Answer

102

Work Step by Step

First, complete the operations in the parenthesis: (9-3) and (12+13) And now your equation looks like this: 42 + 12(6)(25)$divide$30. Next, multiply 12 x 6 and now you are left with: 42 + 72(25)$divide$30. Now, multiply 72 x 25 and your equation is now: 42 + 1800 $divide$30. Next, divide 30 into 1800 and you have: 42 + 60 which equals 102.
