Types of Sets
n(S) = number of distinct elements in set S
Subsets and Supersets
A ⊂ B if a ∈ A ⟹ a ∈ B
A ⊂ B and B ⊂ A ⟺ A = B
Number of subsets of a set with n elements = 2ⁿ
Number of proper subsets = 2ⁿ - 1
Intervals as Subsets of R
(a, b) = {x : a < x < b}
[a, b] = {x : a ≤ x ≤ b}
[a, b) = {x : a ≤ x < b}
(a, b] = {x : a < x ≤ b}
Length of interval = b - a
