The first riddle known was found in a 4500 year old burial mound at Xiaquan in Yunnan province in central China. The riddle is: Mr Riddle puzzle me in and puzzle me out. Riddle me dark from the cave to shout. The question is easy the answer is not. It lives in the future that has yet to arrive. I would if I could I could not and died. Had I have lived I would have not lied. Mr Puzzle riddle me left riddle me right. Puzzle me bright from the fire to light. The answer is easy the question is not. It lies in the past that time has forgot. Do I just jest or do I jest not. I know the truth do I or do I not. What was the question and answer?
A riddle, by its nature, is usually a question in disguise. So if it is given to you as a mathematical question, it is very likely that the answer has nothing to do with mathematics.
