To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS).

First, we calculate any exponents:
6^2 = 36
3^2 = 9

Next, we perform any multiplication or division from left to right:
3 × 6^2 = 3 × 36 = 108

Finally, we perform any addition or subtraction from left to right:
36 + 108 + 9/(-13)

To simplify the expression further, we divide 9 by -13:
36 + 108 - (9/13)

Now, we can add and subtract:
36 + 108 = 144

Therefore, the final answer is:
144 - (9/13)
