I'm not sure how to translate this into English. That may be on my end, however.
Here's how I view math: It's a language. Any equation can be translated into any language (well....any language that includes numbers higher than five and the number zero, anyway). It's a very precise language, and often deals with very abstract concepts, but none the less, it is a language.
That in no way separates it from reality. Proper concepts are derived from perception, ultimately (though the number of steps between the two can approach infinity). Mathematical concepts can be thought of as the ultimate conceptualization--it deals with the inter-relationships between things, rather than things. y=mx+b is more a statement about how y, m, x, and b interact than it is anything else. And the precision adds certain value to the convesation--because it is so precise, one can do things with the mathematical language that a more organic language like English or French or Japanese simply can't, due to the error bars. Compare "when one goes up, the other goes down" with "y=1.75/x", for example.
First, you can't say that with any certainty. We don't know the fundemental features of the universe we live in. If we did, to quote a comedian, science would stop.
Second, so what? English does the same thing. ANY living language MUST correspond to, describe, represent, and/or predict every known feature of the universe we live in--for the simple reason that if a language lacks a word or phrase that does so, one will be invented.
Third, this leaves entirely open the question of whether math is somehow a metaphysical reality (in the Aristotilian and Objecivist sense, not the Buhdist or mystical sense) or if it is merely an epistemological necessity. In other words, this does nothing to determine whether math is something inherent in reality, or something inherent in the human mind. (My standard caveat: I've no interest in discussing Objectivist philosophy here; I include it in the previous sentence merely to provide those curious with how I define "metaphysical" with the definition I'm using.)
If math is, than yes, I'd agree. However, since math is the product of human cognition, we can't say that--at least, not without far more proof than we have thus far. I believe that ANY sufficiently precise language would result in the same advantages as math currently has.
