Solve 1/a = 1/b + 1/c

I think the first step is to multiply both sides of the equation by ABC.

(abc)(1/a) = (abc)(1/b + 1/c)

bc = ac + ab

Is this OK so far?

In the right path.

Thanks but I didn't ask you to solve for c.

I often find myself going through a textbook like walking in the park on a sunny day. I then reach a certain chapter or section that requires knowledge of all the previous math material I have learned or thought I learned. Confusion sets in to create a stumbling block that keeps me wondering if I truly learned anything at all in my previous math courses or chapters or sections that I just completed. Why does this happen? How do I keep myself from forgetting the earlier chapters or sections in math textbooks?
