NUMB3RS (pronounced Numbers) is an American television show produced by brothers Ridley and Tony Scott. It follows FBI Special Agent Don Eppes (Rob Morrow) and his mathematical genius brother, Charlie Eppes (David Krumholtz), who helps Don solve crimes for the FBI. It was created by Nicolas Falacci and Cheryl Heuton, produced by CBS Paramount Network Television, and airs on the CBS network in the U.S. It is also shown on Five US and ITV3 in the U.K, although it was also shown during a late-night slot on the main ITV Network for a brief period of time.

The show focuses equally on the relationships between 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 described by Charlie, with the help of Larry Fleinhardt (Peter MacNicol) and/or Amita Ramanujan (Navi Rawat). The insights provided by Charlie's mathematics are always in some way crucial to solving the crime.

The series was the most popular show airing on Friday evenings throughout its first three seasons; the fourth season began on September 28, 2007.

In the Los Angeles office of the Federal Bureau of Investigation, Special Agent Don Eppes and his team investigate critical and baffling crimes with a special edge. That advantage is Don's brother, Charlies Eppes, a brilliant universalist mathematician who uses the science of mathematics with its complex equations to ferret out the most tricky criminals. With this team, the forces of evil learn their number is up. Written by Kenneth Chisholm (kchishol@rogers.com)
