A=0.00........0(2000个)0125
B=0.00...0(2004个)08=0.00...0(2000个)000008
A+B=0.00...0(2000个)012508
A-B=0.00...0(2000个)012492
不妨这样算
A=0.00........0(2000个)0125
B=0.00...0(2004个)08=0.00...0(2000个)000008
A+B=0.00...0(2000个)012508
A-B=0.00...0(2000个)012492
这样子很简单就出来了
但愿能帮到你
望采纳
A+B=0.00...0(2000ge0)012508
A-B=0.00...0(2000ge0)012492
