Shaken, Not Stirred

Title: Shaken, Not Stirred
Rating: 4/5 

This is the last puzzle I've created.  It's a mix puzzle to finish out the run.  It's been a nice two-plus years, and this set of puzzles concludes posting on my wedding anniversary.  The title, I should probably mention, is just coincidence.   


The official rules:

  • The digits 1 through 9 appear in each row and each column exactly once.
  • Digits in each shaded region must add to the indicated sum (denoted by +) or multiply to the indicated product (denoted by *).   
  • Squares with multiple colors contain a number that’s used in the sum/product for adjacent regions of each of those colors.  
  • Remember: numbers can repeat within a shaded region if that repetition doesn't violate the first rule.
