Is there such a thing a better sequence of topics in learning Algebra 2. Or does it even matter? I was wondering because the old Larson texts which Chalkdust uses and the newer texts from 2004 onwards have different sequence of topics. They have the same sequence from Prerequisite to Chapter 2, then differs . I am hoping for your thoughts on this. Which one has a better sequence for a non-mathy kid?

This is from the older Larson texts

The newer editions begin with review, typical of many math books these days.

It appears that Systems of Equations have been bumped from chapter 8 to chapter 4. The old book had a section on conics, the new ones have a chapter.

Ultimately, one could say that if the material is covered, the order does not matter. What I can't tell you is if the Systems work that now appears early on is integrated in some fashion in the later material. Students study determinants in chapter 4 and are probably using their calculators, I would suspect. This may add to the motivation in having the material earlier. Textbooks often like to demonstrate calculator use beyond the basic functions and simple graphs. Of course, this is speculation on my part, since I don't have the books in front of me.

From the table of contents, I really do not see that much variation in the ordering.
