}$ we must do so in a particular order.

Follow the order as set out in the acronym PEMDAS.

$\left(6 + 7\right) \times 2 - 1$

$= 13 \times 2 - 1 \leftarrow \textcolor{red}{\text{ bracket first}}$

$= 26 - 1 \leftarrow \textcolor{red}{\text{ next is multiplication}}$

$= 25 \leftarrow \textcolor{red}{\text{ finally subtraction}}$
