If there is more than one multiplication division step in a problem, what order should you do them?

You should follow PEMDAS, meaning what ever is in parenthesis goes first. Then exponents, multiplication, division, adding, and last subtraction.

For example, 3(3x + 1)/2 = [x = 3]

Parentheses: 3 x 3 = 9 + 1 = 10 (only reason why your adding 1 to it, is because you do everything in the parentheses.

Exponents: there is none so skip.

Multiplication: 3 x 10 = 30.

Now keep in mind in this example it would look like this so far (30 / 2 = )

Division: 30 / 2 = 15.

Adding: you skip! [because after following pemdas (in order) there is nothing left in the equation that is left to add]

Subtraction: skip as well, (because following pemdas, there would be nothing left to subtract).

Thus, your final answer in this example would be 15!
