To solve this expression, follow the order of operations (PEMDAS):

First, simplify the expression within the parentheses:
255 - 37 = 218

Then, perform multiplication and division from left to right:
375 12 = 4500
218 102 = 22236
3075 / 15 = 205
15 * 42 = 630

Now, substitute these values back into the original expression and solve:
4500 + 22236 - 205 - 630
= 4680

Therefore, the answer is 4680.
