I liked the old books. Can only find them in libraries and garage sales. They were cut and dry. We used paper, pencils, erasers and chalk talk. a LOT of chalk talk. All tests were written long form and had to prove. No calculators allowed.
I finally learned I had to work lots of problems to survive and sort of thrive in Calc and Difeq. To do that I got the outline series and went to an empty class room with blackboards all the way around where I went ‘round and ‘round the room for three hours every Tuesday and Thursday afternoon after I finished teaching surveying lab.
Hardly ever used it again but I did use a lot of Algebra, Trig, Numerical Methods and Statistics over the years. I worked with some Phds in controls and found they used quite a bit of calculus. One of the sharpest controls guys I worked with though was a young BS in EE.
In the homeschool community people who want old school math books buy them from India. The text is English and the math is no fluff pure old math.
