$1427$

#### Explanation:

When evaluating expressions with $\textcolor{b l u e}{\text{mixed operations}}$ there is an order which must be followed.

Follow the order as set out in the acronym PEMDAS ( Parenthesis , Exponents, Multiplication, Division, Addition, Subtraction )

$\Rightarrow {3}^{6} - {9}^{2} + 5 + 18 \times 43$

$= 729 - 81 + 5 + 18 \times 43 \leftarrow \textcolor{red}{\text{exponents}}$

$= 729 - 81 + 5 + 774 \leftarrow \textcolor{red}{\text{multiplication}}$

Addition and subtraction is now performed from left to right.

$\Rightarrow 729 - 81 + 5 + 774 = 1427 \leftarrow \textcolor{red}{\text{addition/subtraction}}$
