I recommend @mscroggs's maths puzzle advent calendar. mscroggs.co.uk

Pick a quadratic. Will it factorise? @Pecnut and @mscroggs investigate in this blog from the archives chalkdustmagazine.com/blog/man

@alexdbolton $\mathrm{e}^{x-1}$

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.

Do you love maths magazines and the first number that is neither prime nor semiprime? Then you'll love our 8th issue! chalkdustmagazine.com/

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

$\sqrt{\sqrt{9} - \sqrt{8}} = \sqrt{2} - \sqrt{1}$

Issue 08 of @chalkdustmag is finished and has been sent to the printers.

Mathematical fact made entirely of straight lines (based on @Pecnut's idea):
$\left|\frac{\mathsf{\Xi}}{|\mathsf{\Xi}|}\right|=1$

... or maybe this is worse:

$x+\mathrm{x}=\mathsf{x}$
$\mathsf{x}+\mathrm{x}=4x$
$\mathsf{x}+x=3\mathrm{x}+1$
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 $\color{green}x$.

${\color{yellow}x} + {\color{blue}x} = {\color{green}x}$
