integer:
- natural numbers (positive
integers);
- zero;

- negative integers
...


Real Numbers:
- rational numbers;
- irrational numbers
...

Historically originated in
the search for solutions to
the equation:

x  1
...


An imaginary unit is an
expression:

i  1
with the main property:

i  1
...

3

The sum of a real number
with an imaginary is called
a complex number, for
example:

1 6i,

 4  i
...


For example, the irrational
number e can be considered
complex, because:

e  e  i0
...


If the real part of the complex
number is zero, then
pure
z  0  ib  ib  imaginary
number
...


A complex number is zero if
the real and imaginary parts
are zero
...


The complex number

z  a  ib
can be represented on the
OXY plane as a point M(a;b),
whose coordinates are real
and imaginary parts
...
