My first answer was 288.
But after thinking back, I realized that was wrong. My teachers taught me an acronym to remember the order of operations:
Please Excuse My Dear Aunt Sally: P E M D A S
Paranthesis, Exponents, Multiply, Divide, Add, Subtract.
So,
48 / 2(9+3) = ???
Step by step.
Paranthesis: 48 / 2(12)
Exponents: None, so problem is still 48 / 2(12)
Multiply: 48 / 24
Divide: 2
There's your answer.
