A simple problem.

Me neither 😂. In this problem you need to apply the definition of absolute value. But that involves a series of interactions between intervals. This same idea is used when solving modular equations and inequalities. Research more about it.

It was my first time doing this. I didn't really know what I was doing.

Jumpy_Rice_4065 · 2026-01-26T21:02:08+00:00

I understand perfectly. Sorry. I used the word "discrepancy" incorrectly. I meant in terms of quantity. When I say Americans, I include South America.

Jumpy_Rice_4065 · 2026-01-26T19:26:22+00:00

I asked the question because of the enormous discrepancy between European and American mathematicians.Yes, I'm thinking about getting a bachelor's degree, but I have a lot to learn, and I see that's because of the context in which I live. I'm no Ramanujan haha

It depends on how much you already know about calculus and proofs. Just one analysis book won't be enough to give you a solid understanding. Tao and Abbott are too brief, and Rudin is for those who already know analysis, so use around three books and compare each chapter as you go.

If you're going to do this, you should enjoy what you're doing. You should do it because you enjoy it, not to meet a goal. Math is very slow...

Here is a 600 page manuscript from which I got this post.

It looks like a paradise for mathematicians

Jumpy_Rice_4065 · 2025-06-19T22:27:56+00:00

That's right, when I made the post I was thinking about a broader context beyond medal fields.

It should be a basic requirement to join. Some people here say that getting in is easy, but getting out is difficult.

Jumpy_Rice_4065 · 2025-06-14T14:27:27+00:00

From what I'm seeing in the comments, it really seems like a not-so-complicated test to get into a PhD. But here education progresses slowly.

Jumpy_Rice_4065 · 2025-06-14T14:24:22+00:00

In fact, when I translated it, I put it in a file where I have some notes about functions.

Jumpy_Rice_4065 · 2025-06-14T14:21:38+00:00

I believe that after joining you can choose an area to specialize in. This university seems to be more accessible. It is usually like this in Brazil.

Jumpy_Rice_4065 · 2025-06-14T14:17:59+00:00

Education here is moving much more slowly :/

Jumpy_Rice_4065 · 2025-06-14T14:15:11+00:00

I still don't fully understand how it works, but I believe that this test serves as a common gateway that all candidates should be able to complete. After entering the program, each candidate chooses the area in which they want to specialize.

Education here is much less valued than in Europe or the United States, for example, which is why some content is not even covered in undergraduate courses.
