      This is very easy to answer.You go to your teacher and ask for help with your homework.I have already flunked and do not wish to mess up your grades too.

        Here is the solution for you:


        Problem: 3[ 20  - 4 (2 + 1)]


         = 3 [ 20 - 4 × 3]


        = 3 [ 20 -12 ]


        = 3 × 8


        = 24


        Hope this has helped you to some extent. Now share the solution with your friends.


        Note: To solve such kind of problem, you should know the "BODMAS" rule.
