Hello everyone, I would like to ask if someone could point me to a good book, that I could use to relearn algebra. I am though, not looking for a regular textbook (like in schools where you learn the formula), but would love something that would teach me the theory behind all the algebraic rules. Also, after mastering (quite a broad term I assume) basic algebra, would moving on to linear algebra be better or differential algebra? Or is there something I should master before them as well. Thank you very much for your suggestions!
