"Problem Solving in Shangri-La"
Hacker’s plan to clone himself — so he can wreak havoc throughout Cyberspace in many places at once — goes haywire when his newly invented Clonitron clones Delete instead of himself. But Hacker takes advantage of the mishap by sending the Delete clones to take over the R-Fair City cybersite. To complicate matters, every time Delete sneezes his clones multiply even more. As the problem escalates, the kids do the math to keep track of the number of clones as they increase. Meanwhile, Cy Clone, a famous clone catcher sent to the site by Motherboard, vacuums up the clones, while Digit tries to get the Clonitron away from Hacker.
