## About this program

## Overview

The **American Regions Mathematics League (ARML)** is the premier annual on-site team mathematics competition in the United States. Regions, states, and large math programs field **15-student teams** that compete simultaneously at university sites (historically including Penn State, the University of Iowa, and UNLV) on the first weekend of June.

## How It Works

- **Team round:** 10 problems solved collaboratively
- **Power question:** a deep, proof-based multi-part problem attacked as a full team
- **Individual rounds:** short-answer problems under time pressure
- **Relay rounds:** answers pass between teammates, so speed and accuracy both matter

## Why It Matters

- ARML sits a level above most school math team events — many state and regional all-star teams select members competitively
- The power round builds proof-writing and mathematical communication rarely tested elsewhere
- Making a regional A-team is a recognized distinction in the competition-math community

## Getting Involved

- Join your school's math team and qualify for your state or regional ARML team (selection is usually based on local contest results such as AMC/AIME scores or tryouts)
- Many regions also run practices in the spring leading up to the June competition
