>>13362411Absolutely, you'd know more than anyone there. Like Lang it's very in depth. There are much shorter paths if you just want to move on quickly, though (like any random precalculus book). It's amazing someone like Euler wrote a basic algebra book, so I have no clue why people wouldn't use it honestly. And Euclid is perfect, you don't even need the trigonometry book honestly because you could develop it all yourself, but I included the suggestion as a shotcut.
