work is fun

 I came here at 14 hrs. Today I talked about Prime numbers, Sieve of Eratosthenese, Went over Gauss's method of addition and  how this idea can be used to count the pizza slices then how to count the number of squares in a grid and how this leads to the idea of counting the sum of square numbers. I also introduced the idea of Josephus Problem and the assignment is to work out the solution for that problem when there are 21 students, 100 student and 1009 students
