是
因為括號部份都各自抵消掉,
所以
1000+1000-1000+1-1+1-1
=1000+(1000-1000)+(1-1)+(1-1)
=1000

1000+( 1000-1000)+(1-1)+(1-1)=1000
1000+ ( 0 )+( 0 +( 0 )+1000#
這條數非常之易,小學二年班都識啦.

1000 + 1000 = 2000
2000 - 1000 = 1000
1000 + 1 = 1001
1001 - 1 = 1000
1000 + 1 = 1001
1001 - 1 = 1000
所以 1000+1000-1000+1-1+1-1 係 等於 1000

是,
因為1000+(1000-1000)+(1-1)+(1-1)
括號部份都各自抵消掉,
所以1000+1000-1000+1-1+1-1=1000
