PreTeXt Sample Book Abstract Algebra (SAMPLE ONLY)

Suppose \(n\) is even.
🔗

---
Then there exists an \(m\) so that \(n = 2m\text{.}\)
🔗

---
Then \(n\) is a prime number.
🔗
 #paired
---
Then there exists an \(m\) so that \(n = 2m + 1\text{.}\)
🔗
 #paired
---
Click the heels of your ruby slippers together three times.
🔗
 #distractor
---
So \(n = 2m + 0\text{.}\)
🔗
 
This is a superfluous second paragraph in this block.
🔗

---
Thus \(n\equiv 0\mod 2\text{.}\)
🔗

And a little bit of irrelevant multi-line math

\begin{align*}
c^2&a^2+b^2\\
&x^2+y^2\text{.}
\end{align*}
