Thank you for joining us for MATHCOUNTS Week 2020, powered by AoPS!

MATHCOUNTS is a community united by a love of problem solving...even when we can't meet in person. Below, get links to archived chat transcripts, videos and photos from MATHCOUNTS Week.

Thank You to Our Sponsors!

Our Sponsors Made MATHCOUNTS Week Possible

All of our sponsors ensure MATHCOUNTS can continue to provide the programs, resources and experiences that make learning math fun, including MATHCOUNTS Week. We are incredibly grateful for your support.

In particular, we would like to thank the following sponsors whose contributions directly supported MATHCOUNTS Week:

  • Funding from Raytheon Technologies ensured MATHCOUNTS could celebrate our national qualifiers, funded a record 4 Alumni Scholarship winners this year and enabled the MATHCOUNTS staff to put in extra time to make MATHCOUNTS Week possible.
  • Funding from the U.S. Department of Defense STEM helped MATHCOUNTS to revamp the Math Video Challenge this year and provided MVC Finals prizes.
  • Texas Instruments Incorporated donated amazing TI-NSpire CX graphing calculators to ensure our math super stars were rewarded for their problem solving

Finally, a huge thank you to Art of Problem Solving! In addition to hosting multiple MATHCOUNTS Week events for us, AoPS has been working tirelessly to create a math competition platform, registration system and voting platform—without which MATHCOUNTS Week simply would not be possible.
