In the video, two men argue over how many donuts each officer gets if there are 7 officers and 28 donuts. The first man says that each officer gets 13 donuts each, while the other argues against him. At the end of the video, on there last attempt, the two simply take 7 13's and add them up. All they did was add each of the digits, when they really needed to add the actual numbers themselves, meaning they need to remember the differance between the ones and tens. For each officer to actually get 13 donuts, the chef would have to bake 91 donuts.
