I like math puzzles that are not hard, but gets you thinking in a different way. Life brainwashes all of us to think in certain way and whatever breaks a piece of that brainwash is an eye opener.
- Is 0 an even number?
- Is 1 a prime number?
- Why negative times negative is positive?
- The Monty Hall problem: There are three doors. Behind one of them is a price. You pick one door and then the game-show host opens an empty door. You have the option to change your choice to the remaining door or stick to your original choice. Should you switch or not?
and this:
If I have a 100 g cucumber which is 99% water and I let it dry so that it contains 98% water. How much does the cucumber weigh after drying?
