Answer by HyperBrain(694)   (Show Source):
You can put this solution on YOUR website! {a,b,c} U {a,c}={a,b,c}
Union of sets is the set of ALL elements that belong to those sets.
You might think that union is combination.And, that I could write:
{a,b,c} U {a,c}={a,b,c,a,c}
The problem with this is that a, and c are repeated. this is also correct, but it is not the conventional way. A set is commonly written with distinct elements.
Power up,
