Professor Jay Jorgenson Starting with modular arithmetic. Ascii code for ≡ is 240. (Alt-240). No need Latex for this. ± is 241. ≥ is 242. ≤ is 243. And I think I'll use % for mod. Simpler.

There is a lot of sites online showing you how to find cube root of a perfect cube, provided the cubic root is less than 1000. This method requires the memorization of 10 cubes from 1 to 10. This is … Continue reading →

By Prof. Vladimir Shpilrain He walks out of class faster than we can say "Do we have syllabus?" Text: Kenneth Rosen's Discrete Mathematics and Applications Operations on sets: Symmetric difference of A and B: Non-deterministic infinite sequence: e.g. coin tosses. … Continue reading →

It would appear that the mystery of prime gap is of interest to me for the distribution of primes. It seems that there's a pattern of gaps building up. While there have been many conjectures out there pertaining to the … Continue reading →
