Proove: the sum of two even numbers is even
$E:= \{m: 2m, m \in \mathbb{N}\}$
$U:= \{n: 2n+1, n \in \mathbb{N}\}$
Proof by contradiction:
assume $E_1+E_2=U$
$\Rightarrow 2m_1+2m_2=2... | 4 | [

Euler's formula + Handshake Theorem
Using Euler's formula and the Handshake Theorem, how can I show that this graph is non-planar?
The number of vertices is 8 The number of edges is 14 The number of faces is f Then, 8-14+f=2 if planar. Thus, f=8 Which is not true. I did it this way because I was too lazy counting all ... | 4 | [
