I assume you mean math/science is fact-based not faith-based... math/science is based on facts which you can show to another person... I can show you that 1 + 1 = 2... I can show you how to do an experiment that proves the Earth is spherical... science shows you the evidence, rather than asserting claims without facts or evidence which can be shown to someone (the way religion does it)
Science is based on observations, and the scientific hypothesis.
This is different than "facts."
Math is based on mathematical proofs.
All facts are observations... that's a fact, Jack
Science is based entirely on observations... repeatable, verifiable observations

"Scientific facts are verified by repeatable careful observation or measurement"
Religion doesn't appear until someone interprets their observation of facts.
Science theory is something that knowably is open to change. Therefore it is knowably not known to be fact.
When someone believes a science theory to be true and factual, he is placing it into the realm of religion for himself. Why? Because he knows that the only fact of the theoretical point is that it is a theory. So, he is basing his interpretation on the only fact available... that the science theory is factually known to not be a fact. For him the science theory point has become religion, even if it is not religion for others who do not believe that it is fact, but who only understand that it is theory.
