Hi, my name is Athos. I'm a math teacher from Brazil, and I'm looking for students who need help with math.

My English is still a work in progress, and I'd like to improve it through conversation.

I'm thinking of a language exchange: you help me practice English, and I help you with math.

If you're interested, feel free to message me!

I’m 20 years old (fem) and I can’t understand basic math. I don’t know, in huh school I had a 3.7 GPA and I was a very good student but I always sucked at math, either I’m stupid or lazy because I re read a problem or equation and I don’t know why to do, or I just blank completely.

Thank god that SAT scores were optional because my math scores were so bad, now I’m in college. I’ve been pretty much flunking in college to the point where I’m at risk for academic dismissal. It’s basic algebra and I can’t even concentrate. In lectures I understand it but when I get home I feel like I just can’t get it.ive studied in my own, even went to tutoring but I’ve never felt improvement. I have a test this Thursday and right now I’m freaking out because I do not want to start out my semester horrible. Any suggestions? I’m literally desperate for any tips on what to do or how to study.

I know the procedure of Euclidean Algorithm, I can follow that procedure, I can answer. But I don't know how does that works.

If two circles are orthogonal, then prove that the polar of point P on the first circle with respect to the second circle passes through the point Q, which is the other end of diameter through P. Also prove that locus of a point, which moves such that its polars with respect to S1=0, S2=0, and S3=0 are concurrent, is a circle which is orthogonal to all the three circles.

I am not able to understand what exactly I even have to prove. Even the equations of the circles are not given. From what I understood, I think for the first part both circles are intersecting, P and Q lie on the first circle and are end points of the diameter of that circle.

I have been on this assignment for like 1 hour and I still cant get it right... I have used almost any ai known to man... Can you guys get it?

hi! this is going to seem ridiculously easy of a calculation to some people here but i have dyscalculia and i dont feel confident that the answer i got was correct. this is pretty important because its for the enclosure of a new pet so i was to be super sure that ive got this right. the dimensions of my enclosure are in the picture id just really like if someone could calculate the cubic feet of this so i can compare to my answer
thank you!!

It’s embarrassing Ik but idk how to factorise the teacher won’t explain it and my maths book isn’t explaining it either

Bonjour,

J’aurais besoin de conseils. Je suis étudiant à l’Université Clermont Auvergne et je viens de valider ma L1 sur le portail Math-Info. J’ai eu une moyenne générale de 14,37, avec 13 en maths au S1 et 11 au S2. Même si je ne me considère pas particulièrement fort en maths, j’ai été admis en double licence Math-Info.

J’aime vraiment les maths et l’informatique, j’ai envie d’apprendre et je suis sérieux dans mes études. Mais je trouve parfois les maths très difficiles. En L1, j’ai surtout réussi parce que je mémorisais beaucoup de formules. Comme les examens portaient majoritairement sur du calcul, j’arrivais à appliquer ce que j’avais appris.

Par contre, en L2, je vois bien que cette méthode ne suffira plus. Il y a beaucoup plus d’abstraction, et j’ai l’impression d’être un peu perdu parce que je ne comprends pas toujours vraiment les notions. Je m’appuie aussi trop souvent sur Perplexity ou ChatGPT pour avoir des résumés des parties difficiles.

Ce que j’aimerais, c’est développer une vraie compréhension : savoir quand utiliser une formule, pourquoi elle s’applique, quand il faut éviter une méthode, et avoir les idées plus connectées entre elles plutôt que seulement retenir des recettes.

En informatique, je suis plutôt à l’aise : j’ai eu 19 de moyenne en programmation et 12 en algorithmique. Est-ce que vous auriez des conseils concrets pour mieux travailler les maths, organiser mon temps et mes révisions, ou des livres solides à recommander pour prendre de bonnes bases et progresser ?

Je n’ai pas fait le lycée en France : j’ai terminé mes études en Italie il y a cinq ans, puis j’ai travaillé avant de reprendre les études en 2025. Du coup, j’ai parfois l’impression d’être en retard par rapport à certains camarades qui sortent tout juste du lycée et ont encore les notions fraîches.

Je sais que la réponse la plus évidente est sûrement : « travaille régulièrement, sois discipliné et fais des exercices ». Je suis d’accord, mais j’aimerais surtout des conseils concrets sur la méthode. Comment vous organisez vos révisions ? À quel moment vous relisez le cours, vous refaites les démonstrations ou vous faites des exercices ? Comment vous espacez les révisions et décidez de ce qu’il faut travailler en priorité ?

Merci d’avance pour vos conseils !

Can anyone here please take a look at some of the claims made by Ali Fazely on the supposed mathematical miracles linked to the number 19 of the Quran, especially using prime and composite numbers? I genuinely don't even know what to think at this point

For example (and this is both used as evidence for the removal of Quran 9:128-129 as well as trying to demonstrate the nature of the supposed divine code of the number 19 in this book):

The number of verses in the Quran from 1:1 until 19:98 (since it's part of the whole code 19 stuff) is 2346 (not including 9:128-129). The factors of 2346 are 23x2x3x17 which have the prime indices of 9127 similar to Quran 9:127 being the cutoff point as proposed by Rashad Khalifa (the person who developed this whole idea of the Quran being shaped around this number 19 in the first place). Finally if you place the digits 2346 in a permutation table, the 19th permutation is 6234, the total number of verses in the quran if you remove 9:128-129.

I don't understand how this is happening, since it's one thing if he only used this method once selectively, but he continues to use it similarly over and over. Wanting to understand whether or not there is more to this, or it's simply pattern recongition and being able to use many numbers at hand.

If someone could take some time out of their day to analyze some of the claims being made and techniques being used, it would truly mean the world to me. This stuff has been stressing me out and I'd like someone who can objectively and non-biasedly look at the following and help me out with it.

So, the actual answer to this particular question is Option B, but when I solved it step by step, I ended up getting Option D.

Could you guys please tell me where I’m making a mistake? This is a question based on general solutions in trigonometry.

Hello,

I'm about to enter my second year of my Chemistry degree and I have a further physical chemistry module that builds on what I learnt last year. I really struggled to keep up with the maths having not done the a level.

Most of what I need to know is a level maths and some further maths topics.

I was wondering if anyone had any advice on effective learning techniques?? (my teacher was terrible I swear to god)

I just rly don't want to fall behind lol

I swear ive done this before but its been so long since ive actually done any maths.

HII so I’m in geometry and more learning probability, but I don’t really understand it. Can I have some tips on understanding it?

I got one of the x right but not the other one which is 5,

The origin problem was 3x^2+7x-20 <(or equal to) 0

I can understand multiplying by x-1 by how is he able to multiply by (x-1)/(x-1)

hi do u guys have some mcq guessing methods that actually works? in both math and theories.

Im a university fresher and studying business. Maths is compulsory for my course. I have not studied maths for the last 6-7 years. (Last studied it in grade 6) I do not remember shit. We have mid term exam in 3 weeks and my course included the following:

Number System
Factors Factorials
HCF LCM
Indices
Logarithms
Exponents
Coordinate Geometry
Linear Equations
Quadratic Equations
Set Theory
AP (might not come for midterms)
GP (might not come for midterms)

I initially thought that things like HCF and LCM would at least be easy but the sums are completely different. There are no direct questions at all and everything is hella confusing. The professor cannot help a special case like me since most of the students had maths at least till grade 10, or even 12. Please guide me on what/how to study since I have no clue how to proceed 😭😭
