I had a similar experience where math went from being easy and fun to an intimidating and painful slog. My problem was just how focused most courses are on learning techniques for solving problems. I found all those endless substitutions that you learn in calculus to be infinitely dull and so it was difficult to do a good job. Ditto for the solution techniques for differential equations. Don’t get me started on matrix inverting. I think I had to do a 5x5 matrix once for a homework assignment. What a colossal waste of time.
Proof-based math classes came like a revelation to me. When I took Real Analysis, for the first time in over a decade, math was fun. You weren’t just memorizing and reapplying recipes. You were seriously thinking about unique problems and devising solutions. And all the while, you were learning where all these techniques actually came from and how everything connected together.
I don’t understand why we can’t have more proof heavy math in high school. Who cares whether you remember the arctan substitution or whatever in an integral; I’d always just use a solver for that anyway. I’d rather be learning about what an integral is in the first place.
I'm a private tutor who works with adults on proof-based math. I've often had a similar thought to the one you're expressing here --- I also found proofs pretty revelatory when I first exposed to them and wondered where this magical tool had been all my life --- but I wonder how well this experience would scale to the mass of students in high school math classes.
After teaching proof-writing to my students for several years now, I've seen a lot of variation in how quickly students take to the skill. Some of them have the same experience that it sounds like you and I had, where it "clicks" right away, some of them struggle for a while to figure out what the whole enterprise is even about, and everything in between. Basically everyone gets better at it over time, but for some that can mean spending a decent amount of time feeling kind of lost and frustrated.
And this is a very self-selected group of students: they're all grown-ups who decided to spend their money and spare time learning this stuff in addition to their jobs! For the kind of high school student who just doesn't really think of themselves as a "math person", who isn't already intrinsically motivated by the joy of discovering what makes integrals tick, I think it would be an even harder sell. High school math teachers have a hard job: they have to try to reach students at a pretty wide range of interest and ability levels, and sadly that often leads to a sort of lowest-common-denominator curriculum that doesn't involve a lot of risk-taking.
A more rigourous approach was tried after WW2, when Americans feared the Soviets were edging ahead mathematically/scientifically. It was called "New Math" [0]. For an example of the type of textbook high school students were taught from, check out Dolciani's Modern Introductory Analysis (the 1960s and 1970s editions only; the later editions were dumbed down, especially when Dolciani died) [1], which starts with set theory, logic, field axioms, and proof writing techniques.
> I don’t understand why we can’t have more proof heavy math in high school.
proof based math requires critical thinking and its a lot harder to scale the teaching of critical thinking. We dont' pay enough for teachers of quality to be able to do this at the public school level. Its also much harder to test for in standardized tests.
Great post! It's always interesting to see the experiences of fellow peers going through Math Academy.
It took myself 2 1/2 months to complete Mathematics for Machine Learning on Math Academy last year (2024) working through reading material, taking notes, and completing all the exercises took all day everyday I loved it, this was after I completed Khan Academy (starting from the beginning of mathematics negative numbers, to the end differential equations) because I kept putting it off for years when I got to busy.
The main thing for me was learning not to get too frustrated when getting an answer wrong. If I made a mistake, I focused on understanding what went wrong, looking up youtube videos on the topic if it was confusing, and then trying again.
At the end of a lesson I wish I had someone to bounce questions off of but thats when I used chatGPT.
I really want to do Math Academy and even briefly tried it a year ago. It's absolutely great but it's also very expensive. I know that math skills are invaluable, it's far cheaper than schooling, and that long term the investment is likely to pay for itself but when you're skint $49/month is still a pretty hefty sum, especially if you live outside of America. For context in the UK, a basic gym membership (£17/month) and a SIM only phone plan with unlimited data (£22/month on a two year contract) only costs £1 more in total than Math Academy (£38/month). I can't help but feel that the people who would benefit from it the most are also the people least likely to be able to afford it.
Go on eBay and buy the following Open University book sets. They go for around £30-50 a pop: MU123 (basics), MST124 (more complex). 6 months worth of study in each book set. If you like it do MST125 (even more complex) and M140 (stats) after. That's the first year of a mathematics degree literally from the ground up through GCSE and A-level stuff. If you really like it, get a student loan and do the associated accredited degree.
£30 for 6 months is pretty damn cheap and you get to keep it forever!
This is a proper accredited course developed over 50 years or so with its own textbooks and material from a respectable university, not a gamified subscription portal experiment put together by god knows who that can disappear in a puff of smoke at no notice.
The way I come to look on such offers (monthly unlimited subscriptions) is not the net price itself, and not future supposed returns to it (who knows what they be, and they for sure will depend on many other things), but how many hours a week I am willing to spend on that service.
If you can and willing dedicate on average 2 hours a day (a big commitment but I think I was able to hold it for several month with them) the cost of mastering, say, Linear Algebra will be ~4 less then if you subscribe and will be spending ~30 minutes a day.
I guess it depends on where you are at in the world, but in our neck of the woods $50/month is an absolute bargain compared to using a tutor. Not to mention you get to work at your own pace and to practice spaced repetition consistently.
It is. But I don't think there is an alternative way to make it sustainable. There are just not that many people who are serious about self-education, and you won't like it to cater to the less dedicated customers.
> I can't help but feel that the people who would benefit from it the most are also the people least likely to be able to afford it.
Even if it were $10/mo, the people who would benefit from it the most (around the world) still can't afford it.
my read as a US person is that math academy is optimized towards students who would otherwise be well served by an in-person supplemental math program. at the earlier grades for math academy (grades 4-5 etc) the main competition i've encountered are in person programs like AoPS, Russian Math, or Kumon. The prices for those range between $450-$100/mo and for a student or student and parent combo that may be looking to supplement their math classes or for somebody who needs to home school for a period of time, mathacademy at $50/mo is a steal.
I wonder if they could charge lower rates for people who live in poorer parts of the world.
$49/month is almost nothing to me now, but it would be prohibitively expensive for a 15 y.o. me in freshly independent Czechia.
I suspect it would also be prohibitively expensive for most 15 y.o.s in the developing world today, and these are the guys and gals who stand to gain the most.
I'll call out 3b1b and khan academy for me. Especially over covid. Made math fun again.
My middleschool principal thought it'd be a good idea to skip me over pre-algebra into alg 1.
Turns out that doesn't work great, and I still have confidence issues because I have a hard time remembering the properties of addition & multiplication by name. I know the rules.
A noun that only refers to one thing isn't a real word, so if you want to cure yourself of "the associative property" being meaningless, you could study other algebras where the rules are different.
My middleschool principal thought it'd be a good idea to skip me over pre-algebra into alg 1.
Next time you read a novel, try this:
1. Read each sentence at half your normal reading pace
2. Skip every other chapter.
Sounds ridiculous, right?
That's my reaction when people propose grade skipping as the only solution for a child whose natural pace is 2x the 'standard' pace at which math is taught in school.
Over the past few years, while homeschooling my daughters, I've come to see the way math is usually taught as horribly pathological. In the US, where we live now, it's often seen as a competitive activity -- almost like a sport. In the UK, where I grew up, that wasn't the case but still it was taught as this huge body of knowledge and skills with almost no motivation.
My daughters are so advanced in math and I really don't believe it's even mostly due to innate ability. It's because, just to take an easy random example, when we studied geometry our very first lesson was me pointing out that the word "geometry" just means "earth measuring", and it was useful for farmers to be able to do that. Or, when we proved the irrationally of sqrt(2), of course I entertained them with the tale of Hippasus being thrown into the sea by the Pythagoreans. For basically everything we've learned there are so many fun stories. It makes me sad that most students of math never get to hear them.
As a b and c grade student, who messed about, stumbled through a not very good info technology degree at university I definitely agree with this. The stories and lore are what makes me now so interested in programming and software engineering. I've pretty much taught myself everything programming related and that's what I work as too. I desperately want to learn math up to and including calculus as I feel like it's a hidden shame that I'm a programmer with not much math ability. I'm actually considering signing up for math academy.
I am currently studying for our country's version of the SAT and, having tried Math Academy — having been convinced there is nothing anywhere as polished and developed on the market — I still had to cancel my subscription after the first month. The price just wasn't worth it; over a single year, it translates to a cost greater than one-on-one tutoring.
Small companies have to understand the value of local pricing — nobody is willing to pay above h percent of their salary for a service X, and there's only so much that rule can be bent. I understand that, at the end of the day, the company still has all their expenses in USA prices, but for digital services with no manufacturing or logistic costs, it can be better to make a modest profit than none at all.
Wow that’s a pretty glowing review of the service. Sucks about the pricing though.
I haven’t really looked at math academy, but I was in school (including college) I probably learned 40% of math from khan academy, 40% from textbooks, and maybe 10% from lectures.
Always great to hear from people on the far side of the valley of despair. I don't think it is pointed out enough that people who fall off of "mount stupidity" can sometimes get really really stuck. In my experience when they do that at work it is quite traumatic.
Another good book for the author and others is "5 Elements of Effective Thinking" by Burger & Starbird. It thinks about thinking which can sometimes side step the depression of suddenly not thinking you know anything about anything that accompanies that big drop off mount stupid.
Math Academy is awesome, I'm fully hooked, but, repeating something I wrote elsewhere: it is a bleak existential confrontation with your ineptitude with fractions.
I’m doing math academy and I have two comments. First, the value of this site comes from its content which is very thorough. I think it’s a great way to learn math.
Second - I love the website. It reminds me of what I think of as the golden age of web design where sites were mostly server side rendered with a little jquery / Ajax sprinkled in, and more information density was preferred.
I have enjoyed the challenge of relearning mathematics with Math Academy as well. I find the format and reviews extremely helpful- it is so refreshing to end a lesson or review early if you are getting all the answers right compared to the drudgery of my schooling experience where you are getting question after question that isn't introducing a new mental challenge.
My only desire is that their site worked on my phone- it would be nice to do a lesson when I have some free time and some paper.
I read this article because I wanted to learn more about their Math Academy experience, but I found the preamble and backstory a little long, which caused me to skim.
Re: Math Academy, I used the service for ~3 weeks last year from a post here on HN by the guy responsible for the AI/ML knowledge graph behind the platform (I believe his first name is Justin). I was "only" doing about 30-60 minutes a day (a little bit higher than their guidance, but low for someone not doing math otherwise IMO).
N.B. Due to substandard early instruction combined with being "gifted and talented", I was placed by the test into Math Foundations 1 (or 2?). For example, I still don't have an active/working mastery of the unit circle. So if you're a real whiz, YMMV.
I found Math Academy effective at showing me my weaknesses and sharpening those skills in the short term, but I probably didn't do it for long enough to benefit from the spaced repetition effects. I found the UI/UX better than Khan Academy (sans AI), and much less tedious (when I demonstrated understanding, the questions moved on or increased the complexity vs. doing the full problem set no matter what).
When I cancelled within the first month to receive my refund (see other commenters mentioning the high price), I was surprised to see my support email and refund request email both went to one of the founders (or owner?), Sandy Roberts, who was emailing me while also attending her daughter's college orientation (or helping her move, can't recall right now).
Cancelling was painless once I realized I was getting a response from someone at the platform --- so if you're interested in trying it, I can recommend giving it a shot. Maybe there's some sort of economy for them if more (adult) people sign up, because 50 USD still feels a bit steep.
I understand that everybody has different financial circumstances, but personally I find it so odd how people prioritize their spending. $50/mo to level up your math game? Too much. 8x $6 lattes per month - totally worth it. $200k+ for a university education after which you STILL won't know basic math (or much else useful for most majors) - super totally worth it.
For me I'm just willing to pay a lot more than other folks are to learn interesting skills. Math, sailing, music, leatherworking, perfume making, whatever - to me that's such a good use of money.
As an aside, all Dunning and Krueger showed is that everybody thinks they're in the top 1/3 to 1/4. (At least everybody in undergrad school at Cornell.)
Math Academy and a SQLite course pulled me out of despair as well. I grew up thinking I was relatively smart and being able to learn on my own, but only randomly and sporadically. After not learning much the past few years and feeling very stupid, I decided to look for some paid courses to take on Hacker News.
The SQLite course was in a very different video format and took roughly 20 hours, but I learned a lot and immediately used that knowledge in two software projects that would've seemed insurmountable to me.
As for MA, it's taken a lot longer and has been difficult. I'm now at 6000XP and halfway through Fundamentals II. I have a lot of thoughts, but I (kind of) plan to (probably not) write a review after having completed Foundations I-III, since I haven't talked to anyone else who's done so so far.
I started reading the article without paying much attention to the word Academy in the title, and was attracted by the single word 'Math'. In the first part, I found it interesting when the OP talked about their learning experience. In the final part, my interest faded when their writing turned towards a business entity.
I am going through Math Academy and I like it very much. I have done advanced technical work in my field but my math background had weaknesses from my public schooling in a large urban area and some experimental math instruction in high school. The ability to do it over is oddly exhilarating.
From listening to interviews, it seems like after completing a full undergrad's worth of math courses, they plan to expand to CS and math-adjacent fields (probably physics at least?).
I’ve used Khan Academy with the kid and always been impressed, but Math Academy sounds very promising indeed. Anyone have an informed view on the relative merits? I don’t mind paying the monthly fee if there’s genuine value.
I tried math academy about a year ago since I wanted to finally get a strong grasp on linear algebra.
But I gave up during the diagnostic test. It was very, very long, and didn't seem to be adjusting in difficulty, and asked similar questions. I'm normally a fast test-taker, but after about a third, I figured it would take me an hour and a half or two hours more.
You can do the diagnostic test in multiple sittings: I think I split it up into 3 parts?
To some extent, though, I don't think you're meant to spend lots of time on each question struggling to figure it out as it's trying to determine what bits of the course you can skip, so if you can't answer a question relatively easily it's best to just say "Don't know" and move on so you get some revision during the course.
It's still the same and I agree it's a splash of cold water to sign up for the platform and immediately be put through the gauntlet. I would say it's worth getting through it as none of the actual course material is like that, it's much more bite-sized. But I hope they figure out a way to smooth out that onboarding process, maybe split the test into segments and weave them into the rest of the material somehow.
def try again. I personally absolutely bombed it. But you know its been 20 years since I've been in a math class. Its all to figure out where to start you off. It doesn't matter where that is, it matters where you go from there.
Inspiring and well written. It resonated with me for I find myself in a similar position. I wonder how much time did the author commit on weekly basis. Nonetheless, I wanted to signup on Math Academy immediately but doesn't look cheap.
Are there any other recommended websites for learning math (apart from Khan Academy, Math Academy)?
Hey! This is my blog post thanks for reading! At my peak I spent roughly 4h a day on math academy because I wanted to get 100+ XP. I've brought it down to about 2h a day since I'm also teaching myself python for my goal of being a MLE in the future.

I don’t understand why we can’t have more proof heavy math in high school. Who cares whether you remember the arctan substitution or whatever in an integral; I’d always just use a solver for that anyway. I’d rather be learning about what an integral is in the first place.
