THE LOGIC PUZZLE THAT MAKES YOU SMARTER.

Rules:

1. Each row and column must contain the numbers 1 through 5 without repeating.

2. The numbers within the heavily outlined set of squares, called cages, must combine (in any order) to produce the target number in the top corner of the cage using the mathematical operation indicated.

3. Cages with just one box should be filled in with the target number in the top corner. A number can be repeated within a cage as long as it is not in the same row or column.
