Featured Puzzle: Calcudoku #1

Calcudoku is the generic name for a Sudoku variant known better by the trademarked titles KenKen or Kendoku. To make things a little easier, I color-coded regions with the same math operation.

• Fill in the grid with the numbers 1-9 so that no digit repeats in any row or column.
• Within each region, the correct digits must achieve the given total using only the mathematical operator shown.
• Where an operator is not given, you must determine which single operation to use.
• Unlike Killer Sudoku, you may repeat a digit in the same region as long as it isn’t in the same row or column.
