Some random maths stuff

Systems of equations

$\begin{cases} x + y &= z \\ z + x &= y \end{cases}$

$\begin{cases} a + b &= c \\ c + d &= e \\ e + f &= g \end{cases}$

Sets

• Let's keep it $\mathbb R$
• If you like headaches $\mathbb C$
• "Au naturel" $\mathbb N$
• Everything is relative $\mathbb Z$
• Existential dread be like: $\lbrace \overrightarrow{0_{\mathbb R}} \rbrace$
