*Who Wants to Be a Mathematician* at the 2010 American Regions Mathematics League Competition

*Who Wants to Be a Mathematician* traveled to Iowa City--home of the University of Iowa and the Midwestern site for the 35th American Regions Mathematics League (ARML) competition--for a rare nighttime event on Friday, June 4. Over 300 students from states extending from Texas to Minnesota took part in the AMRL competition in Iowa City.

In addition, eight four-person teams (representing Chicago, Indiana, Iowa, Michigan, Minnesota, Missouri, Texas, and Wisconsin-Kansas) played two games of a team version of *Who Wants to Be a Mathematician*. The big winners (pictured below) were from Texas, who took home four TI-Nspire graphing calculators from Texas Instruments and $3200 in cash from the AMS.

For each question in the two games, one individual from each team answered on his or her own. Then before the correct answer was revealed, the remaining three team members from each team answered collectively. All points earned counted toward the team total. Each team member answered two questions individually in the games.

The teams from Missouri and Texas were tied at the halfway point of game one, but Texas pulled away from everyone in the second half of the game to win. In fact, the team from Texas answered the individual and team parts of every question correctly. After a slow start, the Minnesota team caught Missouri and the two teams tied for second.

Game two was a wild one. Each of the four teams held at least a share of first place at some point in the game. The winner was the team from Chicago (pictured below), which won by giving correct answers on the last two questions (both individual and team on question 7, and individually on question 8). This earned Chicago (and Texas earlier) four TI-Nspires, \$600, and a trip to the Square-Off Round, in which the first individual to answer correctly would win another \$600 for his or her team and a chance at the $2000 Bonus Question.

Two members from each team played in the Square-Off Round. Bobby Shen from Texas, who finished second nationwide in the individual part of the AMRL competition, signaled in on an algebra question even before it had been read and was correct. So Texas advanced to the Bonus Round.

The team members were allowed to confer on the Bonus Question. They talked for about two of the allotted three minutes and then made up their minds. Their choice was the audience favorite and the correct answer, which earned Texas another $2000. Here are the prizes won by all 32 contestants (for each prize, each person won that prize or cash amount):

**TI-Nspire graphing calculator**from**Texas Instruments,**and**$800**from the**AMS**: Jay Hashop, Kevin Li, Bobby Shen, and Lilly Shen (Texas)**TI-Nspire graphing calculator**from**Texas Instruments**and**$150**from the**AMS**: Eric Auvinen, Charles Du, Derek Hardin, and Kate Rudolph (Chicago)**Maple 14**from**Maplesoft**: Charlie Beard, Audrey Dang, Ravi Fernando, and Maximilian Schindler (Missouri); and Robin He, Soo-Min Kim, Daniel Kriz, and Alex Song (Michigan)by Anton, Bivens and Davis from*Calculus with Early Transcendentals***John Wiley and Sons**: Rohit Agrawal, Martin Camacho, Scarlett Qi, and Tao Wu (Minnesota); and Pavan Kota, Shyam Narayanan, Stephen Rong, and Michelle Yang (Wisconsin-Kansas)from the*What's Happening in the Mathematical Sciences***AMS**: Richard Ni, Shawn Qian, Sachin Shinde, and Lauren Stephens (Indiana); and Tyler Chenhall, Joel Schneider, Luchang Wang, and Shi-Ke Xue (Iowa)

Thanks to the sponsors Texas Instruments, Maplesoft, and John Wiley and Sons, for their continued support of *Who Wants to Be a Mathematician* and for furnishing four times the prizes usually awarded. Thanks also to Steven Condie, ARML Midwestern site coordinator, and Bryan Sullivan, ARML president, for making all the arrangements for the contest.

Coda/overture: Upon arriving at the lobby of the hotel where their rooms were reserved, the *Who Wants to Be a Mathematician* staff learned a new word: "underdeparted" (not a mob movie taking place below the streets of Boston). The reserved rooms were not available because the hotel was, yes, underdeparted. Fortunately, the staff was not overstranded because the hotel arranged for rooms at another location.
