Here is the problem that I want to make sure I have an understanding of:

(A intersects B) - C

Given the following sets: A= {1,4,7,10} B= {1,2,3,4,5} C= {2,4,6,8}

Order of operations tells me to do what's in parentheses first. A intersecting B which gives me {1, 4}

Now minus C is where I'm a little fuzzy - I think the final answer is {4} because I took out the number that wasn't in set C - being 1.

Am I on the right track?
