Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of .
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.

Given:
Addition and subtraction of integers.
To find:
The value of each expression.
Solution:
We know that,
Adding Integers :
1) 85+ (-96) = 85 - 96 = -11
2) 80 + 57 = 137
3) 86 + (-38) = 86 - 38 = 48
4) 22 + (-41) = 22 - 41 = -19
5) -18 + (-45) = -18 - 45 = -63
6) -32 + 48 = 16
7) 6+ (-33) = 6 - 33 = -27
8) 6 + (-47) = 6 - 47 = -41
9) (-78) + 69 = -78 + 69 = -9
10) -72 + (-30) + 10 = -72 - 30 + 10
= -102 + 10
= -92
11) -83 + (-36) + 20 = -83 - 36 + 20
= -119 + 20
= -99
Subtracting Integers :
1) 1-3 = -2
2) 2-(-5) = 2 + 5 = 7
3) 6-(-9) = 6 +9 =15
4) -7 - (-1) = -7 + 1 = -6
5) -7 - 4 = -11
6) 3- (-2) = 3 + 2 = 5
7) 1-9 = -8
8) 2-9 = -7
9) -8 - (-1) = -8 + 1 = -7
