{\large {\bf  Homework 2.8b: Prime Proof and  Emails  
}}
\end{center}
 
\noindent
1. Study Euclid's proof of the infinitude of prime numbers until you understand it. Then, write out the proof in your own words. Look at each step, see if you understand it, and then write that step out in your own words. If you get stuck, look back at the step again, then put it aside, and try to write it out again. 

\noindent
2. Write me an email at erasmuse61@gmail.com. 

\noindent
3. Write me a letter and mail it to me by U.S. Mail, snailmail. My address is: 2810 Dale Court, Bloomington, Indiana 47401.  I did not say this in class, but now I will tell you: mail me problem (1), your write-up of Euclid's proof.
