Miss. Hipkins was given the math problem: (3+7)-34*3^2/2. She started by doing 34*3. Was she correct by starting with multiplication? Why or why not? If not what should she have started with.
She was wrong, she should have started with (3+7) because parenthesis is the first step of PEMDAS. Not multiplication.
She is not correct. Miss. Hipkins did 6*3 when she should have done 6*6*6. Her answer should have been 216.
