The point I'm trying to make is that computers "do arithmetic" through digital operations where there is a symbolic representation (through assigning analogue state to discrete symbolic values). Not through transistors operating continuously in their linear region.
Inside neuronal systems there doesn't seem to be a direct symbolic representation - and if there is, the neuronal patterns of somebody doing calculus on paper versus e.g. catching a ball are entirely different.
The symbolic representation is just a language though.
We might not be equipped to understand a language different from the formalisms we came up with.
