2.5-2.8 and 3.8, due on September 16

• The most difficult part of this text was to understand how all the ciphers worked. It took reading through and through again and again to understand, even a little bit, how they fit together. I tried on my own before they solved it for me, and it was definitely difficult.
• The coolest part of the text was when we started using matrices and mathematics to create and solve ciphers. I took linear algebra and LOVED it, so using matrices to solve ciphers kind of came naturally to me. I really enjoyed the parts of the text about mathematics.
