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.
The CyberSquad finds that no one is on floor -3, and Motherboard cannot track their location. Jackie guesses that they are on floor -5, the Grand Ballroom, so Digit tries to determine which direction to go. Initially, he thinks that they should go up, but that turns out to be incorrect. Jackie, Inez, and Matt explain to Digit why -5 is less than -3.
High school teacher Mr. Jaime Escalante teaches his students about negative and positive numbers. He uses a real-world example of digging into sand at the beach to help students understand the concept.
