Answer:
36
Step-by-step explanation:
When evaluating an expression, you must take PEMDAS into account. PEMDAS stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
You follow these steps, for example, in this expression we don't have any parenthesis or exponents, leaving us to do multiplication first instead of addition:
12 + 24
Now, all you have to do is add these two together:
36
