American Airlines is a major US-based airline headquartered in Fort Worth, Texas, within the Dallas–Fort Worth metroplex. It is the world's largest airline when measured by fleet size, scheduled passengers carried, and revenue passenger mile. American, together with its regional partners and affiliates, operates an extensive international and domestic network with almost 6,800 flights per day to nearly 350 destinations in more than 50 countries. American Airlines is a founding member of the Oneworld alliance, the third-largest airline alliance in the world. Regional service is operated by independent and subsidiary carriers under the brand name American Eagle.
American Airlines and American Eagle operate out of 10 hubs, with Dallas/Fort Worth (DFW) being its largest. The airline handles more than 200 million passengers annually with an average of more than 500,000 passengers daily. As of 2019, the company employs nearly 130,000 people.
The American Mathematics Competitions (AMC) are the first of a series of competitions in secondary school mathematics that determine the United States team for the International Mathematical Olympiad (IMO). The selection process takes place over the course of roughly four stages. At the last stage, the Mathematical Olympiad Summer Program (MOP), the United States coaches select six members to form the IMO team. The United States Math Team of 1994 is the first of the only two teams ever to achieve a perfect score (all six members earned perfect marks), and is colloquially known as the "dream team".
There are three levels:
Students who perform well on the AMC 10 or AMC 12 competitions are invited to participate in the prestigious American Invitational Mathematics Examination (AIME). Students who perform well on the AIME are then invited to the United States of America Mathematical Olympiad (USAMO) or United States of America Junior Mathematical Olympiad (USAJMO). Students who do exceptionally well on the USAMO (typically around 30 students) are invited to go to the Mathematical Olympiad Summer Program (MOSP or more commonly, MOP), and six students are selected from the top twelve scorers on the USAMO (through yet another competition, the Team Selection Test (TST)) to form the United States International Math Olympiad Team.
American Mathematics Competitions is also the name of the organization, based in Washington, DC, responsible for creating, distributing and coordinating the American Mathematics Competitions contests, which include the American Mathematics Contest, AIME, and USAMO. The American Mathematics Competitions organization also conducts outreach to identify talent and strengthen problem-solving in middle and high school students.
