Suppose you are a principal of a school and you have to select a Mathematics teacher. It is obvious that you will interview the candidates. If one teacher says that 2 2 = 3, the other says 2 2 = 4 and the third says 2 2 = 5 whom will you select? Since you know mathematics is logical, you will never select or allow a person to teach mathematics who doesn%u2019t even know the basics of arithmetic that 2 2 = 4
