Before Cam Newton suits up for the New England Patriots, he has some homework to do. And he's already opened his textbook.
The veteran quarterback, who reportedly signed a one-year contract with New England in late June, shared a photo Tuesday via Instagram of himself with a cup of coffee and what appears to be the Patriots' playbook.
"This s--- calculus!!" Newton joked.

The Patriots have a notoriously complex playbook, and it appears Newton is finding that out after nine seasons in Carolina.

Our Tom E. Curran reported there's "no concern" in New England that Newton won't master his new offense, though, and the 31-year-old QB already digging into his playbook helps explain that confidence.
Newton also tagged Patriots wide receiver Julian Edelman, the team's longest-tenured offensive player (not counting special teamer Matthew Slater). Edelman responded on Instagram with his own acknowledgment that figuring out New England's playbook is like decoding a tricky math problem.
If Newton can return to full health after undergoing offseason foot surgery and pick up the offense quickly, that should add up to a successful season for the three-time Pro Bowler and 2015 NFL MVP.
