Your email address is never displayed on Interactive Mathematics or on the associated squareCircleZ blog. Everyone hates spam!


Sometimes cookies are placed on your computer to improve the functionality of the site. A cookie is a small text file that sits in your browser's cache. For example, Interactive Mathematics conducts a poll from time to time and a cookie is used to remember your voting status (voted already, or not voted yet). These cookies will not store personal information about you and will not be used in a malacious way. They do not track where you've been on other sites.

The poll cookie is a persistent cookie, which means it will stay on your computer for a certain amount of time, then disappear.

There is also a mobile device cookie, which is set when visitors choose how to view the site with their mobile device (either mobile version or full version).
