Detailed Solution

It is given that a negative integer is subtracted from another negative integer.
Case 1, Let us consider two negative integers -4 and -5 Subtracting one negative integer from another.
-4--5
=-4+5

Here, the difference of two negative numbers gives a positive integer.
Case 2, Now, let us consider two negative integers -3 and -2.
Subtracting one negative integer from another.
 -3-(-2)
=-3+2
=-1
