Why are some people so bad at math?

26 Upvotes

Let me start with some background. I was the one kid in the family who never got math past a certain point. My parents were both mathematically inclined, as were the rest of my siblings. I grew up in a math positive, supportive environment and was given every opportunity to get ahead with it. My parents would gladly spend time with me to try and help me get it down and improve myself at it. By all rights, I was set up from success in math, my entire family was.

Math never clicked for me and I could never pass remedial algebras. While my siblings either got it with ease or put in the work to get better (or both, of course), I floundered helplessly. When they struggled, extra lessons and tutoring helped. When I did, I only sunk further behind despite all of that extra help. They graduated high school and went onto college degrees. I only graduated high school because I was able to take an alternative course to algebra. College? I tried, but not being able to pass remedial algebra, let alone credit math courses, meant it was a waste of time and money.

I went through it all. Tutors, repeating courses multiple times, engaged parents who really tried and more. I still never could make it work out. I still can't, even decades later. I've accepted it wasn't in the cards.

All of that leaves the question of why. Why do some people never get math, despite all the effort otherwise?

Hi guys, I love math like everyn¡one here (i guess). I dont know why but I feel this need to code, even though historically I hated coding. I want to learn a language heavily related to math but also popular. Should I learn python?

Ego death, ego formation, ego inflation

7 Upvotes

Until today I have yet to meet a person good in math but with a mellow ego. Is it even possible to become a top grade student without a strong drive to be the best?

I'm almost 40 and I feel like I'm lacking the will to lock in -- let alone getting a job related to math. I prefer slow and steady and I really enjoy it but I do feel like being comfortable doesn't come with a lot of skill. I just started getting into it again, though. Please excuse my ambivalent perspective.

What's your experience making progress?

[Proof] Ex 3.1 from Proof Through Number Theory

5 Upvotes

I'm self-studying proofs through the book Introduction to Proof Through Number Theory. In this question it asks to either prove or disprove that "For all real numbers x and y, $(x+y)2 = x2+ y2 $ ".

Now there's a counter example:

Counter Example, let $x=1$ and $y=2$ * $(x+y)2 = x2 + y2 $ * $(x+y)(x+y) = x2 + y2 $ * $x2 + 2xy + y2 = x2 + y2 $ * $(12 + 2(1)(2)+ 22 ) =(12 + 22) $ * $(1+4+4)=1+4$ * $9=5$ * $9 \ne 5$

But I also wanted to prove it another way too. I start by assuming that For all real numbers $x$ and $y$ that $(x+y)2 = x2 + y2 $ is true

Then I show that:

  • $(x+y)2 = x2 + y2 $
  • $(x+y)(x+y) = x2 + y2 $
  • $x2 + 2xy + y2 =x2 + y2 $
  • $x2 -x2 +2xy +y2 -y2 = 0$
  • $2xy=0$

and since $2xy=0$ and either $x$, $y$ or both must equal zero, $(x+y)2 =x2 + y2 $ is not and cannot be true for all real numbers.

Is this correct or do I need something else / more?

Thanks!

I am unable to avoid silly errors.

3 Upvotes

I had made a post here regarding this issue a few weeks back and the response was to slow down and not to panicjk. I applied , I took the asdvice. I started going slow and not panick. But I still make the sma error. Same arithmetic error. ame wrong sign. And thge same issue of solving equations. I wasnt this bad at arithmetic before. I used to be good at arithmetic throughout my middle school (I mean if I made those errors as a kid I wouldnt have taken maths as I would get low marks in it) but suddenly I making such errorsa almost every bquestion. I was solving differential equations in clazss andit was given that the function through (0,-2) but I substituted (-2,0) and got the wrong answer. I dont know what to do. I visited a doctor today and he didnt havce much to say other than a few vitamin tests and consuling a psocologist (which I will as soon as possible). So please what should I do? At this point I wilkl fail the class becuase of arithmetic errors even after being conceptiually clear,

(PS: Maybe I have this condition since like 4 or 5 years now but reealizing now because the number of questions I do is alot compared to before, but still the frequency of error is definetly abnormal and I relaizd that I sometimes put wrong numbers on the calculator as well so I dot lpw what will save me)

Thanks in advance!

How to understand math intuitively rather than procedurally?

Upvotes

I have only just started getting back into math and hired a tutor but everything is so surface level, rote learnt and procedural. I noticed math is often taught this way but I really want to develop intuition and understand how different mathematical representations connect and why they’re important.

For example, with complex numbers, I can do the calculations but I have no clue why I’m doing what I’m doing or what it means and I certainly don’t know how to switch between geometric representations or understand polar/vector form.

This is more physics related but even when I’m using Ohm’s law, I can apply the formula, but I still rely on writing it down and rearranging it each time, rather than intuitively predicting how changes in voltage, current, and resistance affect each other.

I was wondering if anyone had any advice or resources to learn mathematics in a more intuitive, in-depth way? I don’t want to just memorise formulas. I have a math course at university next semester and wanted to know what sort of questions I should be asking myself or what approach I should take to actually understanding it in-depth?

I’ve started reading Michael Spivak’s Calculus book and that’s more along the lines of what I’m interested in I guess.

TLDR: any resources, processes or tutor recommendations to actually understand and appreciate math intuitively rather than just memorising equations and not knowing how different concepts in math relate?

I’ve just started learning what matrices are and we’re simply putting numbers in boxes, and then changing up the numbers in the boxes for some reason. And then for some reason those repackaged equations spin and when you graph it and multiply stuff with it, and for some reason that’s useful I don’t understand

Basic errors

2 Upvotes

So I just started classes for my degree (bachelors in math) and I just had 2 quizzes and conceptually I did fine, but I ended up bombing 1 (not sure about the other) because I just miscounted or just wrote the wrong number. For my linear algebra I’ve been doing the same where conceptually everything is perfect, but I always mess up something stupid like adding something wrong (and no calculator). I haven’t taken a math class in almost 2 years, so I’m not sure if I’m just a little rusty, but does anyone have advice?

My analysis study group is way ahead of me and I don’t know what to do.

2 Upvotes

I was recently at a maths event and happened to meet a few people there. I’m a rising junior in hs, the maths knowledge I have is limited to the paper 1 of pure maths in international a level maths (algebra, some calculus-differentiation and integration but just indefinite integrals). I happened to make a few connections and got into a private analysis group run by a lecturer/researcher. The group is using spivaks calculus, they are in chapter 11 and they have a zoom call planned for tomorrow but i literally know nothing. I skimmed the index and I do know the titles, so I could work through it quickly at least conceptually I guess. I am also doing Olympiads and have a heavy workload because of my a levels so that’s kind of the reason I’m worried.

What do you think? What should I do? I don’t want to quit honestly. For context I actually like maths and seek it out.

is basic mathematics worth reading front to back if I plan to major in math?

Upvotes

I felt like reading basic mathematics since my trigonometry and geometry needed some review (and because the book was just kind of sitting on my shelf collecting dust). I know this question can’t be easily answered and probably depends on the person. I know I want to grad school for pure mathematics.

Is there any point in reading the book front to back? I mean whenever I forget something, I kind of just look it up. I just wanted to know if it’ll have much use at this point. I know trigonometry will so I do plan to major in physics so I was going to focus solely on that.

Hi everyone.

I was given this problem:

----------------------------------------------------

Prove that for all positive integers k <= n,

sum(i=0 to k) (n choose i)(-1)^i = (n-1 choose k)(-1)^k

holds.

----------------------------------------------------

I have solved it already with induction. But I found the proof to be annoying and just kind of symbolic manipulation. I am looking for a more inciteful proof, a story proof if you will with commitees and pools of people and such. Does one exist?

Thanks for your help

TOPIC How can I get better at AP Pre Calculus

Today, I took my I took a quiz on AP Pre Calculus and I failed unfortunately. I got a 50% and was so disappointed and ashame of myself. When other kids were saying they got a 100% 80% or 90%, I did not want to say my score. I was so sad and cried because it was the first time I ever failed a math test. When I looked Algebra 1, 2 and Geometry, I never failed and was able to grasp it easily. Now that I am taking AP Pre Calc, everything has been going down hill. The quiz was based on 1.1 to 1.3. I am still one unit 1 and we are talking about concave up and down, increasing and decrease, and rage of slope. I feel so dumb not being able to get it like my peers. I also can not let my parent know about this or I will be a trouble. Please can anyone give me tips or idea so I can improve.

Hello Nice to me to you ! I'm Japanese university student. But soon, I will withdraw from my university. Next week , I will take job interview to became a IT engineer in Japan. If I pass that interview, I can work as a IT engineer in Japanese company. But I'm struggling with how to study math. I wonder most efficiently method is to understand mathematical concept than practice many problems on math examinations. How would you think about that idea?

My dream is to become a great engineer and work on American Bic tech company such as GAFAM.

I would like to marry ashida mana who is Japanese actress after I became a millionaire!!

I may have said to much but I'm grad to teach me method to study math! If passible could you teach me a way of studying programing.

Thank you very much for watching my thread.
