EXAMPLE 2. 11 consists of the three symbols 0, , and L. Two binary operations (>) and (<) are defined on M by the following "multiplication" tables. To read the first table, for example, a > b is found in the table in the row opposite a and in the column below b, where a and b may be any of the three symbols in AT. Thus > 0 = O, and L < O = O. A O O O D El O C O O o 11 0 0 Among the familiar binary operations, many satisfy certain simple identities, or laws, familiar from elementary algebra as well as from Chapter 1.
