You may have noticed I just updated an old post from April 2016. Here's why - it's relevant to the upcoming SAT; I often refer people to my blog; and sometimes the interface for Weebly, the service I use to publish and host this site doesn't show superscripts, subscripts, Greek letters, and so on, in the way they appear when I write the posts in MS Word or another program. So when I see a problem (sometimes almost a year later), I fix it! Feel free to let me know if you see a problem with one of my blog posts.
