Tổng trên có số số hạng là : (1000 - 2) : 2+1=500(số hạng)
Có số cặp là:500:2=250(cặp)
2+(-4)+......+998+(-1000)
=2+2+2+..+2+2
=2x250+2
Ta có: \(1996\cdot1995-996-100-1996\cdot1994\)
\(=1996\left(1995-1994\right)-1996\)
\(=1996-1996=0\)
12345x1000=12345000

I think it's gonna be like this:
5. I don't have much time so I don't use the Internet very often.
6. Tuan finds playing table tennis interesting because he often plays with his best friend.
7. I'm now having felt tired since I stayed up late to do my homework.
8. My homework will be finished by midnight.
9. We won't go anywhere until Tom comes.
10. That's one of the most interesting books I have ever read.

1996 x 1995 - 996 - 1000 - 1996 x 1994
= 1996 x 1995 - (996 - 1000) - 1996 x 1994
= 1996 (1995 -1 - 1994)
= 0
