Question: If you start with $1 and, with each move, you can either  double your money or add another $1, what is the smallest number of  moves you have to make to get to exactly $200? Mark Sellke, an 8th grader at Klondike Middle School in West  Lafayette, Indiana, correctly answered this question in less than 45  seconds this past May to become the 2010 MATHCOUNTS individual champion. Yesterday, President Obama met with Mark, the winning MATHCOUNTS team  from California, and the individual runner-up of the competition.  During their visit to the White House, these elated “mathletes" talked  to the President about their aspirations—including working for NASA and  becoming a math professor.
 
The President congratulated the students on  their accomplishments and emphasized the importance of science and math  to the Nation’s economy, security, and competiveness. He also confessed  to a more parochial pleasure in getting to know them, declaring that he  would be calling upon them next time Sasha or Malia stumped him with a  math homework question. Not everyone needs to be able to figure out as fast as Mark did that  it takes (spoiler alert!) at least nine moves to get that $200, but the  United States will need more stars like Mark and his co-winners if we  are to meet the President’s goal of once again having the highest  proportion of college graduates in the world by 2020. One assessment  shows American 15-year-olds now rank 21st in science and 25th in math  when compared to their peers around the world.
That’s one reason why the President launched the “Educate  to Innovate” campaign to motivate and inspire students to excel in  science, technology, engineering, and mathematics (STEM). That campaign  has already helped to raise more than $500 million from the private,  nonprofit, and philanthropic sectors for the creation of innovative  public-private partnerships to attract, develop, reward, and retain  outstanding educators in STEM subjects. So congratulations to America’s newest mathletes. And to the rest of  the Nation’s students: Let’s get to work!
