Havent taken a math class in 10 years, need college algebra, calculus, and discrete math, where should i start?

Hey all, just decided to go back to school a few months ago and have completed all my other gen ed courses. Been waiting to do kath so i could do them all in rapid succession.

Havent taken math since high school algebra about 10 years ago. I have always liked math and been quick to pick it up just dont remember much from back then.

My goal is to test out of college algebra (CLEP) by the end of june then take calculus and discrete math through study.com

I defintiely need a refresher on the algebra basics and am planning on using khan academy.

I am also working through the logic and fundamentals of mathematics on brilliant.org and will probably continue through some of the algebra courses on there as well.

Would you reccomend doing anything else? Thanks in advance.

Good books to brush up on Algebra, Geometry and maybe some Calc?

Hi,

I have been self learning C++ and JS for a while now (weird duo, I know). After trying to follow a Game Engine series, I feel I'm lacking/forgotten some fundamental concepts in math. Has anyone had this issue and found a nice series of books that helped them satisfy their needs?

I suppose I could also follow an online series too if anybody has any suggestions along those lines.

Thank you.

Edit: Thank you everyone for your amazing suggestions.

Economics expressed in Mathematical language? Set theory, calculus, algebra, statistics, Operations Research... what tools do I need to express economics rigorously?

I have a STEM background, math-heavy. I now have to study Economics very quickly, both Micro and Macro. It's written in plan language, and, at first blush, the assumptions of Neoclassical theory seem weird - people don't have explicit and consistent utility functions that can map any basket of commodities to a single numerical Real value, or even ones that can consistently organize the sets of possible baskets by preference or indifference.

However, these formulations started to make sense to me once I tried to phrase them as mathematical statements - I'm getting the impression that they're an effort to take a very complicated and messy reality and express it into tidy, mathematically rigorous models. You don't really answer the question you set out to, but you answer one about something that's somehow close to your target while being much easier to measure and model and operate with.. It's the resource-allocation equivalent of physics' infamous "perfect rigid sphere through a frictionless void on a perfectly straight inclined plane with infinite friction coefficient and no slip or rolling resistance being released at time t=o with velocity v=0" as something that is utterly deranged and surreal at first glance, but is a useful first approximation on the long road to "how should I build the brakes on this car so it can go down the steepest hills with roads on them at a fluid yet safe traffic speed" or "how do I design the rails and wheels on these drawers so that they slide down into place when released and slow down smoothly at the end so that they close just so".

Sorry for the detour. TLDR, what I mean to ask is: what are good textbooks on "economics for STEM-trained dummies" or "economics in math-speak" or "good luck writing any of this digitally without generous helpings of AMS-LaTeX"?

In Defense of Algebra

Lately, I've been growing concerned about the increasing influence of the argument that advanced high school math classes are somehow unnecessary or not worth putting students through. While I do think there are a lot of things that can be improved about the current state of U.S. math education, I feel an urge to defend a subject that I love and think is essential learning for all students. I've summarized my best arguments for advanced high school math education below:

1. Math is beautiful: writing a proof is a meditative experience that can make you feel closer to the universe and improve your abstract reasoning ability. Replacing this with something more "practical" like a class on paying taxes would be like replacing literature with a car owner's manual.
2. Math is hard: out of all high school subjects, math is probably the hardest to master without feedback from an instructor and peers. We should be giving students more structure rather than less.
3. Math is useful: Math is a really powerful way to describe the world. Because of this, many of the highest-paying jobs in tech and finance rely heavily on advanced math. If we discontinue advanced math education (even voluntarily on the part of students) for populations at schools in low-income neighborhoods, we make it harder to identify the students with the talent for these positions and stifle social mobility.
4. Mathematicians make good citizens: We live in an increasingly complex world, where policy-makers rely more and more heavily on statistics and mathematical models. Mathematical understanding is key to helping the citizens of tomorrow cast more informed votes.

If math education is so bad, is there anything we can do to fix it? I'm less sure about this, but I've included two proposals below:

1. Let kids write proofs! Why we keep students so far away from what mathematicians actually do is beyond me. This is the fun stuff, let's get them engaged. Bonus: longer retention of information and more self-contained classes, decreasing impact of disruptions like a pandemic.
2. Have students read arguments that use applied math. Reading science and econ papers that use statistics and other applied math techniques (especially ones that get things wrong) will help students evaluate mathematical arguments in the real world. Bonus: they will also get a better sense of what non-mathematicians actually use math for.

I've included a longer form of this argument in a [substack post](h

Would it be recommended that I take Linear Algebra during my senior year?

Context: So, I finished with all the math classes that my high school offers (up to AP Calc BC and AP Stats) and I feel the need to take math for all four years in high school, as an aspiring engineering major. Is Linear Algebra a good choice amidst the chaos that comes with applying to college?

Also, in the case of me not taking this course (or any math course), would colleges dislike seeing only three years of math in my transcript?

Thank you

As an engineer/applied-scientist, is learning abstract algebra beneficial?

Hello, Iβm a PhD student studying Molecular Engineering, and my BS and MS degrees are also in the physical sciences and engineering. For context, most of my research work involves programming and numerical analysis, mostly for the purpose of performing physics simulations or applying machine learning tools. Needless to say, my day-to-day work is heavily focused on performing *applied* mathematics.

I love math -- it's why I chose this career path, but for a while now, Iβve felt a desire to dive deeper into the rigor of pure math topics that I haven't had an opportunity to learn yet. However, I've been having some trouble deciding which classes to take (as I choose my final elective classes needed for my degree), as it's hard to tell which ones will most benefit my way of thinking about abstract topics and phenomena. I've been considering taking classes in abstract algebra, or real analysis, or topology. In general, I'm a self-study type of person, so I've been trying to learn some of these topics on my own, but I feel that in this specific context my efforts would be much more fruitful with the assistance of a class (for instance, I have been trying to study Abstract Algebra by Dummit and Foote on my own, but I feel like my progress is very slow, and I'm missing the point with respect to many central themes).

So, what are your thoughts? If you could recommend some pure math classes that would most expand the mind of someone in the mathematical sciences, what would you recommend? Do I just hold abstract algebra on a pedestal, and would my time be better spent in a different pure-math class?

Any feedback would be much appreciated, and thank you!

[Q] Resources for Multivariable Calculus and Linear Algebra

Iβll be starting my Master in Statistics this Fall and an understanding of Multivariable Calculus and Matrix Algebra are a crux to many of my first semester courses. Although I have a background in Mathematics and have studied Linear Algebra and Differential Calculus in my undergrad which was approximately two years back. I am looking for a MOOC or quick course that will help me with enough material walkthrough that would be required to grasp the Statistical concepts. The reason Iβm asking for an online resource and not a textbook is because I have a full-time job right now and going through an entire textbook that is not an easy read would be arduous.

Thank you for the help!

Are there Real Life Applications of the Discriminant? (Algebra β Quadratics)

I'm trying to improve as a teacher by relating the mathematical concepts we learn to real life, and I can't for the life of me figure when anyone would ever need to find the discriminant. Does it have any practical use at all? Or is it an observation for observation's sake?

The closest I've found is that it's a "double check" for the number of solutions you end up getting, but the discriminant is the longest and most complex part of the quadratic formula. It seems ridiculous to, at that point, not just compute the rest of the formula, which is almost trivial. In short, if you're going to calculate the discriminant, why not just use the quadratic formula entirely?

Thanks in advance.

Any good books for self-studying numerical linear algebra?

I've taken the equivalent of one or two courses in linear algebra. I also have somewhat of a computer science background. But I've never taken a formal analysis class which might be a dealbreaker (?). Not really sure if I'm jumping the gun here but numerical linear algebra seems interesting.

If possible, I'd like to find a book that gives a good birds-eye view of various common types of problems that arise in numerical linear algebra, the algorithms/methods used to solve them and the intuition/proof for why they work.

Any recommendations/advice?

I tried to use Linear Algebra to reverse-engineer the PHB races to create a modular invocation-like custom lineage system. It didn't work.

I broke down every race into each of its traits (i.e. "Darkvision 60ft", "+1 Language", "Halfling Lucky") and then listed every trait, assigning it a variable name (i.e "X", "Y", "Z"). I turned all of them into equations (for example, Half-Elves are also known as " 1T + 1D + 1Q + 1F + 2E = 1"). I then attempted to use substitution and elimination methods to isolate every variable and assign numerical values to create a point-buy system.

The result was crazy, to say the least. A wizard cantrip of your choice ended up being worth the same amount as a tool proficiency of your choice. I expected some negative values (such as walking speed -5 from dwarves and halflings, or sunlight sensitivity from Drow, as these are both strictly negative traits), but I did not expect Wood Elf's +5 walking speed to be one of them (with a magnitude worth 2 skill proficiencies).
