Given the list of numbers:
2,4,7,8,12,15,19,24,34
Determine which are not multiples of 4.
Solution:
List down the multiples of 4 in roster form.
A {4, 8, 12, 16, 20, 24, 28, 32, 36, 40,…}
Put the list of numbers in roster form.
B {2,4,7,8,12,15,19,24,34}
Determine which numbers are not a multiply of 4 by applying set difference: B-A, which means that the remaining elements are elements of B that are not in A
B - A = {2, 7, 15, 19, 34}
The numbers 2, 7, 15, 19, 34 are not multiples of 4.
