I tutor math grades 4-8 or so, and I got a question that involved the prime f of a set. I wound up having to pass it on because frantic googling only came up with abstract bits and something about inversions. Can anyone point me towards an easier-to-understand explanation of how it works? :|a

Don't know/don't care: SO MY 21ST BIRTHDAY IS COMING UP. :D What did you do/plan to do for yours?

I was looking for this website that apparently you put in any equation and it solves it for you and explains how to find the answer... but I can't find it, sorry :(

My husband rented my girlfriends and I a limo. That was awesome.
We went out drinking and I didn't have to pay for ANY alcohol. That was awesome.

What wasn't awesome was that my best friend said she would make my cake. She didn't. And didn't tell me. I just noticed she didn't have one with her when she showed up. I never said anything but it made me feel crummy because my mom offered to make it if no one else did and my husband (only bf at the time) said if he knew he would have had one waiting in the limo.

What also wasn't awesome was I was expecting about a zillion people to show up to my birthday party. Okat not a zillion. But like.. 25 at least! annndddd.. 4 showed? So I bought all this food and drink stuff and nothing..

What wasn't awesome as well is that my husband came home from work (yeah also not awesome he didn't take it off) to me just a mess and drunk because I felt so rejected that day.

I'm almost certain that was the the plot of one of the Big Bang episodes.

I went out to dinner with my boyfriend, had one beer with my meal, then went home and went right to bed because I had work in the morning. Wildest birthday ever

no clue.

for my 21st my two best friends and i went to wisconsin (liquor laws are less strict than minnesota and at the time, indoor smoking in bars was still legal in WI but not in the majority of bars in minnesota, if it was a bar in minneapolis which is where i would've wanted to go, it was illegal, in st. paul at the time, it was still legal) and intended on bar hopping but it was more like me getting wasted (but having a blast) and needing one of my friends in front of me by the end of the night to keep me from sliding off my barstool, lmao. they made me wear a tacky crown that said "21st birthday buy me a drink" and oh god, people did. plus they had all these glow necklaces on me and mardi gras beads they made me wear. i was embarrassed to wear them at first until i was drunk enough (and realized the crown = lots of free drinks) that i gave no fucks. there was one couple, had to be in their late 40s or early 50s that omg kept buying me drinks left and right. and then all of the shots and beers. i was trashed, but i remember it all aside from some hazy parts. it was a good 21st. my friends and i didn't live far from the MN/WI border at that time so we took a cab there and back and it wasn't too expensive. we crashed at my friend's place who lived closest, haha.
