Pre-calculus is the stepping stone for calculus. It’s the final stepping stone after all those years of math: algebra I, geometry, algebra II, and trigonometry. Now all you need is pre-calculus to get to that ultimate goal — calculus. And as you may recall from your algebra II class, you were subjected to much of the same material you saw in algebra and even pre-algebra (just a couple steps up in terms of complexity — but really the same stuff). Pre-calculus begins with certain concepts that you need to be successful in any mathematics course.
If you feel you’re already an expert at everything algebra, feel free to skip past this chapter and get the full swing of pre-calculus going. If you have any doubts or concerns, however, you may want to review; read on.
If you don’t remember some of the concepts ...
