HELP! playing piano notes

[mirrorcleworld]

umm I was just wondering if someone here who knows how to play the piano could help me out?
i'm currently learning how to play the piano (i pay for every lesson to a tutor) but i haven't yet reached the lesson on how to play beamed notes (or so wikipedia says) like this:



i've paid for only 4 lessons, and the last one is gonna be my last until I continue my lessons again on June

so if anyone here could explain to me everything there is to know about those notes above and how to play them, please do tell me! thanks!!~~~
