Set builder notation



A set is a collection of elements (usually numbers)

E.g. {xRxx \in 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:

- RR = real numbers

- ZZ = integers

- NN = natural numbers

- QQ = rational numbers

- CC = complex numbers

- II = imaginary numbers
