SAT Math Lesson 12 - Factors, Multiples, ...

Yeah baby! Lesson 12! I had to work OT to get this up, so I hope you are as amped about it as I am! I review Elementary Number Theory, which is a fancy way of saying I do problems related to factors, multiples, prime #s and remainders. Out of the blue book, I work out: p463 #15, p489 #7, p549 #7, and p596 #8.
