{[9+3) divided by 2] - 2} times [3 times (14 - 5)] =

Step-by-step explanation:

Use PEDMAS

First the inner parenthesis

i) (9+3) & (14-5)

ii) [12 ÷ 2] & [3*9]

iii) {6- 2}

{[(9 + 3) ÷ 2] - 2} * [3*(14 - 5)]={[12 ÷ 2] - 2} * [3*9]

                                            = {6-2}* [27]

                                             = 4 * 27

                                             = 108
