Using the numbers [3, 15, 22, 66], create an equation that equals 37. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags, like 10 + 22 - 3 * (15/3) = 20 + 3 * 2 = 26 + 3 = 29. Then return both your final equation and answer in <answer> </answer> tags, such as <answer> (10 + 22 - 3 * (15/3)) = 37 </answer>.<|im_end|>
