A torrent tracker is a piece of software which tracks Torrents. It will record the number of leechers, number of seeders, how large the torrent is, what files are contained in the torrent, and how many times the torrent has been downloaded. You can think of it like a statistics tracker for torrents.
The unit of the Maya writing system is the glyphic cartouche, which is equivalent to the words and sentences of a modern language. Maya cartouches included at least three or four glyphs and as many as fifty. Each cartouche contained various glyphs, as well as prefixes and suffixes. There is no Maya alphabet.
Their numerical system is similar to that of the Romans, but instead of Xâs and Iâs they use dots, bars and shells. Each dot has the value of one, each bar the value of five, and each shell the value of zero. This brings us to the main mathematical contribution of the Mayans, the concept of zero.
