The roster method is defined as a way to show the elements of a set by listing the elements inside of brackets. An example of the roster method is to write the set of numbers from 1 to 10 as {1, 2, 3, 4, 5, 6, 7, 8, 9 and 10}. An example of the roster method is to write the seasons as {summer, fall, winter and spring}.
