    Start with set A A= {All even integers from 2 to 20, inclusive} and expand it out to get A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} Now erase any number in the set above that you also find in set B.

    you start with A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} then you erase everything the elements in that set above that are also in B. So you erase 10, 12, 14, 16, 18 to get B' = {2, 4, 6, 8, 20}

    set nickels = {collection of all nickels} universal set is {pennies, nickels, dimes, quarters} So start with {pennies, nickels, dimes, quarters} and kick out all the nickels to find the complement of the set of nickels
