Math isn't anything but matter. Math is just another thought construct. A powerful thought construct, but a thought construct nonetheless. As a thought construct it too is material. The electronic impulses on you computer are no different than the ones in your brain.

So yes. Math is also a material manifestation. Life is a material manifestation. Thought is a material manifestation. The problem is with you trying to separate yourself from matter, but the very thing you're using to create that separation is thought. It is the very thing you're trying to get away from, and so you cannot exist separate from thought by using thought. It is a futile and empty game.
