Pretty Math Puzzles: Blow Your Mind

Pretty Math Puzzles is a book with amazing math puzzles presented in a beautiful way. You only need to add, subtract, multiply, divide, and use square root, though sometimes there is no calculation involved at all, but simply logical thinking. All puzzles have different graphics, each one done in a pretty way. You need not be Einstein to solve the puzzles, 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. The puzzles are brain teasers, head crackers and mind blowers. None of the puzzles involve complex calculations. The answers are very simple, within reach, and yet hard to get to.
