You think so? I betcha I could teach you something that is calculus yet dead simple. (I used to teach Math at Valencia College.) Go to YouTube and search “derivative” and “power rule.” If you know the definitions of a coefficient, a variable, and an exponent, you’ll crack it in 10 minutes flat.

I took calculus in college. I have not had much use for it. In my career we used cross tabs all the time and in my later years I taught the newcomers how to understand them. It was more or less teaching Algebra 2 in a more meaningful way. I love the logic of math.
