Answer:
its 28 because you can't subtract 4 from 2 so you crops out the 2 and change it two 12 then subtract 12-4 which equals 8 so now you move on two 5-2 which some you would think is 3 because 5-2 is 3 but what you do is cross out five and change it to 4 finally do 4-2 which equals 2 so 28 is ur answer.
