It's far easier to understand the concepts piecemeal. Methods are easier to understand if you already grok functions. Integrals are easier to understand if you already grok derivatives. When learning these things, you're often fed an over-simplified explanation so that the instructor can go on to cover something more advanced. The problem is that now you're trying to learn something more advanced before you've got a solid understanding of the primitives.
