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.
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.
