What is "cyberchase"

Cyberchase is an American–Canadian animated television series on PBS Kids. The series focuses around three Earth kids, Jackie, Matt, and Inez, who are brought into Cyberspace, a digital universe, to protect it from the evil Hacker. Using math in application with problem-solving skills, environment and weather, they are able to prevent Hacker from causing any more harm. In Cyberspace, they meet Digit, a cybird that helps the kids on their mission.

Cyberchase was created by Thirteen. It was first shown on WNET as a "sneak peek" on March 24, 2000, before making its official debut on January 21, 2002. In 2010, after the season eight finale, PBS put the series on hiatus, but it returned in 2013 for a ninth season, followed by a tenth season in 2015.
