1.1 The Real Number System - UH
www.math.uh.eduAn integer is odd if it can be written in the form 2n −1, where n is an integer (if 2 is not a factor). Example: 2, 0, 8, -24 are even integers and 1, 57, -13 are odd integers. 4. The rational numbers are the numbers that can be written as the ratio of two integers. All

Chapter 3, Rings
www.math.hawaii.eduThe set of odd integers is not a ring. We can also work with matrices whose elements come from any ring we know about, such as Mn(Zr). Example. Let R = M2(Z2). This is a nite (16 elements) noncommutative ring with identity 1R = 10 01 and zero element 0R = 00 00 . We give an example to show it is noncommutative: 10 00 01 00 = 01 00

www.math.uh.edu(i) Let the universal set be the integers. Then the compliment of the even integers is the odd inte-gers. (ii) Let the universal set be {1,2,3,4,5}, then the compliment of S = {1,2,3} is Sc = {4,5} while the compliment of T = {1,3,5} is Tc = {2,4}. (iii) Let the universal set be the letters {a,e,i,o,u,y}. Then {y}c = {a,e,i,o,u}. The Venn ...
