These 99 number-crunching puzzles are sudoku PLUS! Just like the familiar sudoku that solvers love, the grids go from one to nine, with each number appearing only once in each row, column and box. The twist is that 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 mathematical take on the super-popular puzzles.
