2.5-2.8, due on September 10

DIFFICULT
I just don't understand the example in section 2.6: 100 is even if and only if 101 is prime, and why it is true.  I found that using a truth table makes these statements quite easy, so maybe when I delve into the next assignment, and after lecture tomorrow, I'll understand it better.

REFLECTIVE
Section 2.5 is just like section 2.4, and I understood section 2.4 more fully after the class discussion on September 8.  Section 2.7 was quite intuitive.  The gospel is a tautology, it is always true no matter the combination and never a contradiction.  We talked about logical equivalence briefly on September 8, and it seemed intuitive, after reading section 2.8 it also seemed intuitive.
