Today Le has an assignment: to write the discipline about the following formulas,3²-1=8, 5²-3²=16, 7²-5²=24. Then he looks for answer with his mobile phone, and writes n(n-1). I give him a great cross. Then he asks how to answer. I say you should find the rule of the feature’s changing. Without a minute he says he can’t find. Le’s absent thinking annoys me. Then I try to ask his brother Heng. Heng says the former feature is bigger than the latter for 2. I say to Le,”Your younger brother is better than you.”
