In this video segment from Cyberchase, the CyberSquad must build a rail line to get around the mountain to transport flowers gathered from Thornium Mountain. To do this they must complete decimal addition to figure out how long to make the new rail line. After looking at their sum, the CyberSquad believe that something is not quite right. They realize they did not line up the decimal points when they added the numbers, so they fix their mistake and add up the numbers again.
