Question

is integers are closed under subtraction?justify your answer by taking two examples​

Answer 1

Answer:

Yes. Subtracting one integer from the other gives you another integer. i.e., Difference of two integers is obviously an integer again.

Step-by-step explanation:

eg.1) -4-7=-11, which is an integer.

eg.2) 9-(-3)=12, which is an integer.

eg.3) 6-2=4, which is an integer.

eg.4) -3-(-5)=2, which is an integer.

So the set of all integers is closed under subtraction.

However the set of "Positive integers" are not closed under subtraction. The same applies for the set of "Negative integers" also.
