Here's the question you clicked on:

f A = {2, 4, 6, 8, 10, 12, 14} and B = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, what is A B? { } {1, 2, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9, 10, 10, 12, 14} {2, 4, 6, 8, 10} {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14}
what symbol is between A and B
what does U mean in this context?
U means union i assume. so basically add the values in each set to eachother so. {2, 4, 6, 8, 10, 12, 14,1, 2, 3, 4, 5, 6, 7, 8, 9, 10} except sort it numerically
