Answer:
Option (3)
Explanation:
Integers are the numbers which don't have a fractional part (having positive of negative notations)
Example; -2, -1, 0, 1, 2,...
Let the two integers are 0 and 2,
Subtraction of these integers will be = 0 - 2
= 0 + (-2)
Here opposite of 2 has been added to 0.
That means subtraction of two integers is to add the opposite of the integer being subtracted.
Option (3) will be the answer.
