How to solve mathdoku (aka Kenken):
The 'MATH' part: The puzzle is broken into several areas inside bold lines which are called cages. The numbers that go into the cages must solve the simple calculation written in the cage.
Addition: The 2 (or more) numbers add up to the number in the cage. If the cage says 3+ the solution numbers must be 1 and 2.
Subtraction: One of the numbers subtracted from the other one equals the number in the cage. If the cage says [5-] then the solution numbers must be 7 and 2 OR 6 and 1 (in any order).
Multiplication: The two (or more) numbers multiplied by each other equals the number in the cage. If a cage with two boxes says 6x for example, the numbers would be 1 and 6 OR 2 and 3.
Division: One of the numbers divided by the other equals the cage number. For example, a cage that says 5/ would only have 1 and 5 ( in any order) as a solution.
The 'DOKU' part: As in sudoku, every number - 1 through 7 in this puzzle - must be used only once in every column or row.
Enjoy!
