Do you know of any algebra curricula that teach formal algebraic proofs? We did this in my honors algebra I class, but nobody else did, and doing them does not appear to be the norm. But I really think it was valuable training just for logical thinking, as well as mathematical thinking, and it make geometry pretty much of a snap.
I'd love to find one that includes this, or at least some way to guide me so that I could introduce it to them on my own.

I don't really care who did it. I just want you to clean it up.
