• First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
• Evaluate the exponents.
• Perform Multiplication and division from left to right.
• Perform addition and subtraction from left to right

- Simplify expression inside grouping symbol 

To evaluate the value of the given expression, first simplify the expression inside the parenthesis and then multiply it with 3 as shown below

$\begin{array}{c}3\left(8+3\right)-4=3\left(11\right)-4\\ =33-4\end{array}$
