So here we're going to find this first elements in B but not in C. This is yeah, minus elements in See Okay, so I don't want the I don't want E I don't want A F. I don't want H I sure don't want the I. Okay, so this is just going to be B. J. Okay. So next I want A without um B minus B minus C. Okay, so A contains the elements A. Mm. All right. No, I'm subtracting these two elements. Okay. So yeah, I don't need be and the cheap. So this just means I have a Mhm mm. Ah

Given Universal said you equal to a coma be coma. See human D. Goma, E. Goma, F. Comin G. And coma H. So here in part first he equal to E. Common B. Going to see we have to find the complement of said a cash equal to you negative E. The state of elements which belongs to you but not to a. Therefore complement of said A equal to de goma. E comma F. Come on G. Coma edge. So it is our answer. Now we sold part second can be equal to D. Goma, E coma F. Come on G. Goma edge. So here we have to find the complement of Sandy. So here Universal said minus B. That means the set of elements which belongs to you but not to be so you can see that complement of set be equal to e. Coma be coma. See so it is our answer. Now we sold part third were said see given e coma see Goma. E. Come on G. So here we have to find the complement of said see equal to you negative. See that means the set of elements which belongs to you but not to see. So here complement of said C. Equal to be common B. Cuomo of Goma edge. So it is a answer indeed equal to F. Go McGee coma edge, coma E. So here we have to find the complement of 30 equal to you negative B. So here compliment of the side D. Equal to be goma. See Goma de Goma. E. So it is our fire answer.

All right. We want to find the set of C. Compliment. And this just means you have your universe without C. Okay, so the universe without C. Is just equal to the so the universe. Yes, A. B. Okay minus C. Which is D. E. Mhm. Ohh. All right. Okay. So, so they I I don't want um this compliment. I don't want the anything that is in here. I do not want. Okay, so I only want a B. See I don't 80. Was this in here? Okay. Ah Yes. G. H. I. Uh I see it. So it's not as I belong here jay. Okay, so this is the universe without any element front seat.

In this problem for us to show that made it will be different. See physical, a different see difference be different seats. So I did proceed Difference be different seas of lessons. I will have element, I said, actually, an elemental a prissy and it's left me an element of be difference. See, So we can write. This one is actually an element of A and X is not an element of C friends. It's not an elemental thanks May It's not an ally to be. And it's not a moment off. See, um So, Nadia, in time here in time here and I am not in the line here, So let's just distribute those into the fantasy so we can write this on this X, um an elemental A. And it is not an element of C. And, um thanks is not an element of the or eggs is an element of sea. So we have end here and negative, um, a pregnant here, Right? So I wonder what this up writer Excellent. The Ensign Megan Or and we have nothing element here and nothing element here, So that softy got X element of seat. So let's break this oneness exist until a little, eh? And, um, not an element O c. And not an elemental be or that's an element of C and X is another little C. So we have not annulment of see here every event element of cnd have Anna Prager acting you. Dustin Wright said this part is a bull's statement. So we can just this regard this for Okay, so we're only interested in the first part right now. This is the part that is true. So be here. Eggs isn't alone. Top end. It's another element of sea and makes another element be so we can write this one as X is now a little friends that in El aumento b and, uh, nothing element. See, sir, this is basically, um, same thing as saying a defense. Be difference. See, So we have from this part it's an elemental a visit. PNC here and not annulment would be so that it's a defense, Pete. And this is not an element of seats. So that is these different. See
