In the Brilliant app it just introduces this simplification method (of multiplying?) out of the blue, without explaining it or introducing the concept. What is this called and where can I learn about it?

This is finding a common denominator. The common denominator is 30 (simply just multiply the denominators). x/6 = 5x/30 and x/5 = 6x/30.
x/5 - x/6 = 6x/30 - 5x/30 = (6x - 5x)/30 = x/30

How did Euler do all the wonderful things he did without a today's technology? Or did he just do all of the wonderful things because he was so ahead of his time?

In the book "Hyperspace" by Michio Kaku, Kaku discusses Bernhard Riemann, number Theory, and Adrien-Marie Legendre and his book "Theory of Numbers". Does anyone know where I can find this book, or perhaps have a copy?
