No it's not. Not any more than chemistry is a philosophy or history is a philosophy.
> The only difference is that Math adds a few extra requirements in that it is required to stay internally consistent using a given system of logic (in this case, strictly Boolean logic, it's the entire reason why proof by contradiction is even possible).
Philosophy is also required to be consistent (properly, both internally and with the external world), and allows proof by contradiction without relying on strictly Boolean logic.
