Question

Example of a union in math

Answer 1

1) If we think of sets, let A ={1,3,5,7} and B={2,4,6,8, 7} when we want to express that the union of elements of both A and B we can write:

A∪B ={1,2,3,4,5,6,7,8}

2) Note that repeated elements, in this case, 7 are no supposed to be enlisted twice since it is the same element.

A∪B the union of both sets, in a diagram.
