**Luke Robitaille**, a homeschooled freshman from Texas, put on a great performance on January 19 winning the 2019 *Who Wants to Be a Mathematician Championship* at the Joint Mathematics Meetings in Baltimore, Maryland. Here's Luke just after his victory:

The 12 contestants who qualified for the 2019 championship (see short profiles of the contestants):

**Front**, left to right: **Praneet Mekala** (Massachusetts Academy of Math and Science at WPI), **Anudeep Golla** (Fairview High School, CO), **Steven Qu** (Montgomery Blair High School, MD), and **Olivia Guo** (Concord College, UK). **Back**, l to r: **Tristan Shin** (Canyon Crest Academy, CA), **Brian Liu** (High Technology High School, NJ), **Luke Robitaille** (Robitaille Homeschool, TX), **Max Guo** (Sycamore High School, OH), **Howard Halim** (University of Toronto Schools, Canada), **Michael Han** (Iowa City West High School), **Connor Gordon** (American Heritage School, FL), and **Alex Chung** (Thomas Jefferson High School for Science and Technology, VA).

See the video of all the game action below--which includes a reading by the AMS Math Poetry Contest winners--a description of the semifinals and finals, as well as videos and photos from the awards breakfast that took place before the games.

(Semifinal two starts at about 40 minutes, math poetry around 1:16 [hour:minutes], and the finals start about 1:25.)

It was a *Who Wants to Be a Mathematician* first, as three contestants in each semifinal answered every question correctly, which earned all six of them a spot in the finals. Fortunately there were enough lecterns on stage to accommodate them in the finals. Tristan missed out on tying for first in game one by only 100 points.

The six contestants who made it to the finals were (left to right): Brian Liu, Connor Gordon, Howard Halim, Michael Han, Luke Robitaille, and Steven Qu. Their finish in the finals determined their finish in the semifinals, and thus, their prize and cash amounts. Luke started out well, answering very quickly, and continued throughout the finals, answering incorrectly on only one of the questions that he was first to buzz in on. Brian was within striking distance of Luke on the last question, but Luke answered correctly on that question, so Brian wound up in second place. Each is pictured below, along with their giant uncashable checks, with AMS President Ken Ribet and AMS President-elect Jill Pipher .

Maplesoft was nice enough to award the second-place semifinal prizes to all four of the other contestants. They are pictured with AMS President Ken Ribet, AMS President-elect Jill Pipher, and Maplesoft's Tina George.

Below is a list of the prizes and cash won by each of the 12 semifinalists. For each cash prize, the contestant wins that amount and a matching amount is given to the math department of that student's school. Luke, who is homeschooled, directed his matching amount to his local math circle, the Mid-Cities Math Circle.
