Is double majoring in math and science a good idea, and what careers combine math & CS?

I’m a 27 female HSP and introvert, and I’m currently trying to figure out what I want to do. I’m in community college and am soon going to be transferring, but I’m still undeclared and am unsure what I want to do.

I’m good at math, and I’m starting to get interested in computer science, thing is, I don’t favor one over the other, so I’m thinking that I’ll probably try to double major math and CS (maybe with a minor in a foreign language, just because I love foreign languages and learning them). I know that double majoring might be extra work, but if it is a good idea and would make me more marketable, I’m all for it. So, would it be worth it?

As for my second question, even though I’m thinking of double majoring in this, I’m not really sure what are good, stable careers (that hopefully pay well) that combine math and cs, I’ve done some searches, but unless I searched under the wrong thing, I didn’t really get back results that really helped me, so I thought I could come here.
