To get 288 as the correct answer, the problem would have to be written (48/2)*(9+3). Otherwise you cannot divide before solving your denominator. |
You put the denominator in brackets. it was not in brackets originally.
You solve what is in the parentheses first, then work the multiplication and division left to right.
That is what the rules state.
