Does anyone know where I can get a complete list (that is preferably well organized) of topics from arithmetic - pre-calculus? I've had difficulty finding one resource that is comprehensive for arithmetic. Maybe I am being too picky... I have about 9 full pages of topics for arithmetic so far that have been put together piecemeal, but it would be awesome to find one comprehensive book/online resource. It's clear that textbooks are a good starting point, but to understand the logic and how to derive formulas/concepts there needs to be additional resources. A little rant: If I could put mathematical learning into two categories - execution and logical understanding. Someone can be great at learning how to execute formulas, but not see how things connect (maybe this is a no-brainer!). Understanding the logic isn't explicitly taught (at least in my experiences). This is clear from our tutoring center. The majority of the tutors can tell how how to find the answer, aka use this formula, but can't explain the why. There's a fellow with a B.S. in math and of course he can explain everything backwards and forwards. Am I trying to learn above my level? I am taking calc 1 in December. Being a physics major I really enjoy going to the core of understanding the 'why' in concepts, but it takes up so much time and it's tough with full-time work and school.
