This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I live in America... I assume you mean math education. I'll answer from a positive rather than a normative perspective. As a student in high school, since I was young we were taught to do math by formulas rather than understand math with concepts. Most lessons would introduce a concept very briefly, and then get on to how to solve problems that use that concept. And, as you might guess, most people would only care about the how than the why, which did not set them up well for when math became a bit more abstract, as these topics required a strong understanding of previously learned topics. So many students do not have a good foundation in math, which is why I believe many students find math to be so difficult or confusing. (Of course, it is possible to transcend this.)
Till this day, I felt I lived in a very bad & let's just say 'unlucky' area,where all such things prevailed. But I am really shocked to see the case is the same everywhere... I think this is because people here,who really know mathematics, scarce feel like teaching or students lack proper resources,proper technique of learning,conception etc. In this juncture let's just thank Calvin Lin & the Brilliant.org team for this brilliant effort free of cost. I must say 92% of the maths I know today is due to brilliant.org & the same has driven to the treasures Maths has to serve.
I live in India..Here we are taught to get good grades rather than getting good knowledge..(which sometimes may even lead to better knowledge)..I think that getting into IIT is far more tougher than getting into any other university which ranks in top 100.(As told to me)....
Thanks for your replies.
No that might be your place I from Rajasthan, India we are first taught to understand the topic not for grades , getting into iit not the thing which can be done easily by just school grades you should see indian positive place eg kota raj. , isi west bengal, sri chatenya
I thing indian not so good as usa or other but its an average
I live in the UK. In mathematics, I'm told that 40 years ago we spent primary school learning Geometry, bisecting angles and proving a line has 180 degrees etc. Now that's been almost completely removed. At A-level (age 17-18), maths is modular. The exams have between 7-11 questions depending on module and they are highly repetitive between years. Some teachers would try to derive the result but many just skip the derivation to solve problems using the result. The problems in class are often harder than those on the exam.
All calculations are metric. All A-level modules except one use a calculator, so your mental-maths is quite rusty at the end. It is very possible to get 100% in these modules, unlike older papers.
I am told that the UK education system is one of the best in the world, I'm not so sure.
I live in India (Central region) , though I have most things common with otter replies . I am a 10th Grader .
I must say that there are many faults in the education system . We are just introduced with Trigonometry , Quadratics in Grade 10 . We are taught quite much about Polynomials like Vieta's Formula ( which we call the relation between roots and coefficients). Even our school teachers demotivate us from giving RMO . They say that It's very tough to clear even the first level as it is * much harder * than IITJEE . They say even 12th graders couldn't clear it. (nonsense - I say )
Its all because of the coaching , [ I go to (FIITJEE) ] where they taught me logarithm , modulo arithmetic , componendo et dividendo , Calculus , Trigonometry , Quadratic equations etc. in depth
Thus I'm completely dependent by studying on my own ( Topics like Matrices ) and with the help of brilliant community (also my coaching) .
Thank you all those who read this and even those who shared there views in this discussion , we all came to know so much about each other , and nonetheless we are truly a family .
In Brazil, education is in pretty bad shape. That is, mostly, for cultural reasons. Education and knowledge are underrated. People just want to finish school, to have the pass degree, not to acquire inteligence and knowledge. Cheating on exams goes large and broad, even in college.
The results are a largely corrupt and unlearned society.
In the engineering college I attend to, there are classmates who find it difficult to understand that a^ -1 = 1/a; for example.
Understanding of a subject is not a must to have the degree. To truly learn you must either study in the better schools (which are expensive for most the population) or study on your own ever beyond what they teach you.

Saying "Grade" everytime doesn't seem much Indian. In India, we call it 10th class.

I wrote that for generality . Class may mean something else to others .
