American Regions Mathematics League Competition

ARML is a late-spring team mathematics meet built around four different forms of problem solving: a team round, an extended proof-based power question, an individual round, and relays in which one student's answer feeds the next. Teams represent schools, regions, or math circles and compete together rather than submitting a standalone project. The main tournament is normally held in late May or early June at simultaneous university sites, with the organizer publishing the year's sites, housing, fees, and registration instructions.
