Math is hard?

Maybe it is. I know I suffered badly when I took calculus in college; though algebra and geometry in high school weren't awful, they were the courses I had to work hardest at to get decent grades (as opposed to all the extra work I did in the courses I loved) except maybe, now I think about it, organic chemistry. And that was so long ago I don't even remember any calculus...

Anyway, this post is to point you at Mark Chu-Carroll's Good Math, Bad Math "Basics" series. He's explaining a lot of the basic concepts of math - Mean, Median, and Mode; Normal Distributions; Standard Deviation; Margin of Error; Natural Numbers and Integers; Recursion and Induction; Correlation and Causation; and Logic (so far).

If you want to understand numbers and how to use them - and how to avoid being fooled by people who use them dishonestly, or ignorantly, then this is a series for you.
