A number cannot be repeated within any row or column. The heavily-outlined areas are called cages. The small number in the upper-left corner of each cage is our target number. The math symbol next to the target number tells us which operation we'll be using in that cage Cages that are around only one square are the easiest to solve. The target number is the number that goes in the square. KenKen was suggested on my Sudoku project so I made it!
