Welcome to decuser's blog
Topics on this blog include computing, retro-computing, operating systems, math, and whatever other technical subjects I happen to be exploring that I find interesting enough to take and share notes about.

Algebra of sets
A note about the algebra of sets. This note informs [Boolean Algebra Notes (Jan 4, 2018)]({% post_url 2018-01-04-boolean-algebra-notes %}). The algebra of sets is a somewhat intuitive boolean algebra and it was the study of the algebra of sets that helped me better understand boolean algebra. I was introduced to the idea in NAVEDTRA, but this development is based solely on Whitesitt (1961).
