I’m at the point now where I’m comfortable saying, “Don’t use the answer book for the second edition for the third edition.” More than 99 percent of the problems are identical, but since I’ve found at least two that are definitely different, that nagging question is always there, “Did I get it wrong or is the book different?”

I started out under the assumption (because I had read it on the internet) that Saxon Algebra 2, 2nd Edition and Algebra 2, 3rd Edition were identical as far as actual questions asked. I can confidently say now, THEY ARE NOT IDENTICAL.

That said, the differences are fairly minor. Other than “getting the problem wrong” and having to figure out why, it’s not like they’re substantive changes. In Lesson 30, question 14, a 12 was changed to 18. The rest of the problem is identical. Just makes the answer different. The actual math performed is quite similar. But still, the fact that this has happened twice makes me want to buy the correct answer key. It’s just not worth the hassle-factor.
