    why did you take 9 - 12 first? Instead of 20 + 9. Why is there no explanation on the order? Why did you work left to right instead of right to left. I can go no further and i guess, obviously take a prior course. This is why I haven't completed an algebra course since 7th grade. It would have been very easy for the instructor to add remember to work left to right, yet like all courses, no questions, no answers. Thank you, Ray

    PEMDAS, parentheses, exponents, multiply, divide, add , subtract. The guy in the video did the step wrong, he subtracted first instead of adding, PEMDAS... AS... add, then subtract.... Error? Or is the information on the internet wrong...you decide, ive made my decision, and moving forward...although 20 + 9 - 12, left to right is the same answer, 17, it sure doesn't help to answer a question backwards
