One day a little Integoolie named Ned decided to go outside for a walk. As usual he had to solve an integer question to open his door. Today's question was a really simple addition question. So simple in fact that he decided to just do the math right in his head.
Ned found some circular rocks, 5 blue and 3 white, and arranged them in two lines, 1 with blues and 1 with whites. He then explained that a blue rock represents a positive number while a white rock represents a negative number. He also explained that a blue rock and a white rock makes a zero pair and that zero pairs equal zero. After that he explained that all you have to do is make zero pairs and then what isn't in a zero pair is your answer.
Ned was getting hungry from all his good deeds and he decided to go for lunch at Posi-Neg's Diner. When he got there he went to the lunch vendor and of course there was a problem on the vendor that he would have to answer.
Ned said to Norman that subtraction is a myth! All you do is add the opposite! Although Norman was puzzled when Ned said this he decided to go along with it. Ned then showed Norman how to do it on his own.
Once he got home he found Norman again who was trying to open their door. The puzzle on it wasn't very hard for Ned because it was just a question with both addition and subtraction.
He did however teach Ned how to do questions like these for future reference.
