Using the numbers [5, 6, 90, 10], create an equation that equals 52. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags. Additionally, provide examples of correct and incorrect attempts, as well as an explanation of why they are correct or incorrect. And return the final equation and answer in <answer> </answer> tags, for example <answer> (12 - 5) * 4 = 32 </answer>. Your final output should include your equation, a check that the target number is reached, a detailed explanation of your logic, and at least two examples of attempts with explanations.<|im_end|>
