Euler's Totient Theorem and Fermat's Little Theorem - Modular Arithmetic

In this video I will be going over Euler's (pronounced oiler although I said yooler in the video) totient theorem and Fermat's Little Theorem. I mispronounced some words (including euler) but hopefully the video is still helpful. Also, If you do know if a and n should be relatively prime, please leave a comment down below. Enjoy!
