    Glad the site was helpful! Helping spread the word with people it could help (educators, students, curious autodidacts) is great. There are BetterExplained books/courses you can ge…

    Wow, that's awesome to hear! One of my fears is having to keep blogging continuously, but luckily math is pretty evergreen, so my intermittent writing schedule doesn't punish me to…

    Shameless plug, I made https://instacalc.com (pastebin for calcs) for back-of-the-envelope number crunching. Fast, free, gets out of your way.
