Now that we have completed analysis tasks, I would like to revisit math necessary to comprehend the rest of the CS topics you will be encountering. Each group of 3 people should write down their answers to the following questions. I do not want references to some mathematical theorem. I want your own easy to understand explanations that would make sense even to 8 year olds. PRINT NAMES 1. We have learned that Sum of Kask varies from 1 to N is 1+2+3+...+N = N(N+1)/2 Why do you think it is N(N+1)/2 ? Explain. (Hint: draw bar graphs within a rectangle) 2. We have learned that there are N(N-1)/2 pairs when you have N elements. Why do you think it is N(N-1)/2 ? Explain. (Hint: draw dots and pair them up with lines) 3. We have learned that there are AAN ways to assign one of A values to each of the N people. Why do you think it is ANN? Explain
