We also made an environment to run through a game, with or without numbered pieces showing the order of play. Here the envionment is hexgame or hexgamelabels and moves are \hexmove{row}{column} (the player colour alternates).

The basic diagram is a hexpicture environment, then a command like \hexboard{11} will render a blank 11x11 game board.

You place pieces with \hexcounter{row}{column}{player} e.g. \hexcounter{b}{1}{A}.

@peterrowlett "Quantities" is far too narrow. "Logical structures" maybe.

Lessons from my #proofinatoot writing:

1. The mastodon interface has no markdown preview; can admins add one? For example, here's one: https://kerzol.github.io/markdown-mathjax/editor.html

2. Greek letters are *expensive*; latex \(\alpha\) is 6 characters, plus 4 for math mode. Unicode α is only 1.

3. All those extra spaces in my easy-to-read latex source add up!

Add and subtract \( u(x+\delta x)v(x) \) in the numerator. Then

\( (u(x)v(x))'=\lim_{\delta x\to 0}\frac{u(x+\delta x)v(x+\delta x)-u(x+\delta x)v(x)+u(x+\delta x)v(x)-u(x)v(x)}{\delta x} \)

\( =\lim_{\delta x\to 0}u(x+\delta x)\lim_{\delta x\to 0}\frac{v(x+\delta x)-v(x)}{\delta x}+\lim_{\delta x\to 0}\frac{u(x+\delta x)-u(x)}{\delta x}\lim_{\delta x\to 0}v(x) \)

\( =u(x)v'(x)+u'(x)v(x). \) #proofinatoot
