Philosophy

Hard challenges, made fun, are thrilling. If you’re currently learning any math subject from Pre-Algebra through high school Geometry, but find it easy (or even boring), you’ve come to the right place. We’ll guide you to love thinking hard until you crack difficult problems. You’ll learn the joy of inventing your own ideas. This new power will make it easy for you to learn anything in the future.

“I have done several online courses with AOPs and mymathcounts. I felt that your course was the best of them all. I liked that your solutions were very smart and clear. It made me think. I also liked the fact that you gave multiple explanations to solve the same problem. I am looking forward to the next Module. I would give 5 stars.”

“Geometry Tools is a great course if you want to learn more about Geometry. Professor Po Shen Loh teaches a lot of great tricks that you can use to solve some difficult problems. I have learned a lot of tricks and tips, including how to square a number, that ends in 5, in just a few seconds. After I completed only 15% of the course, I learned a lot of material that I had not learned in school. I improved greatly on most of my geometry tests. I am very happy about my improvement in Geometry and plan to take the Module 3: Combinatorics Tools and Module 4: Algebra Tools. Thank you, Professor Po Shen Loh, for taking your time to make videos to try to help younger people, and I hope you make more courses! ”

“This is a very fun (but hard!) course. I like how the problems are given to introduce new concepts and the solutions are very clear, and how even though there's a lot of stuff covered, it's presented in only a few problems.”

“Best learning system ever! I love how we do only a few questions at a time and figure it out in different ways instead of rushing everything up. I got some questions wrong, but that's how I learn! Keep up the hard work!”

“This is the best maths course I ever had! Prof Loh gives us challenges for us to solve and then he explains it clearly himself. The weekly exams help, too. This is indeed the best maths course.”

Course Features

  • LIVE

    You’ve never seen anything like our live video math classes before. They’re nothing like the Zoom classes everywhere else. They’re inspirational. See LIVE.

  • Or Self Paced

    If you’d prefer to learn on your own schedule, we’ve also packaged our entire curriculum into high quality video lessons you can watch yourself — 100% taught by Prof. Loh himself. See demo.

  • Invention Oriented

    Our curriculum is designed to teach you how to invent. Not to memorize and repeat. We cover the concepts in middle and early high school math competitions like MATHCOUNTS, AMC 8, and AMC 10, as our source of challenge.

Curriculum

  • Module 0: A sampler of the 4 main areas of mathematics: algebra, geometry, combinatorics, and number theory

  • Module 1: Lays a foundation for Algebra, enabling students to explore more useful and deeper topics covered in this course series

  • Modules 2–5: Each module rapidly covers fundamental math competition tools in one of the 4 areas of algebra, combinatorics, geometry, and number theory

About

  Po-Shen Loh 

Po-Shen Loh is a social entrepreneur and inventor, working across the spectrum of mathematics, education, and healthcare, all around the world. He is a math professor at Carnegie Mellon University, and the national coach of the USA International Mathematical Olympiad team. He has pioneered innovations ranging from a scalable way to learn challenging math live online at comparable engagement to live-streaming entertainment, to a new way to control pandemics by leveraging self-interest.

As an academic, Po-Shen has earned distinctions ranging from an International Mathematical Olympiad silver medal to the United States Presidential Early Career Award for Scientists and Engineers. His scientific research considers a variety of questions that lie at the intersection of combinatorics (the study of discrete systems), probability theory, and computer science. As an educator, he was the coach of Carnegie Mellon University’s math team when it achieved its first-ever #1 rank among all North American universities, and the coach of the USA Math Olympiad team when it achieved its first-ever back-to-back #1-rank victories in 2015 and 2016, and then again in 2018 and 2019. His research and educational outreach takes him to cities across the world, reaching over 10,000 people each year through public lectures and events, and he has featured in or co-created videos totaling over 15 million YouTube views.

Po-Shen received his undergraduate degree in mathematics from Caltech in 2004, graduating first in his class. He received a master’s degree in mathematics from the University of Cambridge in 2005, where he was supported by a Winston Churchill Foundation Scholarship. He continued his studies at Princeton, supported by a Hertz Foundation Fellowship and a National Science Foundation Graduate Research Fellowship, where he completed his Ph.D. in mathematics at the end of 2009, and has been on the faculty at Carnegie Mellon University ever since.
