Hi I need help with Set Theory. I am in a Programming class in college and I dont understand this question at all! If you could help me, I would appreciate it.

Write three statements about sets. The first defines set A with values 1, 2, 3, 4 and 5. The second defines set B with the values 2, 4, 6, 8 and 10. The third lists the union of sets A and B. (Use the uppercase letter U to signify union.)

Thank you

Hi B-Sho;

There are lots of ways to define those sets.

A = {1,2,3,4,5}

B = {2,4,6,8,10}

Thank you bobbym!

What do you mean there are lots of ways to define those sets?

Also, is their a space between the A and U for union? is it A U B or AUB altogether?

Hi;

Either way, the space is more readable.

Other ways to define those sets are,

A is the set whose members are the first 5 positive integers.

Or you can say:

A = { n: n is an integer and n>0 and n<6 }

And there are more...

Hi B-Sho;

Do not thank me, anybody forced to do set theory is better off dead. The last time I had to do some my spleen exploded. It was not a pretty sight.

I modified post number #5.

I was the best at only one thing. It was a strange feeling. I decided I would give it up and do math instead...

Anyway, hopefully you will survive the set theory and become a good programmer.

I'm actually an Computer Information Networking Technology major "IT" For some reason they make me take a Programming class. No way in hell I could be a Programmer, I would hate my life if I did code for <=40 hours a week haha.

Hi;

Oh sorry, then you will need the set theory even less.
