is integers associative under subtraction? explain with suitable examples.

No integers are not associative under subtraction.
 Ex-a-(b-c)is not equal to (a-b)-c
 Let a=2,b=3 and c=4
L.H.S=2-(3-4)
        =2-(-1)
       =2+1
      =3

R.H.S=(2-3)-4
         =-1-4
        =-5
Therefore L.H.S is not equal to R.H.S.
Therefore a-(b-c) is not equal to (a-b)-c,that implies that integers are not closed under subtraction.
