    Ok you are in a room th a group of people. Everybody in the room shakes hands with everyone else once.

    Altogether 45 handshakes happen.

    How many people are in the room?

    Well there are 10 people in the room

    meaning you must shake has with nine each

    totalling 90

    but.......

    each person has cancel out one of the handshakes each halfing the overall total to 45

    i didnt google it, its god damn obvious lmao


    2 peepz for 1 handshake, 3 people gives 2 more handshakes which makes 3 peepz, then another person gives 3 more so 6 handshakes, another dude gvies 4 more, the next gives 5 more etc etc. eventually 10 peeps make 45

    very basic stuff
