You can't have it both ways. If physics was reducible to pure
mathematics, then physics could not be the 'ontological base level' of
reality and hence everything could not be expressed solely in terms of
physical substance and properties.
Besides which, mathematics and physics are dealing with quite
different distinctions. It is a 'type error' it try to reduce or
identity one with the other.
Mathematics deals with logical properties, physics deals with spatial
(geometric) properties. Although geometry is thought of as math, it
is actually a branch of physics, since in addition to pure logical
axioms, all geometry involves 'extra' assumptions or axioms which are
actually *physical* in nature (not purely mathematical) .
