>p is a prime in a ring R That reminds of the topic of groups, rings and fields that I had in either last year of high school or an early year of college (Math.). I thought that was a really cool topic. Not too hard (for the stuff we covered), and still some cool results/theorems in it. Also, they underlie a lot of other areas of mathematics. https://en.wikipedia.org/wiki/Group_(mathematics) https://en.wikipedia.org/wiki/Group_(mathematics) https://en.wikipedia.org/wiki/Ring_(mathematics) https://en.wikipedia.org/wiki/Ring_(mathematics) https://en.wikipedia.org/wiki/Field_(mathematics) https://en.wikipedia.org/wiki/Field_(mathematics)
