Codie

I was given a question, and it seems pretty easy but could someone check it for me? If there were thirty-two students in a class, and each shook hands with everyone else, how many total handshakes would there be? I got 496, can anyone else get that?

I don't exactly understand what needs to be done in this problem. Could someone please explain what I am supposed to be doing a bit clearer than the book? Four jobs need to be done, and four workers are available. The chart shows how long each worker take...

is this realy correct
