What Math Riddles are?
Math riddles are a kind of puzzle or question that seems simple and easy to answer, but it requires logical thinking, reasoning, and a high IQ. Math questions are not always solved by number calculations; instead, it also depends on how you understand the problem.
Example:
Questions:
There is a number 12. If you subtract 30 from it, the remaining value is still a positive value; you may be calculating both values as 12-30=-18. But as per the question, the answer value will be positive, as the riddle answer is hidden cleverly and the answer might be multiple.
Answer:
- In a clock, 12 represents the time 12:00, and 30 represents 30 minutes. So if you remove 30 minutes from 12:00, the answer is still positive, which is 11:30.
- There are 12 months in a year. If you subtract any 30-day month, the value is still positive, which leaves 11 months.
