If so, they have a knowledge of mathematics that won't get them very far, though it may be enough for their life-styles. It's sort of like a small society living in a valley which to them is the whole world, since they've never been out of it. They think it's the whole world, but they're wrong.
You are talking about a culture's *knowledge* of mathematics, not mathematics itself. This is a common problem with sociologists, etc. -- confusing what people know or believe about a subject with the subject itself.
