To evaluate any expression involving more than one operation, follow the below order of operations:

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.

Step 2. Simplify expressions on numerator and denominator

In order to evaluate the given expression, first simplify the numerator and denominator expression and then divide the resulting numbers as shown below

$\begin{matrix} \frac{18 + 12}{7 - 2} = \frac{30}{7 - 2} \\ = \frac{30}{5} \end{matrix}$

Step 3. Divide the numbers
