A math degree is pretty strong in the job market but so is an engineering degree (if you're already in the engineering school). Ultimately, I personally would recommend you find something you like. Really, something you tolerate learning about for the next 4-5 years and that you could get good enough grades in.
Every part of the electrical engineering spectrum has math, and it's truly amazing to see how math presents itself in real problems. I use math every day when solving problems at work. Whether it's basic algebra, systems of equations, or calculus. It's also important to have a great intuition on the physics.xAn1zf.
