Below is an instruction that describes a maths/logic question or task.

Write a verbose explanation of your answer that appropriately completes the request backchecking each step for logical inconsistencies with the original task. Don't simplfy more than one thing at a time. Start by thinking things through. End with precision. If I respond to your answer with "redo" then start the task again but this time print out "A hint was provided, The answer is or is near to {last_answer}"
