I really like the top right of the bottom blackboard...

"If we think very hard about it and break the fundamentals of math, logic and everything else we know about the universe, down into the most crucial and elemental components we may be tempted to come to the conclusion that 5 is - maybe somewhat simplified - just five 1s added together, basically."

I'm sure that there's probably more going on here... maybe...

5 = 5 = 4 + 1 = 3 + 2 = 3 + 1 + 1 = 2 + 2 + 1 = 2 + 1 + 1 + 1 = 1 + 1 + 1 + 1 + 1

Riveting stuff

5 = 5
= 4 + 1
= 3 + 2
= 3 + 1 + 1
= 2 + 2 + 1
= 2 + 1 + 1 + 1
= 1 + 1 + 1 + 1 + 1

Riveting stuff

Probably how you wanted your comment to look.

Markdown doesn't recognize a new line that isn't either double (for a full paragraph break), or preceded by a double space or a \.
Markdown is a stupid design, in my opinion. Can't even write \ without actually writing \\.

I find it interesting that PieFed renders that comment correctly - there seems to be a fundamental difference in how it renders markdown.

Markdown isn’t a set standard so the rules are made up and rendering is all willy-nilly

I think the bottom one may be some sort of combinatorics

You think correctly, extremal

Not my experience as an actuarie. In college all the models and examples you learn are based on the platonic insurance company where everything works perfectly. In the real life, everything is a mess and the models hardly work and you had to crack workarounds for everything.

looks like graph theory to me

Some of it looks like topology. The curvy horizontal lines turning into curvy vertical lines are symbols relating to the Kauffman bracket, which belongs to knot theory.
