Mathematics

Mathematics is an academic discipline in which the properties of numbers and the methods of manipulating them are studied. On Tetro, mathematics falls within the realm of systemics and is usually taught during primary schooling.

Number Systems
Tetrian methods of representing numbers vary between Humans and native species. While native Tetrians have used a trinary (base three) number system since the dawn of their civilization, the Humans transplanted to Tetro 400 Earth-years ago have held fast to their decimal (base ten) system, despite the inconvenience of converting between the two. Within the Lost Colony, decimal numbers are used exclusively since the population is predominantly Human. Elsewhere, the prevalence of each system varies with the percentage of Human population within the region. This has resulted in some cities having signage for distances and prices that includes both trinary and decimal numbers written in Tetrian and English. With each number needing to be written four times, signs in these areas are significantly larger.
