Introduction

Hi Everyone,

I am a hedgehog who likes Message Board halping, funny pictures, emoji wars, and AoPS Wiki contributions. Keep these fun things coming!

This hedgehog represents my attitude towards mathematics--victorious and enthusiastic!

And here is my personified self-portrait:

AoPS Bio

Jerry graduated from Northeastern University in 2018 as a mathematics and computer science combined major. He has eleven years of experience working with students. He has served as an AoPS instructor and a message board moderator since 2019. During his last two years in high school, he served as the math club president and prepared lively lectures on contest math. As a result, he inspired many kids to get interested in math and participate in math competitions (such as AMC and ARML). For the last eight years, he has worked with Math League to write math contests for students from grades 4 through 12 in the USA. In his mind, nothing is more rewarding than educating tomorrow’s bright minds. In 2020 he published the book English-Chinese Mathematics Encyclopedia: Algebra, Geometry, and Pre-Calculus in Tsinghua University Press in China. In his spare time, he loves contributing to the AoPS Wiki and playing chess and all sorts of board games, especially Scotland Yard, and Samurai.

AoPS Wiki Contributions

Below are my contributions to the AMC/AIME Problems' Solutions in the AoPS Wiki. I understand that in this communal Wiki, we all have to collaborate and make compromises. In any of my solutions, if you find flaws and/or want major revisions, then please contact me via my user talk page or the private messaging system before you take action. I am sure that we can work things out.

Thank you for your cooperation, and hope you enjoy reading my solutions.

Finally, here is my YouTube channel (MRENTHUSIASM) for the video solutions. Go ahead and subscribe--you know you want to. $\smiley{}$
