Unfortunately it is more work than that to get math working. You need system libs latex, dvipng and lib OCaml.
As it is not a vps hosting we cannot install those ourselves so it will definitely take some time even if its possible (could be not).
Until we do the formulas will have to use images.
If we see that wiki is really useful, should be our primary approach and the budget allows, then we can rent a vps host.
So please try to make it useful as it is now and I will ask around about the math extension.

EDIT:OCaml is not php lib
