I'm not a programmer but. . .unless you're coding an explicitly math-intensive application, aren't there tools that could do any math that's required? Of course, the tool would have to come from a trusted source.
Like I said, might not be a problem for a simple web app, but have you ever tried writing a game? For even the simplest game I end up using a lot of (fairly simple) math, linear algebra and some physics. If you start doing stuff in 3D, you'll need even more.
