My name is Deyan Kassev, and I am a high school student from the United States. For as long as I can remember, I have been fascinated with mathematics. I have participated in countless math competitions including Math Olympiad, AMC 8 and 10, Mathcounts, and various regional math leagues. I have also tutored aspiring middle school mathletes. Through my videos, I hope to share my knowledge of mathematics and help students prepare for competition math, Algebra II, and statistics.
