Tricky Math Puzzles : World's Prettiest and Trickiest Math Puzzles

This book comprises certainly the prettiest and trickiest math puzzles you've ever seen. You need not be Einstein to solve the puzzles, and there are no complex calculations required to solve them, but they will certainly help you get smarter. For example: 29=29, 39=39, 49=49 but 66 is not 66. Also: 11+12=23, but 45+32=95. You only need to add, subtract, multiply, divide, and use square root, though sometimes there is no calculation required at all, but rather some other approach. All puzzles have different graphics, each one done in a pretty way. The puzzles are brain teasers, head crackers and mind blowers. None of the puzzles involve complex calculations. The answers are so simple, so within reach, and yet so hard to get to.
