Based on the equations provided, we can sort them out according to the properties they illustrate:
Commutative property:
-7 . 1 = -7 (Multiplication is commutative)
99+0=99 (Addition is commutative)
0.4 + 2.3 = 2.3 + 0.4 (Addition is commutative)
Identity property:
99+0=99 (Addition has an identity element of 0)
4 . 11 = 44 (Multiplication has an identity element of 1)
Associative property:
3 + (7+19) = (3+7)+19 (Addition is associative)
2 (4 . 11) = 2 (4 . 11) (Multiplication is associative)
Not a property:
8 . 7 . 6 = 8 7 6 (This equation does not demonstrate any specific property. It is simply a mathematical equation without any inherent property being illustrated.)
In summary:
Commutative property: -7 . 1 = -7, 99+0=99, 0.4 + 2.3 = 2.3 + 0.4
Identity property: 99+0=99, 4 . 11 = 44
Associative property: 3 + (7+19) = (3+7)+19, 2 (4 . 11) = 2 (4 . 11)
Not a property: 8 . 7 . 6 = 8 7 6

-7 . 1 = -7
3 + (7+19) = (3+7)+19
8 . 7 . 6 = 8 7 6
99+0=99
2 (4 . 11) = 2 (4 . 11)
5-3-=3-5
1 (-99) = 99
0.4 + 2.3 = 2.3 + 0.4
which of these are not a property, commutive, identity, and associative

What about 5-3=3-5 and 1 (-99) = 99
Apologies for the oversight. Let's include those equations in the correct categories:
Commutative property:
-7 . 1 = -7 (Multiplication is commutative)
99+0=99 (Addition is commutative)
0.4 + 2.3 = 2.3 + 0.4 (Addition is commutative)
5-3=3-5 (Subtraction is commutative)
Identity property:
99+0=99 (Addition has an identity element of 0)
4 . 11 = 44 (Multiplication has an identity element of 1)
Associative property:
3 + (7+19) = (3+7)+19 (Addition is associative)
2 (4 . 11) = 2 (4 . 11) (Multiplication is associative)
Not a property:
8 . 7 . 6 = 8 7 6
Corrected summary:
Commutative property: -7 . 1 = -7, 99+0=99, 0.4 + 2.3 = 2.3 + 0.4, 5-3=3-5
Identity property: 99+0=99, 4 . 11 = 44
Associative property: 3 + (7+19) = (3+7)+19, 2 (4 . 11) = 2 (4 . 11)
Not a property: 8 . 7 . 6 = 8 7 6
Commutative property:
-7 . 1 = -7 (Multiplication is commutative)
99+0=99 (Addition is commutative)
0.4 + 2.3 = 2.3 + 0.4 (Addition is commutative)
5-3=3-5 (Subtraction is commutative)
Identity property:
99+0=99 (Addition has an identity element of 0)
4 . 11 = 44 (Multiplication has an identity element of 1)
Associative property:
3 + (7+19) = (3+7)+19 (Addition is associative)
2 (4 . 11) = 2 (4 . 11) (Multiplication is associative)
Not a property:
8 . 7 . 6 = 8 7 6
Corrected summary:
Commutative property: -7 . 1 = -7, 99+0=99, 0.4 + 2.3 = 2.3 + 0.4, 5-3=3-5
Identity property: 99+0=99, 4 . 11 = 44
Associative property: 3 + (7+19) = (3+7)+19, 2 (4 . 11) = 2 (4 . 11)
Not a property: 8 . 7 . 6 = 8 7 6
