Inhaltsangabe

These 99 number-crunching puzzles are sudoku PLUS! Just like the familiar sudoku that solvers love, the grids go from 1 to 9, and each number appears only once in each row, column, and box. The twist is, you need to do a little arithmetic, too—multiplying, dividing, adding, and subtracting according to the signs in the grid. It’s a fresh, challenging, and mathy take on the super-popular puzzles.

Über die Autorin bzw. den Autor

James Liber was born in Toledo, Ohio, and has lived in Hillsboro, Oregon, since 2000. A sports fan, Liber has enjoyed working with numbers since he was about eight years old, when he would figure batting averages, shooting percentages, yards per carry, etc. In 2006, he decided to add a little simple maths to the non- mathematical sudoku puzzles - and Number-Crunching Sudoku was born. This is his first book.
