Numb3rs season 3
By chance mom notice that this series is in its third season. She does not watch it but I loved it.
At first it is because of all these mathematical logics of solving things. But when I get to know all the characters, I can't wait to see how the relationships go. Such as between Charlie and Amita - tonight was good because it has focused on them.
And I was pleasantly surprise that Megan was interested in Charlie's colleague. I thought that it would happen with Don.
Anyway, here is a good website where they list down all the different algorithms and logic which was used in the series from seasons 1 to 3. Plus it has many activities to understand them. Enjoy them.
