Hey guys,
So in a universal set that $\displaystyle x$ are all natural numbers and $\displaystyle x \le 12$
does $\displaystyle C = \{ x | 3|x \}$ mean all positive integers divisible by 3?
So in this case it would be 3, 6, 9, 12 ?
thanks!

thanks for that idea and reply.
Also if:
in a universal set that are all natural numbers and ,
$\displaystyle A= \{ 3,4,5,6,7,8,9,10 \}$
$\displaystyle B = \{ 9, 10, 11 \}$
$\displaystyle C = \{ 3,6,9,12 \}$
whats $\displaystyle (A\cup \overline{B}) \cap C =$ ?
Would I start with the brackets $\displaystyle (A\cup \overline{B})$ then get that result and work out $\displaystyle [RESULT] \cap C$ ? Also i cant figure out $\displaystyle \overline{B} $ from the B set... any help? thank you!
That is correct if your text material does not include 0 as a natural number.
