Problem #1: Hello !!

In a group of 6 students, if each person says ‘hello’ to each of the other group members 1 time, how many total ‘hellos’ will be said in the group?

"What If?"
There are only 2 students?
3 students?
5 students?
7 students?
10 students?
n students?

Rather than "hellos", what if you counted handshakes?
