You mean? Deriving addition and multiplication from physics? That
is impossible.
I'd say that depends on what you mean by 'derive'. Certainly the
idea of addition and multiplication occurs to humans, and even to
some animals, through evolutionary processes.
I meant derive by a logical deduction.
Like we can derive exponentiation from addition and multiplication,
but it is a *very* difficult problem which took seventy years to be
solved (mainly by Davis, Robinson, and Matiyasevich).
