Sets
A set is a collection of objects. The objects in the sets are
called elements members
or .
Proper notation requires the set's elements to be separated by
commas and enclosed in a pair of braces { }.
E.g. A set which contains the days of the week can be represented
as:
{Monday , Tuesday , Wednesday , Thursday , Friday , Saturday , Sunday }.
E.g. Set A which contains elements two, four, six and eight can be
represented as:
A = {2, 4, 6, 8}.

Venn Diagrams
A Venn diagram (also called primary diagram, set diagram or
logic diagram) is a diagram that shows all possible logical
relations between a nite collection of dierent sets.
E.g.
For U ={1,2,3,4,5,6}:
(a) A={1,2} B ={3,4,5}
(b) A={1,2,3} B ={3,4,5} Note: A ∩ B ={3}
(c) A={1,2} B ={1,2,3,4,5} Note: A ⊂ B

The Set of Complex Numbers
A complex number is a number of the form a + i b where a and b
are real numbers and i 2 = −1 where a is referred to as the real part
and b as the imaginary part.
C = {a + i b; a, b ∈ R; i 2 = −1}
If a = 0 the number is wholly imaginary. e.g. 2i, −4i
If b = 0 the number is real. e.g. 5, −1
If a complex number is 0, both a and b are 0.
