....
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"
