Chapter 8, Problem 3

(choose chapter or problem)

The congruence modulo 3 relation, T , is defined from Z to Z as follows: For all integers m and n,

m T n \(\Leftrightarrow\) 3 | (m  n).

a. Is 10 T 1? Is 1 T 10? Is (2, 2) \(\in\) T? Is (8, 1) \(\in\) T ?

b. List five integers n such that n T 0.

c. List five integers n such that n T 1.

d. List five integers n such that n T 2.

e. Make and prove a conjecture about which integers are related by T to 0, which integers are related by T to 1, and which integers are related by T to 2.
