The ability to walk without falling over takes a lot of computation, even if it seems effortless.
At least in so far as living macroscopic beings are concerned, they're all doing computation of some sort by processing environmental information and using the results to produce behavior. They're about as good at math as any other computer programmed to reproduce those algorithms.
So long as "processing" information isn't the same as actually producing that behavior, as in the case of crystal growth, they're doing something besides what they're doing.
Though I'd prefer to think that crystals are actually doing math too, but they're so good they don't even need to think about it.

Neither is an issue that some way of thinking might raise more questions than it answers. Actually, if any of those questions is both interesting and solvable, that is a virtue.
In sum, I was just trying to see through what angle OP was framing their point.
[1] You don't really need to understand _how_ you're moving your arm. You just do it -- it's on autopilot.
Highly recommended if you're interested in philosophical discussions about this sort of stuff. I'm finding it highly entertaining and deliciously provocative.
You can also claim that Google is a giant lookup table. They should stop hiring computer scientists and start repurposing brains!
Saying the brain literally computes is making a philosophical claim as to what exists, as opposed to a useful metaphor.
