Using the numbers [2, 10, 25, 20], create an equation that equals 89. 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> 2 * 25 + 10 = 60, 60 * 2 + 20 = 140, (140 - 20) / 2 = 60, (60 + 2) = 62, (62 * 2) + 10 = 134, ((134 - 25) * 2) + (10 + 20) = 89 </answer>.<|im_end|>
