计算:1/2-(1/2-1/4)-(1/4-1/8)-...-(1/8192-1/16384).
1/2-(1/2-1/4)-(1/4-1/8)-...-(1/8192-1/16384).
=1/2-1/2+1/4-1/4+1/8-……-1/5192+1/16384
=1/16384

原式=1/2-1/2+1/4-1/4+1/8-1/8+……+1/8192-1/8192+1/16384(前面都消掉等于0)
=1/16384

原式=1/2-1/2+1/4-1/4+1/8......-1、8192+1/16384
=1/16384

1/2-(1/2-1/4)-(1/4-1/8)-…-(1/8192-1/16384)
=1/2-1/2+1/4-1/4+1/8-…-1/8192+1/16384
=1/16384
