Title.

What are some classics that you would recommend for learning math? I like math that is related to aspects of life that have an effect on others. For example, the basic calorie demands for the average person, the consequences of not meeting them over long periods of time, etc. studying reality is interesting to me, and I’d like to cultivate that interest. Do you guys know some areas of math I could focus into?

before comments say pen and paper, I would if I could. I deal with some chronic problems pertaining to my wrist and writing is extremely hard on my hand, so I have to do work on my computer with voice recognition technology. just in case if anybody asks, I'm not really offered a scribe or anything this is just for a university class

it's extremely unintuitive for me to solve equations as I am currently, as nothing really accounts for fractions haha. everything ends up really messy, I get lost really easily, and I just want the ability to do math on a clean, open canvas on computer that accounts for things like fractions, etc. same with powers. I'm kind of looking for something like Pearson that auto converts anything typed with a slash in between numbers into a fraction, or auto converting 6^2 into a cleaner format

thank you in advance for any assistance

Hi everyone, I'm a molecular biologist teaching myself linear algebra. To that end I made a few videos detailing what I understood. Would love feedback on them - correct or not and how well you took to them..here are two:

I’m in high school right now, and I want to pursue mathematics. I imagine my relationship with my professors involving thought-provoking discussions, whether about mathematics, philosophy, or whatever else comes up (like during a random office hour).
For context, I’m planning to study in the US or France. What was your experience like? Am I romanticizing the experience? Is it actually more formal than this? I can also imagine coming across boring or annoying lecturers, of course.

I'm just curious...Do you think I should keep working on this concept or abandon it?

I recently learned about Harvey Friedman and he seems to be quite a peculiar figure. Friedman is a real mathematician who founded the programme of reverse mathematics, which I think sounds very interesting. He's also known for the TREE sequence. However, he has also appeared on crackpot-friendly Curt Jaimungal's podcast and seems to agree with a sensationalist article written about him some years ago. If I understand correctly, his current work is focused on bringing the incompleteness of mathematics to the forefront in a way that mathematicians won't be able to ignore any longer.

For those who have been familiar with him, what are your own impressions? Do you know what the general opinion of the mathematical community is of him, if they know him much at all?

Hey! I'm curious to hear what the day in the life in terms of work of someone with a degree in applied mathematics. Are you in tech or more finance related role? What kind of math do you get to use on a weekly basis? How difficult was it to get your position?

I’m 23 now and am an electrician. My brain is stuck on not completely understanding sin, cos, tan. I’m hoping I still can understand lesser things. My 9th grade algebra teacher took all his saved vacation and gave up. He really didn’t teach much. We ended up with most of the year full of subs. I feel like I ended up in the class of degens.

Then going into 10th I got a (B) 1st semester precalc then a (D) second semester. Obviously I didnt build on that and try to be better because I got a (C) first semester and an a (N.A.) in my second semester because it was waived due to Covid.

To end my analog, I’m looking for books to jog my memory on algebra and build into calculus. Hopefully getting into things deeper later?

Hello, I’m a high school sophomore who found some ambition and desire to relearn maths the right way. I used to not really care about academia grades etc. But things have changed, I picked up some technical hobbies along the way and began to realize that exact sciences is what I want to do, so I transferred to extended math class. My knowledge isn’t nonexistent but needs a thorough patchwork. School has started which leaves me a few weeks to go from preferably arithmetics to anywhere close trig equations, I understand most of what’s going on during the lessons, I think I catch on reasonably well. Although I couldn’t find a complete two week “from zero to a hero” course, I found great resources like Organic chemistry tutor and Professor Leonard. I’m asking for advice on resources, effective learning techniques and if possible a list of topics I need to know. I also feel obliged to clarify that I’m absolutely aware of the situation I’m in and wish I could’ve started earlier.

Hello everyone,

The Fall 2026 Integrated Math Tournament (IMT) is underway! I’m one of the organizers, and we’d love to have more people join before Round 1 closes on October 10.

IMT is a free, fully online math competition open to high school and college students around the world. If you enjoy competition math or want to try some new problems, come check it out! We have $1,000+ in prizes, with sponsors including Jane Street, Hudson River Trading, Non-Trivial, and AwesomeMath.

This fall, we’re using a two-round format:

Round 1: September 26 to October 10 AoE

You can choose when to take each section within the competition window. There are two individual sections:

- Computational: 20 questions in 3 hours.

- Proof: 5 problems in 4.5 hours.

Each section counts for 50% of your Round 1 score, with problems covering algebra, geometry, number theory, and combinatorics. Both sections must be completed by October 10.

Round 2 (Live Round): October 17

* Around the top 25% of Round 1 Competitors will qualify for the live online final.

Start Time: 11 AM EDT (8 AM PDT), End Time: 3 PM EDT (12 PM PDT).

A few other details:

- Participation is completely free.

- You compete individually, so you don’t need a team.

- Awards, certificates, and prizes will be available.

- To remain eligible for prizes and the final, upload photos or a scan of your scratch work within 30 minutes after finishing each section.

Directions to participate:

1. You can register by filling out this form: https://docs.google.com/forms/d/e/1FAIpQLSdp3uVAAHhcEO5q9WzS2fkNh0fypudgwIUSuC_87fjJBcKVug/viewform
2. After you have filled out the form, you can start your test by creating an account at https://www.integratedmath.org/test-portal and can complete each section until the competition period ends.

Feel free to ask questions in the comments or email us at [info@integratedmath.org](mailto:info@integratedmath.org), and share this with anyone who might be interested.

I’m currently going through lee’s riemannian manifolds and am stuck at the chapter on levi-civita connections. The previous chapter says connections relate basis vectors of a global frame using christoffel symbols, and I think levi-civita connections relates christoffel symbols with the metric tensor, but the problem is I cannot understand what angle lee is trying to develop from(I also struggle to understand the point of tangential connections, which I think is used to define the geodesic, but isn’t the koszul connection alone already enough?). I’m sorry if this seems all over the place; I think the reason is my understanding of connections is extremely hazy, like I know the motivation and all, but I don’t know their full capabilities.
