Geometry notation: what does $m\\angle ABC$ mean?
∠ABC refers to the physical angle itself while m∠ABC refers to its measure. There isn't any difference between these two and it is absolutely correct to use any of them...Some people just want to formalize things; these people think-"I have a car that is priced at 50000dollars, so i am driving a car and not 50000dollars" and so want to differentiate between little everything.

Is zero odd or even? - Mathematics Stack Exchange
2020年12月12日 · Yes, the classification of naturals by their parity (= remainder modulo $2)$ extends naturally to all integers: even integers are those integers divisible by $ 2,\,$ i.e. $\rm\: n = 2k\equiv 0\pmod{\! 2},\,$ and $ $ odd integers are those with remainder $1$ when divided by $2,\ $ i.e. $\rm\ n = 2k\!+\! 1\equiv 1\pmod{\! 2}.\,$

Proving that a Euler Circuit has a even degree for every vertex
Proof: If G is Eulerian then there is an Euler circuit, P, in G. Every time a vertex is listed, that accounts for two edges adjacent to that vertex, the one before it in the list and the one after it in the list.
