I’m working my way to a CS degree and am currently slogging my way through an 8-week Trig course. I barely passed College Algebra and have another Algebra and two Calculus classes ahead of me.
How much of this will I need in a programming job? And, more importantly, if I suck at Math, should I just find another career path?
The most advanced math a typical developer needs is Fibonacci, and if you can’t remember it someone will show you a cheat sheet.
I was doing full stack dev for 20 years until very recently. Never needed anything beyond basic algebra EXCEPT for while I was getting my CS degree…had 2 classes, i think, where we were doing matrix math/Fourier transforms, but iirc they were electives…one was writing a very basic 3d graphics driver and the other was working with very simple computer vision…things like recognizing handwritten letters.
Depends on what kind of programmer.
If you’re doing data engineering/science (more of an adjacent field), you need to know linear and probability pretty well to build models, or have data harvested in ways that can be put into vectors.
If you’re doing relational DB stuff (like SQL) set theory helps a lot.
Basic boolean operations in general is also good to know. You don’t need to go too deep in the weeds of boolean math unless you’re also doing a lot of hardware-level stuff.
Any field you go into (not just programming), I would say just basic math for regular financial competency is good to know. Also to analyze your budgeting, your costs, time spent, effort needed, etc.
If you’re a frontend programmer, you only need to understand rectangle width and height lol
Anywhere from very important to not important at all, depending on your specific job.
There is some good news though, you’ve been lied to about sucking at math. Whether by yourself or other people I do not know, but the education research I have seen has been pretty clear that the main difference between people of normal intelligence who are ‘good at math’ and those ‘bad at math’ is how long they’re willing to work on a problem to ensure the correct answer before moving on.
I know ‘try harder’ sucks as an answer but it’s the best one I know of and at least in this case will actually make a difference.
Agreed. Math, for the most part, is very rule oriented and problems only have one answer and often one strategy to get to the answer. If you work on many different problems (in the same subject) you should start to get used to the rules.
Overall I would say a strong math foundation is important to CS but CS isn’t just about coding. You can absolutely get a coding job without strong math skills or even without a degree, it’s just a bit harder to get started. If the discipline still exists you might consider a Business Information Systems degree (we used to call it CS lite). Depending on the position a company might equally consider BIS and CS majors.
i would disagree that math problems only have one strategy for getting to the answer. there are many things, particularly in more abstract math, which can be understood in multiple different ways. the first example that comes to mind is the fundamental theorem of algebra. you can prove it using complex analysis, algebraic topology, or abstract algebra. all the proofs are quite different and rely on deep results from different fields of math.
i think the same thing holds in the less abstract areas of math, it’s just that people are often only taught one strategy for solving a problem and so they believe that’s all there is.
problems only have one answer and often one strategy to get to the answer
Totally disagree
You’re thinking of equations, which only have one answer. There are often many possible ways to solve and tackle problems.
If you’ll permit an analogy, even though there’s “only one way” to use a hammer and nail, the overall problem of joining wood can be solved in a variety of ways.
You’re absolutely right. I was referring to equations which, in my experience, is 90% of undergrad math.
Do you have a link to the research? I’m a math educator and I’d like some good materials for encouraging my students.
Well being able to figure out 1 complex math solution per day vs 1 complex solution per 1.5 days for the person who just has to work on the problem for longer is balloons a lot over the long term.
Like how the average calorie burning difference between people is only 400 per day out of ~2000, but over a month that is like 1.5kg difference of mass burned which is 18kg per year.
But I don’t know if I am interpreting the result you said correctly.
More than math courses - logic courses in general helped me rethink and structure things in a variety of ways in how to approach problems. If nothing else it improves your “if-then-else”-fu to understand when you are not(not(not something))). My math degree required logic courses though at the same time so it made sense. For higher level math logic plays a heavy role and so leveraging that aspect helps in a lot of ways.
Math, despite being a great skill to have, is not mandatory for a large volume of programming roles. It may hurt you in some interviews but interviews are a fucking crap shoot / shit metric either way. Computers do most of the math, so you don’t have to!
Source: I’m dyslexic, suffered from dyscalculia and migraines until I was allowed to use a calculator, and barely passed high school math. No degree. No bootcamp. 8 years as a dev.
I’ve also excelled in multiple roles where colleagues were math or CS PHD’s, and become the senior or go-to on more projects than not. The key part is to know your strengths. I’m never gonna accept a role developing accounting software, or anything that would require me to code complex math on a regular basis. You’d be surprised how far you can get with Google.
The field is incredibly broad. Choose a field or employer or project that’s not doing that an you’re fine.
Being comfortable with algebra is kinda essential, however you probably won’t make much use of calculus unless you go into certain parts of the industry such as game development.
Practice makes perfect though, you may suck at maths today, but there’s nothing stopping you from getting better at it if you work at it
I’ve been a full stack dev for about 11 years. I do some basic algebra but that’s about it.
If you end up working in the medical/insurance field in the USA, you don’t even need basic math! The numbers the programs output are just all made up!
I had the audacity the other day to ask in what order we apply deductibles. (YOU want a deductible applied to something covered at 10%, not 100%. The insurance wants it applied to something covered at a100%) I was told it just picks some at random and hopes for the best, so we use the word “best effort” when it comes to estimating what insurance will pay, since they’ll make that up anyway.
So yeah, just another throwing in that it super matters where you work. At my job we plug in what is industry standard for medical accounting, and say it’s just an estimate on everything else.
I tried to go to University for CS but never quite got the hang of the math part. Instead I got a Certification in Computer Science from an apprenticeship (idk if that’s the right Translation, in German we call it “Fachinformatiker für Anwendungsentwicklung”) within 1.5 years and with extreme ease, because it was way less math-heavy and more focused on actual programming.
I stayed with the company that I did the apprenticeship with and got promoted from Junior to Regular within a year. I work exactly in the field and position I wanted to work in when I was going for the CS degree. In fact, I have the exact same responsibilities and the same pay as my colleagues with CS degrees. It might not be like that in every company, but it did work out for me.
Just for fun, I actually went back to Uni this semester to try and actually finish one or two math modules, but dropped out within 2 weeks because I was hopelessly incapable of even understanding the basic concepts lol
It really depends on the role you are looking for. If working with data and doing analysis, you need some knowledge in stats and probability. If you are working on simulations, you will need basic calculus and algebra. If you are looking at game development, you will need basic trigonometry and vector arithmetic. The one thing you don’t need is mental arithmetic because you have a computer.
That being said, you can get by without these skills, it just becomes harder to see what you need to do, even if you would know how to implement it. This is alleviated if you are working in a team however.
I think folks saying you don’t need math are right. But if you are having trouble with college algebra you might have trouble with CS. Or the teacher is bad.
Math really builds on itself at the stage where you are. Without good algebra calculus isn’t going to work well.
I’d try a different teacher. Online courses or repeating the course with another professor or something.
I agree with the other answers that it depends on the type of programming you end up doing…the nature of the program being developed, but having a background in discrete math is great to have just in case.
From my experience, there can be unexpected problems where you will advantage from having grasp at discrete math. I worked on a project for a telecom company where they wanted a simulation to predict the impact on network coverage if a specific cell tower (BTS) was uninstalled. I ended up relying heavily on the cross-product formula and some ray-casting algorithms to model how coverage would shift in the area.
If you really mean mathematics as in algebra and trigonometry, not much really. But arithmetic is a handy skill. A programmer should be able to at least add and subtract - especially doing UI stuff, which involves dealing with dimensions and positioning of elements on a page. You should be comfortable with numbers and not need a calculator to add up the widths of a few display columns, for example.
