Using the numbers [18, 33, 85, 311], create an equation that equals 299. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Start by considering the fundamental operations and possibly introducing parentheses to group operations. Show your work in <think> </think> tags. Verify that you obtain the target number (299). Then, deduce the steps and operations that lead to the final solution. Finally, return the steps and the final equation in a comprehensive form, as shown below in the format of <answer> </answer>.<|im_end|>
