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

Pick a quadratic. Will it factorise? @Pecnut and @mscroggs investigate in this blog from the archives http://chalkdustmagazine.com/blog/many-quadratics-factorise/

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

Do you love maths magazines and vertices of cubes? Then you'll love our 8th issue! http://chalkdustmagazine.com/

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

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):

\(\left|\frac{\mathsf{\Xi}}{|\mathsf{\Xi}|}\right|=1\)

@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 \(\color{green}x\).
