Using a Number Line for Subtraction | Cyberchase

Use a number line to solve a subtraction problem. In this video from Cyberchase, Buzz and Delete are determined to make it into the Cyber Book of Records for the “Two Bot Mop Hop and Flop” and the record to beat is 23 cyber units from the starting line. The competition takes place on a field with a number line, each hashmark representing one unit of distance. With each attempt, Buzz and Delete use the number line to measure and compare distances, illustrating how subtraction helps determine how much farther they need to go.
