This blog serves as a home and reference site for the undernet’s math channel. You can use it for looking up the current ** problem of the day** (POTD) as well as older ones and their solutions. You are welcome to post your own solutions or problem suggestions as well, for details on that or other ways to contribute to this blog check out the About page.

We invite you to browse the links on the right – in particular our Math Links containing many useful math resources and the blogs of rather well known mathematicians. There is also our (math) **media of the day ** (MOTD), which might contain any sort of media material related to mathematics. It can range from short humouristic animations or graphical illustrations to complete lectures or documentaries. You are welcome to suggest any math media, that you consider to be of interest to others.

Please note that this site is not a blog in the traditional sense – for details see the About page.
