## Monster Cages #

*Difficulty: 2*

*Tags: Sudoku, Chaos Construction, Monster Cages*

This puzzle is a chaos construction. Cages indicate the product of each region sum contained in a cage. For instance, if a 4-cell cage contained 1,2 in one region and 3,4 in another region, its total would be (1+2)x(3+4)=80. Cages may be contained in one region, in which case, the total is just the sum of the cells. Digits may not repeat in a cage.

*Difficulty: 2*

Digits in cells separated by +, x, and = signs form valid arithmetic operations. (All arithmetic operations involve only one-digit numbers.) Classic sudoku rules apply.
