Symbols save time and space when writing. Here are the most common set symbols. In the examples C = {1, 2, 3, 4} and D = {3, 4, 5} but B has more elements. { n | n > 0 } = {1, 2, 3,...} { n : n > 0 } = {1, 2, 3,...} {1, 2, 3,...} or {0, 1, 2, 3,...} {..., −3, −2, −1, 0, 1, 2, 3, ...}

We use the ∈ symbol to indicate that some object belongs to some set. With that said, let's switch to talking about this symbol for a while. Before we talk about it, look at your notes and see what this symbol means. If you don't remember, quickly jump back to the lecture slides to get the answer.
Definitive list of the most notable math symbols in set theory — categorized by function into tables along with each symbol's meaning and example.

We need to show that \[A \cup (B \cap C) \subseteq (A \cup B) \cap (A \cup C), \qquad\mbox{and}\qquad (A \cup B) \cap (A \cup C) \subseteq A \cup (B \cap C).\] Here is a proof of the distributive law \(A \cup (B \cap C) = (A \cup B) \cap (A \cup C)\).
If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y. If x≫y, x is much greater than y. If x≤y, x is less than or equal to y. If x≥y, x is greater than or equal to y.
By the "union", what it basically means that: $$ a \in \bigcup_{\alpha} A_\alpha \iff \exists \alpha :a \in A_\alpha $$ or in words - it is the set of elements which are contained in any of the $A_\alpha$.
