A small site, a wide world

A small collection of browser-based mathematics tools has quietly become a study aid in 120 countries. This is what its first seventeen months of use look like. For a closer look at usage within the United States, see the state-by-state breakdown.

Detailed breakdown

The top 15

Nearly nine in ten of all users come from the fifteen countries below. Beyond them, a long tail of more than one hundred countries each contribute a handful of learners — students who found the site through search, a textbook reference, or word of mouth from an instructor. Click United States for a state-by-state breakdown.

Reach by region

The site reaches every inhabited continent. North America leads on raw volume, but per-capita engagement is highest in small, English-fluent regions where access to commercial mathematics software is uneven.
