WHOLE
NUMBERS
:
The
set
of
integers
is
comprised
of
natural
numbers
and
their
opposites
,
it
ie
positive
numbers
and
their
opposites
that
are
negative
.
Example
:
The
set
of
integers
is
defined
as
follows
:
Z
+
=
Positive
integers
Z
=
negative
integers
(
0
=
neutral
element
,
zero
is
neither
positive
nor
negative
)
ABSOLUTE
VALUE
:
If
a
number
is
positive
,
the
absolute
value
is
the
same
number
and
if
it
is
negative
its
absolute
value
is
the
opposite
.
The
absolute
value
is
never
negative
.
Example
:
-
3
=
3
reads
:
absolute
value
of
minus
three
three
5
=
5
reads
:
absolute
value

Operations

:
SUM
:
The
sum
of
integers
is
divided
into
:
SUM
OF
____________________
integers
:
The
sum
of
____________________
positive
____________________
is
performed
in
the
same
way
that
two
natural
numbers
are
added
.
WHOLE
SUM
OF
NEGATIVE
:
The
sum
of
two
negative
integers
is
obtained
by
adding
the
absolute
values
?
?
of
the
____________________
and
putting
a
negative
sign
to
the
result
.
Procedure
:
to
.
We
place
the
numbers
to
be
added
in
parenthesis
b
.
We
add
their
____________________
values
c
.
The
result
will
put
a

SUM
OF
WHOLE
WITH
DIFFERENT
SIGNS
:
The
sum
of
two
integers
of
different
signs
is
obtained
by
subtracting
the
absolute
value
greater
whole
,
the
entire
lower
absolute
value
.
in
the
result
the
sign
of
integer
greater
absolute
value
is
written

Operation
to
be
performed
We
add
negative
integers
and
the
result
we
add
its
absolute
value
.
We
add
the
positive
integers
and
its
outcome
will
find
absolute
value
.
We
subtract
these
two
results
and
let
the
result
the
sign
of
the
larger
number
having
greater
absolute
value
.
PROPERTIES

THE
ADDITION
OF
WHOLE
NUMBERS
Clausurativa
:
The
sum
of
two
integers
gives
results
in
another
integer
.
Commutative
:
The
order
of
the
addends
does
not
change
the
result
.
Associative
:
When
you
add
more
than
two
integers
,
how
are
grouped
does
not
change
the
result
.
Modulativa
:
Adding
any
integer
zero
,
the
result
is
the

is
the

is
the

Since
a

operation
is

gives
the

performed
as
follows
:
When
we
add

multiplication
with
respect
to
addition
:
The
product
of
a

DIVISION
:
In
integer
division
may
be
the
case
that
both
numbers
are
positive
,
negative
or
both
are
having
different
sign
.
Considering
the
above
possibilities
can
draw
the
following
conclusions
:
1
.
The
quotient
of
two
positive
integers
is
a
positive
integer
(
15
)
/
(
3
)
=
5
2
.
The
negative
quotient
of
two
integers
is
a
positive
integer
(
-
24
)
/
(
-
6
)
=
4
3
.
The
ratio
of
the
division
of
two
integers
different
sign
is
a
negative
integer
.
(

In
