(9)0.25×(-2.15)+0.75×(-2.15)=______;
(10)(-4)×(-124)×(-0.25)=______.
参考答案
(1)(-14)+(+20)=6;
(2)-12-8=-20;
(3)100+(-100)=0;
(4)0+(-6)=-6.
(5)-(12)3=-18
(6)(-0.625)×(-1.6)=1
(7)(+4)×(-5)=-20
(8)(-3.25)×(+213)=-12
(9)0.25×(-2.15)+0.75×(-2.15)=-2.15;
(10)(-4)×(-124)×(-0.25)=-124.
故答案为:(1)6;(2)-20;(3)0;(4)-6;(5)-18;(6)1;(7)-20;(8)-12;(9)-2.15;(10)-124.
