I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

Hmm, okay I see. I just don't understand why my teacher said that you can't use laws when doing a proof by subsets. And even after she said that, she did an example proof by subset using laws! I understand, now. Thank you, Ross, for your help.

Okay, but if I was to strictly do a proof by subsets, I would just suppose $x \in~thing_1$, and describe how $x$ being in $thing_1$ also describes $x$ being in $thing_2$, and not use any sort of laws?

Okay, I see. That's pretty much what I understood the process to be. Just to be clear, I am allowed to use laws (such as De Morgan's) while proving either side is a subset of the other?

@lamb_da_calculus All right, that's pretty much what I understood the process to be. Just to be clear, I am allowed to use laws (such as De Morgan's) while proving either side is a subset of the other?

I'm sorry, I didn't mean proof using subsets, I meant to say proof by subsets. Here is an example problem: Show that if $A$, $B$, and $C$ are sets, then $(A∩B∩C)^c= A^c∪B^c∪C^c$. And I am asked to prove that these are subsets of each other, thus proving that they are equivalent.
