Read 4.1-4.4. Think about Section 4.3, Exercises 15, 18, 20, and 29;
you don't have to hand them in. In DAM2, these 15, 18, and 29
correspond to Section 4.3, Exercises 13, 16, and 24, respectively;
Exercise 43, number 20 in DAM3 doesn't exacty match anything in DAM2,
but it's somewhat similar to the other exercises. [NOTE: I CORRECTED
THE PROBLEMS THAT I SUGGESTED YOU LOOK AT.]

set up a system of congruences mod 5, 7, and 11 of which
3**302 is a solution; then find another solution. [SORRY; THIS WAS ON
LAST WEEK'S HOMEWORK; YOU DON'T HAVE TO DO IT.]
