Parts and what they mean

• A ⊂ B (A ⊂ B) — Every element of A is also in B, so circle A lies completely inside circle B.
• Set B (समुच्चय B) — B is the bigger set (superset of A).
• Universal set U (सार्वत्रिक समुच्चय U) — The rectangle: all the elements under discussion. Every set here is a subset of U.
• Disjoint sets (असंयुक्त समुच्चय) — A and B have no common element: A ∩ B = φ, so the circles do not overlap.
