Answer 12

Let me find a website to help you, okay? :) My explanations may be weird.

Answer 13

Or, I will give an example.

Answer 14

There is Unions and Intersections.

Answer 15

Intersections (if I remember correctly) are where the sets share similar numbers, variables.

Answer 16

e.g; Set A {1, 2, 3, 4}
Set B {2, 4, 6}
A intersection B is {2, 4}

Answer 17

There is symbols for these.

Answer 18

That's what I think but I have gotten it wrong and they would show you the wrong one because its a quiz

Answer 19

Then, the Union ( represented by I believe greek symbol? "U" )
Which is where they each join together..
Set A {1, 2, 3, 4}
Set B {2, 4, 6}
A U B = {1, 2, 3, 4, 6}

Answer 20

Which one did you pick?

Answer 21

If I could see the symbols, that would help.
