How do materialists explain the existence of logic and mathematical rules?

Take something like the pythagorean theorem. Some mathematicians invoke a form of platonism and assert that the rule that a2 + b2 = c2 exists conceptually, without material properties. What is the materialist retort/response to this idea? Do mathematical relationships exist outside of physical phenomena?

Materialists recognize that ideas exist, you know. How could materialism itself exist as a concept without material properties if one didn't permit ideas? What (most) materialists would claim is that such ideas exist only because there is a being exists to have them, and what they dispute is the idea that such ideas exist beyond beings that are capable of conceiving them.
