I am an professional that has rarely used math over the last 20 years. Well, anything outside a spreadsheet and basic formulas.
My son, who is quite bright, is now getting to an age where I am finding it difficult to help him with this studies. So, I want to relearn what I lost. From what I remember, the progression is Pre-Algebra, Algebra, Geo., Trig., Pre-Calc, Calc... That right? Any new and fun ways to learn? Just pick up books and go for it?
I am doing this for me and him, so either way, I going to try. Just want to make it as efficient as possible.
