The Math Thread!

Isn't it reflective?


I'm learning about the converse of the Corresponding Angles Postulate.

... how is that transitive? XD

That's what my math teacher told me... I think. I need to check my notes. Right back, guys.

Ok, ok, never mind!
a=b and b=c then a=c is the Transitive axiom of equality!
 
I can't say that I'm a huge fan of math. It takes me full minutes to solve mental math problems like 42+76....=118?

Also, none of the three of my parents are helpful with it. As soon as I got to sixth grade they would look at my worksheets and say "Ask your teacher, I don't remember that."

By some miracle I've made it to Geometry (which is considered advanced if you have it in your freshman year), and thank goodness the students in there are smart and kind enough to help me out. :)
 
Pre-Algebra is the most pointless class one can take. I took it in fifth grade, because the school wouldn't let me Algebra I. Now I'm a sophomore in AP Calc AB when I easily could have been in BC.


If you get put it Pre-Al, definitely push to go to Al 1.

I'm in 8th grade, and I'm taking Geometry this year haha slick... jk.

It isn't that hard... but there is one thing I don't understand. I forget what it is though :p.

Same with you! Geometry at 8th.
I think Algebra was TOO easy. but then Geometry is a bit confusing and hard to memorize lol.
 
Wait so in the USA you get to take different "classes" for maths even in high school? Over here, in the UK, we don't get that sort of choice until sixth form, ie ages 16-18. Up until then it's simply just maths, with of course different sets for different abilities.
 
^Yes Hadders. In America, we take a progression of math classes that build on each other. It usually goes Algebra I -> Geometry -> Algebra II -> Triginometry (often combined with Algebra II now) -> Pre-Calculus -> Calculus. You can also take Statistics on the side if you care to. The path is linear and there is little deviation, but it can happen... the deviation is usually around pre-calc and calc (which is about the same time as your 6th form, or so I could infer). Also, Hadders gonna Had.


Aggie, the classes will only get harder. Make sure you know a large amount about your content and can do it very quickly. You'll need basic concepts in early math classes memorized and made into habits before you can even touch more advanced math.
 
As an aspiring math teacher, it's kind of amazing I haven't posted in this thread yet... derp.

In middle school I had one of the highest scores in my school on those standardized test things, and I was offered to take Algebra I in 8th grade. Of course, I wanted the easy A so I stayed in the regular math class, which of course I dominated.

High school comes along and again I have the option to take Algebra I as a freshman (which is the "default" path, so to speak) or I could take what they called "Core Math 1-A" which was basically a repeat of 8th grade math (there was a 1-B, but I don't know what it was for. Maybe for students who really struggled). Guess which one I took? -_-

Algebra II came after that, followed by Geometry my junior year. I don't even know if I took a math class my senior year. Probably not, now that I think of it - I had classes I had to retake and already satisfied my school's requirement for math credits.

Of course that means I have never taken a calculus or trigonometry class, two things I will definitely have to do in order to, y'know, not suck at life. My first semester at glorious community college, I took a class they called "Math & Logic" which is exactly what it sounds like. We worked with truth tables (those are fun), set theory (the devil), and at the end we had some basic algebra and stuff. It was pretty cool. Heard it was the hardest math course they had (passed with an A-) but this is community college and we DIDN'T TOUCH TRIG/CALC AT ALL LSFJLSGKHX.

neway.

It makes me a bit envious and also kind of happy to see those much younger than I not only have an interest in it, but be dern good at it too.

With math bosses like z-man and bacon around, I doubt I'll be helping much with people's math questions. But I will continue to lurk this thread and post on occasion.

ponies for life
 
I lost track of the Course Names I took after Calculus III really.
Linear Algebra and Higher Geometry, Math Modeling, Statistics I and II, and Vector Calculus

There is some trig in my Geometry class too.
 
^
Yeah, I just started a unit with some Trig in it too... It looks scary, there's all of these weird names and things...should be interesting.
 
Hey, i have a particular math problem here. During our study of exponential and logarithmic functions, I got a special equation i cannot solve. It s stated in the simple form as below:

a^x=x
or
a^x+x=0
a being obviously a constant.

I wonder if it s possible to solve this equation.
 
I m grade 11, but obviously, the teacher didn't ask a question like this.
Is there a solution?

my community college went up to Calculus III with Linear Algebra and Discrete as electives for math/cs/physics/engineering majors. I'm a social science major so I only went up to Calc I to fill a general requirement and now I'm in statistics. my girlfriend is a CS major with a math minor so I often get exposed to math I've never seen in random conversations. I don't understand a lot of it but oh well.

I used to actually be really good at math. in elementary school I had special math tutoring and was in accelerated math throughout middle school (unlike you, PMJ, I actually took Algebra I in 8th grade. you didn't miss much ;3). in high school I entered the honors math sequence but I started developing a lot of my current health problems and couldn't keep up with my classes, so I dropped down a sequence (from honors to accelerated) and still struggled to keep up. I went up to Precalculus in high school and didn't take a math for my senior year (as I didn't qualify for AP Calculus, only high-school level, and I was already part-time at the community college and didn't want to waste my time with something that didn't get me college credit). eventually I took a math placement test in college that to my surprise put me directly into Calculus I despite having not taken a math class for two years. I struggled with the course a bit, though in retrospect it was mostly due to the course being based around a program that I couldn't get used to (Mathcad the first time I tried the course and Wolfram Alpha's Mathematica the second time). now I'm in Elementary Statistics and so far that's been very easy, so that's nice. after that I might be done with math until grad school, as I'm a social science major.

look at that wall of text. tl;dr I took up to Calc I before switching to Stat and I'm okay at everything up to Calc I but if you need help, ask DNA or bacon
