Using the numbers [82, 15, -73, 9], create an equation that equals 120. To make it interesting, try to use subtraction and think creatively about how the absolute values of the numbers can be manipulated into the target. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags. And return the final equation and answer in <answer> </answer> tags, for example <answer> (1 + 2) * 3 = 9 </answer>.<|im_end|>
