Study Notes
Order Properties of the System (ℤ, +)
- Order properties are important for understanding mathematical operations and concepts.
- They are essential for simplifying expressions, solving equations, and ensuring consistency in calculations.
Trichotomy Property
- Statement: For any two integers,
a
andb
, one and only one of the following statements must be true:a
is less thanb
,a
is equal tob
, ora
is greater thanb
. - Proof:
- Consider the difference
d = a - b
. - If
d
is greater than zero, thena
is greater thanb
. - If
d
is equal to zero, thena
is equal tob
. - If
d
is less than zero, thena
is less thanb
. - Only one of these cases can be true because the difference
d
can only have one value.
- Consider the difference
Transitivity Property
- Statement: If
a
is less thanb
andb
is less thanc
, thena
is less thanc
. - Proof:
- Assume
a
is less thanb
andb
is less thanc
. - This means there exist positive integers
m
andn
such thatb = a + m
andc = b + n
. - Substituting
b
in the second equation, we getc = a + m + n
. - Since
m
andn
are positive,a
must be less thanc
.
- Assume
Antisymmetry Property
- Statement: If
a
is less thanb
, then it is not the case thatb
is less thana
. - Proof:
- Assume
a
is less thanb
. - This means there exists a positive integer
m
such thatb = a + m
. - Assume
b
is less thana
. - This means there exists a positive integer
n
such thata = b + n
. - Substituting
b
from the first equation into the second equation, we geta = a + m + n
, which implies0 = m + n
. - This is a contradiction because
m
andn
are positive integers. - Therefore, if
a
is less thanb
, thenb
cannot be less thana
.
- Assume
Addition Compatibility Property
- Statement: If
a
is less thanb
, thena + c
is less thanb + c
for any integerc
. - Proof:
- Assume
a
is less thanb
, so there exists a positive integerm
such thatb = a + m
. - Adding
c
to both sides, we getb + c = a + c + m
. - Since
m
is positive,a + c
is less thanb + c
.
- Assume
Multiplication Compatibility Property
- Statement: If
a
is less thanb
andc
is greater than zero, thena · c
is less thanb · c
.
