Trexagon Puzzles: Mathematically Logical

It's time to put your mathematical and logical skills to the test. A Trexagon puzzle consists of 21 triangles. Place a digit from 1-7 into each triangle so no digit is repeated within a horizontal row or any diagonal in any direction. The triangles are subdivided into zones, each of which has a desired value and a mathematical operation (add, subtract, multiply, and divide). The mathematical expressions associated with each zone determine the digits to place in each triangle. Using just your wits and the information provided by an empty puzzle, you must place 21 digits to arrive at the unique solution.With over 50 Trexagon puzzles, this book will provide hours of challenging puzzle solving.
