It wasn't that long ago that academically, mathematics was a sub-set of Philosophy

Not really.

The Philosophy described in the ancient use also included the natural sciences, but meant nothing more than the original Greek: "love of wisdom." It was not philosophy as we know it today, and the mathematical arguments used in that time were not rigorous, neither -- for most of the period -- were the natural sciences really science.
