The short answer is no. I think it's a bit of a myth but it's propogated because maths problems are usually well suited to being solved by computers.

So in uni/college, people will get maths problems that they need to solve in compsci subjects but what you will usually find is that the maths is actually harder to solve than the code that is needed to implement the solution.

Once you get into the real world, you'll increasingly find that the problems are largely solved for you, your job will just be to implement them in code.
