Rules:
Normal sudoku rules apply.
Each circled cell with two arrows contains a digit N, and points to two cells N steps away in the indicated directions. The value of N is equal to one of the four basic mathematical operations acting on the two referenced cells.
- Addition: N is equal to the sum of the two digits
- Subtraction: N is equal to the difference between the two digits
- Multiplication: N is equal to the product of the two digits
- Division: N is equal to the largest of the two digits divided by the other.
One circle has its operation given, the rest must be deduced.
No two circles with a direct line of sight between them (horizontally or vertically) can have the same operation.
Line of sight is blocked by other circles.
A key has been provided next to the grid for potential note taking.
Note that it's possible for a circle to have more than one valid operation when filled in.
Enjoy!
