Welcome to a new Bracketology feature here at Insider. Bracket Math provides an up-to-the-minute assessment of the entire Division I men's basketball landscape. You'll know who we'd put in the bracket -- and why -- at any given point of the season.

Bracket Math will increase in frequency on non-Bracketology days as we get into February and March, also appearing Wednesdays and Sundays starting the week of Feb. 7. And, of course, you can find it here daily (or even more frequently) during the frenzy that is Championship Week.

We know you want bracket updates as often as possible between now and Selection Sunday. When that's not practical, Bracket Math will always tell you where your team stands in the NCAA tournament selection process. We hope you like this new behind-the-scenes look into all things brackets!
