Neither is math. My guess is that you will find many more Chinese programmers who understand English comments than those that understand high-school mathematics symbols.
I would venture that any such programmers ought not work on a math-intensive domain like signal processing. Sure, not every programmer has to know high school math. You can, for example, do great work with HTML, CSS, and JavaScript without knowing high school math. But there are certain fields where math is unavoidable. Signal processing is one of them. And the internationally accepted notation for such math is part of what you're expected to know.
BWT, I assume you're not saying China uses different mathematical notation. I wouldn't know about that. If so, then that does undermine my argument.
