RULE METHOD-elements are descreted
ex: B={red,orange,yellow,green,blue,indigo,violet}
B={xlx is the set of all colors of the rainbow}
E={1,2,3,4...100}
E={xlx is the set of all counting numbers up to 100}
is a method that have a rule
The rule method specifies a set of by describing its elements and enclosing them in braces.
1) listing method: { 1,2,3} rule method: {x| x is a positive whole number less than four} 2) listing method: { 2,4,6,8,....}. rule method: {x| x is a positive even number }
A={x/x is factor of 12
rule method - writing a common property/a descriptive phrase, and agreeing that those objects, and only those are elments of the sets. ex. rule method X= X is an even number between 25 and 40. roster method X= {26,28,30,32,34,36,38}

A single number, such as 1368, is not sufficient to determine a rule.
A={x/x is factor of 12
rule method - writing a common property/a descriptive phrase, and agreeing that those objects, and only those are elments of the sets. ex. rule method X= X is an even number between 25 and 40. roster method X= {26,28,30,32,34,36,38}
