  • Over 110,000 copies sold of Holger Dambeck's series of math puzzles
  • "Precise, understandable for everyone, and full of humor"—Schwäbisches Tagblatt

Can a cube fit through itself? Why is 2023 a special year? And what do you do with three lies for which there is only one truth? In his new book, science journalist and math expert Holger Dambeck presents 100 new puzzles to get you thinking.

Just like in traveling, the journey is often the reward in mathematics. Unlike many school assignments, Holger Dambeck's math puzzles therefore do not provide solutions, but invite readers to go on a journey of discovery themselves. After all, solutions need to be found and this requires creativity, alertness and a love of the unknown.

Following the great success of his two puzzle books Three Logicians Walk Into A Bar and Blind Date with Two Unknowns, Holger Dambeck now presents his latest collection of 100 clever math puzzles in Being Cross With the Square
