0Integer (Z)= ...-3,-2,-1,0,1,2 3,4...
A.If you add two integers you will get ineger
Like 4 + 5 = 9
Integer+integer=integer
So , you can say integers are closed under addition.
B. If you subtract two integers you will get integer
Like 6 - 4 = 2
Integer - integer = integer
So, you can say integers are closed under subtraction
C. If you multiply two integers you will get integer
Like 5 x 4 = 20
Integer x integer = integer
So , you can say integers are closed under multiplication
D. Integers are not closed under division
Like 5÷2= 2.5
2.5 is not integer
Integer ÷ integer is not equal integer
So, you can say integers are not closed under division
