What is this American “college algebra”?

>>11147803

>Systems of equations (as time permits)
holy kek

>>11147823
They want to focus on the most important stuff first

>>11147791
Learn the rules of equation and inequalities and post your notebook

>>11147838
Well there is worse.
The first year math textbook for the tech school I went to started with counting on a number line and ended with Laplace transforms. It was a terrible book, and now in 11th edition.

>>11147860
>counting to calculus
How many pages was the book?

>>11147867
Not counting the answer section it’s 1001.

College algebra was just high school revision for me. Should be the same for Americans no?

Even Introductory Linear Algebra was mostly stuff i learned at A-Level with just a little but more rigor.

They teach algebra is college?

>>11147815
Damn, I don't want to be mean but high school students who past algebra 1 can do this.

All you have to do is remember things. What the fuck

>>11147943
>just remember it bro
great advice

>>11147909
Why wouldn't they? If you're going back to school after five+ years, even if you had a proper math HS education, it's probably a good idea to take some 9 week refresher precalc course over jumping right into calc 3

Though I don't know why some colleges separate college algebra, trig, and pre-calculus into three different courses. That's just insulting.

>>11147958
>I don't know why some colleges separate college algebra, trig, and pre-calculus into three different courses
My community college does this. The university I'm transferring to doesn't. I didn't take trig in high school and it's been years since I did algebra, so that's what I got placed into.

I'm teaching myself trig/precalc stuff so I can try and at least skip trig, if not go straight into calc 1 from algebra

>>11147803
It's the same algebra you learn in middle school if you're European or Asian.
They teach it to middle schoolers here too, but since everything caters to the lowest common denominator, they repeat it in high school in case they didn't learn it in elementary and middle school, then they repeat it again in college in case you didn't learn it in high school.
It's a prerequisite course for harder physics and math classes, and a requirement for many degrees, even non-math ones, but lately some places have been giving students in the arts or humanities a way around that.

>>11147905
It is material that literal 12-year-olds can grasp, but it's also not safe to assume that any given college student actually had adequate exposure to it as a teenager.

>>11147954
It's not advice. I'm saying literally all algebra is, is remembering a few simple rules. You don't even have to put thought into it

>>11147791
Is it because you are lazy or because you find it difficult? Even if it's because you find it difficult you might need to put more time in to make sure you understand the concepts.

>>11148234
Really should have defined the difference between a subset and a proper subset there. That's just some lazy shit that'll mess you up with the symbols.

>>11147791
you'll fail for sure if you keep spamming the same thread every goddamn day instead of studying

>>11148234
im fully convinced that shit handwriting correlates with being a dumbass

>>11148297
Do you think this is a joke? It's tanking my GPA

>>11148297
I've noticed the opposite, at least when it comes to males. Then again, all of them lazy.

>>11148308
Do you want help? We need more data.

>>11148314
how do i remember stuff? i study and study but it doesnt stick

>>11148308
>Computer science
No wonder you're a retard.
You know that you're not gonna make video games, yeah?

>>11148329
When it comes to math, I’d recommend one tries to understand rather than memorize. But if you want to go that route, spaced repetition is the best way to memorize anything.

>>11147791
im failing stochastics bros, i had no problem with other stuff like analysis or linalg. it just seems so unintuitive. any advice?

>>11148169
You may joke about failing arithmetic but in my college the elementary teachers have to take a “higher arithmetic” class that is basically elementary number theory for retards. The entire class involves the 6 laws of algebra and number systems. It is entirely possible to fail “college arithmetic”

>>11147803
>>11147815
Even in America it's a class you only take if you're an absolute brainlet. Literally everything in it could be learned in 2 weeks. I remember taking it in my first year of high school, literal snoozefest.

>>11147791
drop out of college its not worth it
t. ms in cs

>>11147958
i felt precalc was more difficult than calc 1 2 and 3. i got a D in hs and As in calc

>>11147791
science majors are almost completely useless. if you want to work with computers just go into something like GIS

Nah OP, you’re just a fucking idiot, enjoy Taylor series if you ever get let into calc

what is H O S and T?

>>11148614
grind it out and don’t specialize in it if given the choice.

Post your country's GDP

>>11148308
you might want to drop out of college if you can't keep up with middle school math. or at least cut out the time you spend on other classes to really get things down right now. this is like 2+2=4 lvl stuff you should have an A in the class

>>11149470
H quaternions, O octonions, S sedenions, T no idea

>>11147791
What is so hard about it?

>>11149470
>>11149644
T is probably tessarines

>>11148308
You go to CCRI, and you're about as brainlet as the other people there

>>11147791
lol

i failed college calculus but kept going to class because there was the most beautiful blonde who i sat next to. she kinda looked like pic related but less jewish

>>11149672
tessarines don't contain S, O and H

>>11147815
dont you learn this in highschool? lol

>>11150270
>less jewish
>think it's a good thing

It's a science board

>>11151814
there should be a mandatory math entrance exam and if you can't self-study high school math and pass it you should be deemed too retarded to go to university and denied entry. but it's basically a money making scheme so whatever

I can type 200wpm so whenever i have to write things down i do it extra sloppy because fuck that shit it takes too long

>Together we will examine some of the important and representative writers from across a wide array of ethnic traditions, including, African, Asian, and Anglo American, Latina/o, and American Indian, whose work collectively paints a more inclusive and fully realized picture of American life in the late 20th and 21st centuries. The course will ask two basic questions: what does it mean to be an American? and how does culture both represent and create that experience?
>Authors we will study may include: Oscar Casares, John Lewis, Gene Yang, Sherman Alexie, Leslie Marmon Silko, Maria Helena Viramontes, Jhumpa Lahiri, ZZ Packer, Jordan Peele, Alice Walker, Mia Alvar, and others.

It's a euphemism for high school algebra so as to keep brainlets from being discouraged and dropping out of their humanities curriculum. They try to teach this to you in high school but they begrudgingly let you graduate without it if they can't beat it into your head, and any person with half a brain who didn't take it in high school for whatever reason (I personally dropped out sophomore year to start college at 16 with GED) can just test out of it and go straight into calculus (elementary analysis) or linear algebra etc immediately.

>>11147958
In my state college algebra is a 3 hour a week course, trig is 2 hour a week, and pre calc is 4 or 5 hours a week and combines the two. you can take college alg and trig simultaneously, one per semester, or just take precalc. Or not be a retard and just take calculus

>>11148297
>not inventing an english writing system to simplify writing in order to write fast with less care for neatness
NGMI

Europe has that algebra in high school. If you study harder, it is doable

/sci/ should have a fucking entrance exam, we are getting more and more low iq brainlets every day.

And also people who think they're smart when they're doing a degree in Lindsey morris college.

Honestly I don't see how people fail anything below analysis these days. There's just so many resources available online for anything below junior year undergrad math.

It's not even IQ issue, it's a motivation problem.

>>11148234
lol wtf

>>11154399
"College Algebra" is a euphemism, because many freshmen have to take it as a remedial course. We learn it in high school too.

I guess it's the Trigintaduonions.

>>11154413
>And also people who think they're smart when they're doing a degree in Lindsey morris college.

A lot of successful people didn't go to the best undergrad universities, because they weren't wise and experienced enough as teenagers to decide that they really want to learn things, so their grades weren't good enough to go to an ivy league.The system is aware that teenagers are unstable, and the system also gives you several chances to improve, such as going to a better grad school if you do well in undergrad, or being a postdoc for a while if you didn't do perfect in undergrad.

>>11147973
stop trying to build the wrong perception tard, not every school like this, and some good public schools, like mine, probably have 60% of its students taking AP Cacl AB senior year. Although the cheating rate is really high too due to asians which I hate.

>>11148359
if you don't enjoy math, you don't belong in a university in my opinion

>>11152174
it's called the SAT

>>11148297
Not that I'd ever say it IRL, but I have to agree. One of my fellow phd students in my research group has absolutely horrible handwriting, basically like an elementary schooler's, and his work is by far the weakest.

They should just call this course: "hello stupid, thanks for your money!". god americans really are dumb.

>-1*-1=1

fail it twice and you'll pass

>>11156313
Wrong operator.
>-1+-1=-2
Fail it twice and you'll need to pass twice just to get back to where you started.

calculus next semester bros im gonna make it

>>11147815
holy shit this has to be a joke. Im going to teach my own kids, leaving them to the pit of despair that is public schools these days would be my greatest mistake

>>11147860
>>11147878

lol holy fuck. I don't know what more impressive. That they started at the number line and got to laplace transforms or that it took them 1000 pages to get there.

>>11148827
>the 6 laws of algebra and number systems
what are those?

>>11149644
aka, useless mathematician circlejerking

I'm fighting for my grade in Gen Chen 1.
I have to admit my study habits are shit because my retention is awful even when I feel like I get it.
I've had multiple mental breakdowns this semester just over grades and coursework.
I'm not sure I passed this exam. I got a C on the last one and I'll be happy to get a C in this class.
Even my TA has ripped me a new one. My lab notebook was shit at the start of this semester and I'll admit it, but this TA is just brutal and everyone knows it. I was kinda hoping my lab grade would boost my overall grade in the class, but no, I'm gonna have to fight for that too. Fuck, I'm not even sure I'm gonna pass the lab component.
This has been a bad semester for me. All I've eaten for like a month is ramen and junk food and I've been oscillating between anxiety and depression the whole way.
I even dropped a course before the second midterm.
I'm not okay.

>>11159262
yeah bro you're mentally ill you need to take out student loans to eat better food and HAVE SEX INCEL alright alright

>>11159291
The school and multiple students have suggested I just go on food stamps.

>>11156060
I enjoy mathematics just not the stupid useless shit that maths majors do. You don't need to understand any of that shit past linear algebra and multivariable calculus.

>>11159262
stop being a retard and get the easy 90% marks for oncourse assessment so you can get 30-40% on the final like I do and scrape by on a pass. Easy.

>>11159326
The final is 25% of my total grade AND it replaces my lowest test score.

>>11159340
Well it sounds like you're doing some meme degree like CS or something. Sorry about that. Better luck next emergent consciousness cycle.

>>11159262
Are you me? I never learned electron orbitals. Now we're doing IUPAC naming for hydrocarbons and all that shit and it doesn't make sense.

>>11147815
That's middle school material lol.

only IQs > 170 could learn all this in a single semester

>>11147815
AHAHAHAHAHAHAHAHAHAHAHAHA

Is /sci/ smart enough to teach math?
