Sam and Amber are playing a computer simulation game, rescuing Wattbots from a danger zone. Amber causes them to lose the game because she left two Wattbots behind. Numberella explains how Amber, making the last rescue, should have rounded up the answer and sent in four ships to make sure all the Wattbots escaped. Numberella reminds the children that they should always look back at the original question and make sure the answer makes sense.
