But they're often still better than other freely available resources. Math errors are probably a result of the editor not knowing it correctly, not malice. Have you tried correcting the ones you found? I find math on Wikipedia really hard to get right. If you want to express it completely accurate, many people with little knowledge of the domain won't understand it. If you want to make it accessible, you often need to make some compromise. For someone looking up a simple fact or theorem, having a simple description can be best, even if it's not strictly correct.
