I use amsmath extensively and there's no problem. I don't escape my math environments and IMO you shouldn't as they would then be ignored by ox-odt and ox-html. As Eric point out you'd typically use amsthm for proofs. You need to add this to your document. The proof env. is predefined in amsthm, though.
