you have to solve what's in the parenthesis before the exponent. 5 and 2 are two numbers in one variable

6*9/9=6*1=6 ? If there only exist M and D in operation, there is no order for M and D. Is that true?

in the example of 6*9/9 you said that there is no order for multiplication and division... but... how about this one: 6/2*3=?

If I choose to do first the multiplication or division, as a result we'll have a different number.

Overall, this was a great lesson. However, it was a bit confusing when Professor Pyo went through PEMDAS. She continued to explain that M-D and A-S were the same. I felt that a little more explanation on what she meant by “the same” would have been helpful. The amount of examples helped to learn the concept of order of operations.
