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?
Being comfortable with basic back-of-the-envelope math can be a huge benefit. (Full disclosure: i am a math major who is now a programmer)
Over my career I have several examples of projects that have saved weeks worth of dev time because someone could predict the result with some basic calculations. I also have several examples where I have shown people some basic math showing that their idea is never gonna work, they don’t listen and do it anyway, and I see them 1 month later and the project failed in the way i predicted.
A popular (and wise) saying is that “Weeks of work can save you hours of meetings”. I think the same is true for basic math. “Weeks of coding can save you minutes of calculation”.
You can definitely be a successful programmer career without great math skills. Math is a tool that can help you be more effective.
Depends on the programming job.
In my amateur experience, the most difficult math I had to do was use the Pythagorean theorem to calculate a point that was spinning around an other point.
But I can see needing to be able to use matrices in some instances.
Being good at math allows programmers to code more efficient systems. Instead of doing multiple complicated lines, it could all be incorporated into a single efficient equation.
Most of programming is just logic based. Although math is also logic based. So take from it what you will.
Yep, truth tables mostly. Math is mostly useful in game programming.
And graphics.
Statistics is also important in a lot of areas if your doing data analysis.
As many have already said, the math needed will depend on what type of work you’re looking to do. Writing business software, for example, rarely requires more than basic arithmetic.
However, I think that the logical thinking skills that are needed for math are also necessary to be a good software engineer.
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’ve been a full stack dev for about 11 years. I do some basic algebra but that’s about it.
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
Totally depends what you end up working on as a programmer. If it’s web apps, you’ll be totally fine. All you need is basic arithmetic. Writing a game engine? You’ll need to know some basic to moderate matrix maths…
If you’re doing formal verification using unbounded model checking… good fucking luck.
On average I would say most programming tasks need very little maths. If you can add and multiply you’ll be fine. Definitely sounds like you’ll be ok.
Math underlies programming in a similar fashion to how physics underlies automobile driving. You don’t ever need to know about newton’s laws of motion to pass your driver’s license and never get a ticket until you die. At the same time, I will readily claim that any driver that doesn’t improve after learning about newton’s laws of motion had already internalized those laws through experience.
Math will help your intuition with how to tackle problems in programming. From finding a solution to anticipating how different constraints (notably time and memory) will affect which solutions are available to you, experience working on math problems - especially across different domains in math - will grease the wheels of your programmer mind.
Math on its own will probably not be enough (many great mathematicians are quite unskilled at programming). Just as driving a car is about much more than just the physics involved, there is a lot more to programming than just the math.
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.
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.
Don’t need a degree, but computer programming is fundamentally logic and algorithms. You need to have internalise reasoning logically. In some ways critical thinking is closer to programming than trig is.
Programming and math are both heavily rule-based and logic-based, which is why people say if you’re good at math you may be good at programming.
90% of programming I have seen after a decade plus of doing it full time is minor changes being made to code that was already made by someone. Likely not documented. Likely already changed in a dozen little ways. Math isn’t the problem. Understanding what the guy who wrote it is often the problem.
Oh and you can’t ask them because they likely don’t work here anymore.
Being a programmer is more like being a detective than anything else unless you work for a small company.
Spot on. And I’ve found it’s even that bad at small companies too, if the company is more than five years old.
Programming is Concrete Math and becomes more and more Math the less abstraction you expose yourself to.
Both are fields you have to engage in problem solving, the better you are in one, the better you are in the other.
Don’t confuse Math with pure arithmetic operations though, its just the base concept which provides the fundament you’re building upon as you dig deeper.
I for example was quite bad at Math up until I got interested in IT, because then I had a reason for learning and be excited about it, but I guess thats a heavily subjective thing.
Engaging with interpreted languages and solving problems on certain sites with those also helped in further developing my problem-solving skills, which made Math easier for me.
I failed calc2 and am gainfully employed as a mid/upper level software engineer.
One guy at work really saved the day because he’s good at math, and made a very slow process much faster because he knows … uh… vector math? He did magic with numpy
