1) 1997 x 1996 - 1/1995 x 1997 + 1996
= 3986011/3986011
= 1
2) 1996 x 1995 + 1994/1995 x 1997 - 1
= 3984014/3984014
= 1
3) 1997 x 1996 - 995/1995 x 1997 + 1002
= 3985017/3985017
= 1
4) 7/11 + 3/4 + 4/11 + 1/4
= (7/11 + 4/11) + (3/4 + 1/4)
= 11/11 + 4/4
= 1 + 1
= 2
5) 1996 x 1995 - 996/1000 + 1996 x 1994
= 3981024/3981024
= 1
