Suppose i have three circles and i'm trying to find the shading of a, complement, union, b, and c.
00:10
Okay, c complement.
00:11
So first let's distinguish what each of these letters are.
00:14
So a complement means not in an a, everything outside of a.
00:19
Or b complement means not in b, everything outside of b.
00:22
What about the cu? you means union or what's in either set.
00:27
So i'd shade both.
00:28
And then finally the upside down you means what's in both, or i would shade what's in.
00:35
I mean or means and.
00:37
So first let's deal with this.
00:40
So not in a or in b.
00:43
Okay, maybe first let's deal with c complement.
00:46
So not in c would be everything outside of c, including if i had a larger box.
00:55
It would include everything outside of the green circle...
