The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.
View the web archive through the Wayback Machine.
Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.
Liveweb proxy is a component of Internet Archive?s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.
Math Machine is a simple game that challenges both your concentration and math skills. Once you launch the skill, you can choose from two activities.
Math Facts can be used to drill basic math operations, such as "5 plus 6" or "4 times 8". Just say, "Play math facts," or "Test addition facts up to five."
Operations Challenge will test your concentration and math speed. You will start with a simple problem, such as "5 minus 3," but each successive problem will add another operation. How far can your skills take you? Just say, "Play the operations challenge," or "Try the operations challenge with five operations" to get started.
If you didn't hear a problem, just ask Alexa to repeat it.
NOTE: For the Operations Challenge, all operations should be performed in the order in which they are spoken, so 5 - 2 * 3 should be calculated as 5 - 2 = 3, then 3 * 3 = 9.
