For math geeks

Easy:
2X=24

Harder:
3X+4X-10=35

Hardest:
7X²+3X+5-2X²=18

Oh but don't worry, it'll get harder.

That's like saying 2+2 is easy, 2x2 is hard, and 2/2 is harder. Really?

I hate slow people. (poo poo poo I didn't mean that.)

  1. thanks for making a post for my type. Nu, can you solve them?

  2. ok here's how we learned how to solve them:

    2X=24 (X of course equals 12, but here's the long way)

    2/1x1/2 which gets canceled out.

    24/1x1/2=12

    X=12

    3X+4X-10=35

    :7X-10=35
    :7X=25
    :X= 3 4/7 (or a decimal, but I dont care to do that.)

    okay I can't do the last one, you try it.

  3. The last simplifies to 5x^2 +3x - 13 =0 and then you can either factor or use the quadratic formula.

    What context are these problems from?

  4. I'm tempted to say what the hell is quadratic formula.

    okay I'm in college level math. this is what we are learning. i believe i've learned all this already in elementary of high school. people in my class are stupid and it grates on my nerves.

    and the last problem, i just made it up randomly. i had no intentions, and still dont, of solving it.

  5. ok you are right, i do hate stupid ppl. and if that includes you, my apologies.

  6. what a lame save, you know that the math problem is real..wat u be lyin fo?

    ReplyDelete
  7. lol. of course it's real, and i'm sure it has an answer to it. i just have no intentions of solving it.

    now you solve it for me.

  9. You can't factor it because the numbers are prime.

  10. 2X=24 (X of course equals 12, but here's the long way)

    Math is opposite from davening. Doing it b'arichus is not better. :)

  11. i wish. according to my teacher, is we dont do it the long way and check, we get 2 points off.

    ReplyDelete
  12. Because your teacher doesn't want you to cheat or make stupid mistakes. Plus, if he/she is like most teachers of the world, he/she doesn't want you to be too smart. But it's worth it to develop the ability to think in your head.

    I drove all my teachers crazy. Actually, I got bored half-way through my Calc II final, guessed the answers to the rest of questions and left early. I still got B+, but this was when I realized that Math was probably not for me.

  13. lol. okay well, the teacher takes 10 minutes to solve a 2 minute problem. and to have half the class saying 'what, i dont get it, i got it wrong.' and some other girls saying 'altie, what did u get? oh i got the same thing, it must be right!' and another girl told me i must be a genious. they are all idiots!!

    and i walked out of class and came back a half hour later and still knew what was going on, and that is a bad sign.

    and yes, teachers are stupid.

  14. Sounds like the school is too slow for you. Perhaps the solution is to take a math tutor who will go ahead of the program with you. Or do so yourself.

    ReplyDelete
  15. our dearly beloved e tutored me. it didnt work.

    i hope to switch schools. this school is dumbed down for people.

    ReplyDelete
  16. Well, e is not the only tutor in the world, with all due respect. Just like with shidduch, there are always other options.

    ReplyDelete
  17. lol true. but he was the only math geek i knew. i was taking a test to go to higher level math. but i didnt pass cuz i didnt know all the stuff. all i know is that everything we are learning now i already know, plus the class goes really slow, and i cant stand it.

    ReplyDelete
  18. Is this high school or college? In any event, it seems to me you're wasting your time and, much worse, wasting your mind.

    I freaking hated school precisely because everyone around me was a moron. Including teachers. Having looked at the students from the other side, as a teacher (of sorts) myself, I still think so.

  19. in seventh grade, I remember my teacher taught us the quadratic formula song! It was the formula to the tune of Hot Crossed Buns.

    ReplyDelete
  20. and I still have no idea what hot crossed buns are

    ReplyDelete
  21. ok, it may actually have been the tune of baa baa black sheep.. not sure

  22. CA- thanks. college, but its not much of one. its a frum college and all women, never a good thing.

    yossi- lol. im sure u remember it to this day.

    ReplyDelete
  23. The frum part or all women part? What about Stern?

    ReplyDelete
  24. the frum part mainyly.

    stern is good, so i hear. i'm thinking of switching to like brooklyn college maybe (gasp! a frum girl going to a mixed non jewish college??? how is she gonna get married??) i know i know. we shall see.

  25. I was thinking about it. I think it’s more important for your marriage and life in general not to waste your time and, more importantly, not to waste your mind. Unless you want to marry someone who wants to marry a standard issue.

    ReplyDelete
  26. lol. you're still thinking about it? That's funny.

    I agree with you. Of course. You make a good point. And no, I am not a 'standard issue', nor do I want to marry someone who is.

    I can't believe I'm discussing my life with a complete stranger. The semester is about to end. I have no idea what I'm doing next. No idea at all. It's refreshing.

  27. What are blogs for?

    You should do what will maximize who you are today and whom you want to be tomorrow.

    ReplyDelete
  28. Someone once asked me what I wanna be/do when I 'grow up' and when I described it to him he said, 'a shlucha!'

    I have no idea. I don't like the idea of defining myself. I don't want to be limited to a little box. There is so much I can do, so why pick only one path? I want to be one of those ladies who are a stay at home mother, and yet do sooooooo much more then that. I want to do something with my writing. I want to help people. I want to do family counciling. I want to do so many things. I just have no idea how to GET there.

    I know who I want to be. It's the who I am NOW part thats a bit blury.

    And the funny thing about blogs is, I always wonder, why the hell would a complete stranger want to read about MY life? Sometimes even I want out of it. And a guy told me, 'cuz your life is interesting to read about.' Go figure.

    ReplyDelete
  29. Well, a University can be a preparation for narrowing down your life to a specific path or just something that will give you tools for doing whatever you want to do and being a more complete and prepared person. You are a part of this world, and the more you know about it, the better you can do your job in it. This needs to be balanced with other things, of course, but this is the kavana.

    Which is not to say that getting “jack-of-all-trades”, buffet-style education is ideal.

    Another thing is: you’re wasting money. Not just your/your parents’ money, but money of the people who donated to the University, so that tuition can be a third of what it could be. This money could be used on someone else (for whom your college would be a better fit), who was rejected, because you were accepted. So, there are many problems with being in a place where you don’t belong (because you can do better).

    Sometimes blogs are mirrors.

    ReplyDelete
  30. So I should drop out so someone else can have my place?

    Wow, a whole new world has opened up to me! (sarcastic.)

    Many people dont go to college and are well educated smart people, with good jobs. (okay maybe not, but it sounds nice.)

    My grandparents want me to go to college. And the fact that I go to night classes is not enough for them, even though I'm considered a full time student. Now they want to know if I'm gonna go to college full time, during the day.

    I probably would never have even thought of going to college if i didnt feel like rebelling against the 'system' and breaking out of the stupid mold I've been put in all my life. Stupid, huh?

    Damn. I have class tonight, I'm suppposed to be writing an essay. On 'why is tv detriment to a childs natural creativity, and is likely to warp his moral perspectives.' Do you wanna write it for me? I'll give you a donut.

    ReplyDelete
  31. Back when I was taking classes, most students would ask: what’s the minimum word count for an essay? I would ask: what’s the upper limit.

    I think you should do thinks, because they make sense and create a positive change. Not stam azoy.

    Yeah, wasting money and time is stupid. Not commingling with opposite gender is a value that exists in Yiddishkeit (to what degree not to commingle — from zero contact to maybe not being best friends with a motog — that’s a separate question). Not wasting time, talent, intellect, opportunities and money (your and tzedaka money) is also a set of values. You have to decide where there is a bigger danger of a value being compromised (when I went to college I was very anti-social, so I didn’t commingle with anyone at all... so there was no danger there :), and which value is more important at this point.

  32. oh shoot, I have to THINK? what is the world coming to?

    I take it thats a no on the donut.

    in public schools they have guidance counslors, and if they are any help at all, they help you figure out your life, your career goals, and what you should do next. in the religious world, there is seminary. it helps you figure out what kimd of mother you will be, what kind of shlucha you will be, what kind of teacher you want to be, etc etc etc. talk about molds. like jello.

    to me, the future is tomorrow. thats as far as i've gotten. i cant think too far aead, i get a mental block. i think im gonna eat your donut.

    so how is your life turning out?

  33. google has failed me. what does that mean?

    ReplyDelete
  34. It's very big of you to admit that. Now I feel better about my life. On the other hand, if a smart person like you is ignorant, then there is no hope for the rest of us.

    As my smart but bitchy and stuck up brother always says when i call him an idiot, 'if i'm stupid, then the rest of the world is brain dead.'

    ReplyDelete
  35. I didn’t say I am stupid; I said I am ignorant.

    Good for your brother.

    ReplyDelete
  36. no, bad for him. its better to be a nice person then to be smart. luckily, i'm both.

    so lets say like this: the world is filled with lots of knowledge. we only live for X amount of years. in those years, how much knowledge does the average person ingest? and how much is possible? you can learn and learn forever, and still not know anything. the trick is to pick and choose whats importsnt to learn, and what is useless knowledge. if you dont have that ability, youre effed.

    learning is a good thing. but i dont like doing it.

  37. That’s too complicated an answer to give a recipe for.

    Maybe he’s being realistic. Rashbi said: “If there are two people who know Torah, it’s me and my son. If there is one person, it’s me.” Rava’s students said: “Teacher, you killed the world.”

    ReplyDelete
  38. okay, okay. so, you can be smart without rubbing it in everyones face. and demeaning everyone else in the process.

    to say, you are smart, but i am smarter, may be true, even if it may not be so nice. but to say, i am smart, you are stupid, and there is no hope for you is just plain mean.

    see, dont limit people.

    and anyway, i'm not looking for an answer. most of the time i'm not. when i ask questions they are either rhetorical, or self musings.
