I know most schools put Geometry between Algebra 1 and Algebra 2 and when I was in high school a long time ago that's what they did. I found Geometry to be tougher than Algebra 2 and thought it should be reversed. It should be obvious that students would have a lot easier time retaining Algebra 1 material if they had Algebra 2 the year right afterwards and not have a year of Geometry in between. On the other hand, that would made Pre Calculus tougher with the gap year of Geometry although fewer students take Pre Calculus and they are likely more advanced students that have a better chance at retaining the information. Also with more students learning Algebra 1 earlier these days I'd feel more comfortable teaching Algebra 2 to younger students (8th grade) than Geometry (why have them learn a totally new mathematics rather than build off the algebra they already know?)
Is there merit to doing Algebra 2 immediately after Algebra 1?

Hi, I had a few conceptual questions about linear algebra and I was hoping someone here could provide insight:
-
What about linear systems makes the math "easier"
-
What would we not be able to do to non-linear systems
-
Is there a non-linear algebra?
-
Who invented computations like determinants, eigenvalues/vectors, SVD, and why? What were they hoping to achieve?
I understand when people complain about the degree of math we learn in school. And sure, if we're talking about classes like trigonometry or calculus, that's valid; I can count the number of times I've had to use SohCahToa or derivatives in my day to day life on less than one hand. But when people complain about algebra, I can't stand it. Can you seriously tell me in your day to day life you've never had to look at a graph? Or that you've never used a simple formula to get an answer? You may not realize it, but when you decided to buy three pizzas for the party you're hosting based on the number of attendees, you just input a variable into the equation (# of pizzas = # of attendees * average portion eaten per attendee). And the reason you don't think about it like that is because it's so ingrained into your mind - almost like someone did a good job of teaching you it. Math is far more complicated than what we use on a day to day, and I have no issue with complaining about mandatory higher level math in school, but algebra is so genuinely useful and so universal that it's insane to imply that a generation of kids who don't learn it would be better off.
