Aaarg, I'm using \(\epsilon\) and \(\varepsilon\) (for two different values) in the same equation. I fear it may be time to burn this laptop and start my PhD again from scratch.

This has to be the weirdest setting for a sci-fi novel. This plot synopsis is so bizarre!


\[\sqrt{\sqrt{9} - \sqrt{8}} = \sqrt{2} - \sqrt{1}\]

... or maybe this is worse:

Find \(x\), \(\mathrm{x}\), and \(\mathsf{x}\).

@mscroggs Yep that's why I was wandering if you considered these x's different variables or not. If you are, that actually defines a plane in 3 dimensions!

The absolute worst way to write a simultaneous equations question:

\({\color{yellow}x} + {\color{blue}x} = {\color{green}x}\)
\({\color{green}x} + {\color{blue}x} = 4{\color{yellow}x}\)
\({\color{yellow}x} + {\color{green}x} = 3{\color{blue}x}+1\)
Find \(\color{yellow}x\), \(\color{blue}x\), and \(\color{green}x\).

\({\color{yellow}x} + {\color{blue}x} = {\color{green}x}\)
