divide by 0
Hey guys, I'm first year college and I need help.
How? ∪ = UnionCode:Sets: E = {x|x is an event integer} F = {x|x is an odd integer} Give the elements: E ∪ F
Thanks

Ω this is the hard symbol and powerful in mathematics
x|x is referring to two different integers, I believe... so:
E = {2, 4}
F = {1, 5}
E U F = {1,2,4,5}

E= {2, 4, 6, 8....} it is read as E is X such that X is an even integer (I am assuming it is a whole number as well, just in case).
F= {1, 3, 5, 7....} it is read as E is X such that X is an odd integer (I am assuming it is a whole number as well, just in case).
The union of two sets is the addition of all their elements.
Whereas, the intersection is only the common elements.
So, E U F= {1,2,3,4,5,6...∞}
However, E ∩ F= {∅}
