Answer:
Because for the first problem you would have to simplify 8 divided by 2 into 4 in which 12 - 4 = 8 then you would have to simplify 12 - 4 to 8 which 8 = 8
Because for the second problem you would have to simplify 12 - 8 to 4 which 4 divided by 2 = 2 then you would have to simplify 4 divided by 2 to 2 which 2 = 2
There are parentheses which if there weren't you would get a different answer
