Set builder notation
Lessons
A set is a collection of elements (usually numbers)
E.g. {x∈R∣x > 0} should be read as "the set of all x's that are an element of the real numbers such that x is greater than 0."
Special symbols:
- R = real numbers
- Z = integers
- N = natural numbers
- Q = rational numbers
- C = complex numbers
- I = imaginary numbers
