    is the original question\[{30\over5(3-1)}-4\]? or is it just as you printed it?

    it could be\[{30\over5}(3-1)-4\]if the notation is unclear

    well, if the division symbol is as you have it, then I say no mistakes are made and I cannot read your teacher's mind. Anybody see a problem with my observation?

    if there is a mistake it would be that Line 1 30 ÷ 5(3 - 1) - 4 Line 2 30 ÷ 5(2) - 4 should lead to 60÷5-4 but that seems extraneous... I'm gonna say no mistakes.

    Its line 3.. I have to use PEMDAS to do this problem..

    It would be line 3 because she or he forgot to divide 30 by 5 it should look like this. 30/5(3-2)-4 30/5(2)-4 5(2)-4 6

    30/5(3-2)-4 30/5(2)-4 does not lead to 5(2)-4 no matter how you slice it, so that makes no sense...

    30/5(2)-4 = 6(2)-4 if your working strictly from lt to rt

    you misprinted the problem as you just noticed 30/5(3-1)-4 30/5(2)-4 does not lead to 5(2)-4 no matter how you slice it, so that makes no sense...

    cwrw's interpretation is possible, but it means the original question is the second option I posted above. this is why the division symbol "÷" is ridiculously vague

    It would be line 3 because she did not do it right.. she did 5(2) before she did 30/5 on line two witch makes line three incorrect and if she got line three incorrect everything below would be incorrect to. it should look like this. 30/5(3-1)-4 30/5(2)-4 6(2)-4 12-4 8

    should be written as\[\frac{30}{5}(3-1)-4\]to get this answer...
