Numbers (stylized as NUMB3RS) is an American crime drama television series that ran on CBS from January 23, 2005, to March 12, 2010. The series was created by Nicolas Falacci and Cheryl Heuton, and follows FBI Special Agent Don Eppes (Rob Morrow) and his brother Charlie Eppes (David Krumholtz), a college mathematics professor and prodigy who helps Don solve crimes for the FBI. Brothers Ridley and Tony Scott produced Numbers; its production companies are the Scott brothers' Scott Free Productions and CBS Television Studios (originally Paramount Network Television, and later CBS Paramount Network Television).
The show focuses equally on the relationships among Don Eppes, his brother Charlie Eppes, and their father, Alan Eppes (Judd Hirsch), and on the brothers' efforts to fight crime, normally in Los Angeles. A typical episode begins with a crime, which is subsequently investigated by a team of FBI agents led by Don and mathematically modeled by Charlie, with the help of Larry Fleinhardt (Peter MacNicol) and Amita Ramanujan (Navi Rawat). The insights provided by Charlie's mathematics were always in some way crucial to solving the crime.
