The Mathematical Game of KenKen: Sudoku on Steroids

To start off, I would like to give an update on Tau 2000. This past Sunday, I established the world record my reciting from memory 2012 digits of tau, raising over $3000 dollars for the Bethel Public Library. You can find out how the event went at, or check out this video:

A part of the Tau 2000 event was the KenKen contest, which has contestants and even finalists who had never played KenKen before this event. This was true proof to me about how simple it is to learn that I had to write a post on it.
In short, KenKen is basically Sudoku on steroids. It has the same rules as Sudoku in that you cannot repeat a number in any row or column. However, it does not start you with any numbers like Sudoku does. Rather, it gives mathematical operations to help you solve the puzzle.

Here is a video to teach you how to play KenKen done by the crossword puzzle editor of the New York Times: Will Shortz.

It's pretty simple right? And once you start trying it, it becomes addictive. Here is a sample puzzle to get you started:

I will post the answer to this puzzle in a month, as usual with puzzles. For more puzzles, you can check out
