The CyberSquad is having trouble keeping track of Buzz and Delete's moves, so Inez suggests they determine the floor that Buzz and Delete are on and go directly there instead of following each individual move. She draws a number line to make it easier to find out where the two villains are. The villains' most recent moves confuse the group, as they end up below the ground floor. Matt, Inez, and Jackie realize that they need to travel to negative floor numbers and define negative numbers for the confused Digit.
