They are the same because the first one you do 2 x 3 which equals 6 and then you do 2 x 6 which equals to 12. Then you do 12 x 6 which equal to 72. Then for the second one you do parentheses first so that 2x6 which equals 12 and then you x 6 so now it would be 12 x 6 equal to 72. SO YOUR ANSWER IS THEY ARE THE SAME
