I don't know how to derive fermions and bosons from nothing but arithmetic
but you can do the next best thing. If the Schrodinger wave function for a
particle is a odd function, that is F(x) = -F(-x), then it's a fermion and
the probability of 2 fermions occupying the same quantum state is zero, in
other words it obeys the Pauli Exclusion Principle and is the reason that
the ground beneath your feet, which is made of fermions, is solid and you
don't sink to the center of the Earth.
If the Schrodinger wave function for a particle is a even function, that is
F(x) = F(-x), then it's a boson and it can ignore the Pauli Exclusion
Principle and is the reason light rays, made of bosons, don't scramble each
other when they collide at right angles, light particles can occupy the
same quantum state and thus can pass through each other and be completely
unaffected; it's the reason the light rays that enter our eye are not a
hopeless chaotic jumble of information randomized by a astronomical large
number of collisions with other photons.
