Few people here under the age of 50 have probably had real "real math" as it was once taught in this country. In 5th grade we measured and calculated the area of the schoolground in acres. In high school I had the problem, "If you drop a ball off a cliff and hear it hit 20 seconds later, how high is the cliff?" With my old math I was able to write a 1,000 line computer program to analyze horse races. I was able to derive some of the fundamenal equations of calculus such as pi Rsquared before reading that chapter in the book. I can derive a Pearson product moment around a curvilinear form.
