Article Count Progress

We have reached 0% of our goal of 10100 articles.

Googology for everyone!

On this wiki, we all share a profound love for numbers, and we want the beauty of mathematics — and of course its endless utility! — to reach everyone worldwide. Unfortunately, many countries stricken by poverty lack resources for quality public education in math and science. This is an especially close problem to the younger members of our community; there are many kids their age who have no access to math education.

You can help bring better educational resources globally. One thing you can do is donate to Save the Children, a UK-based non-governmental charity dedicated to children's rights. In particular, they offer a gift catalog allowing you to donate a specific item to reach out and bless a faraway child or community. Click the button below to see what options you have:
