30. I missed the multiplication but remembered the order of operation.

Two tricks to this puzzle:

1. You have to remember to do the multiplication before you do the addition.

2. You have to notice that the man in all the pictures except the last one has no shoes and no wrist straps. But in the last picture, he is wearing two shoes and two wrist straps, so you have to add those values in before you do the math. So 5 (man) + 10 (shoes he's wearing) + 4 (wriststraps he's wearing) = 19.

So the final problem is 5 + (19 x 2) = 5 + 38 = 43.

I see these things all the time on Facebook and they drive me nuts. There can't be a "correct" answer derived purely from the information given because none of the 3 symbols shown on the unsolved line appear in any of the previous two lines. You can assume that [one shoe] is half the value of [two shoes]—and there is a logic to that—but without those symbols appearing in lines that contain an answer, all you can ever do is make a guess. For all we know, [two shoes] = 10 and [one shoe] = 68,002. They're different symbols.

Kind of like how "2" isn't half of "22".
