(1)(+4.3)-(-4)+(-2.3)-(+4);
(2)-4-2×32+(-2×32);
(3)(-48)÷-(-25)×(-4)+.
(1)(+4.3)-(-4)+(-2.3)-(+4);
(2)-4-2×32+(-2×32);
(3)(-48)÷-(-25)×(-4)+.
(1)2 (2)-132 (3)-90
解:(1)(+4.3)-(-4)+(-2.3)-(+4)=4.3+4-2.3-4=2.
(2)-4-2×32+(-2×32)=-4-64-64=-132.
(3)(-48)÷-(-25)×(-4)+=6-100+4=-90.
(2)-4-2×32+(-2×32)=-4-64-64=-132.
(3)(-48)÷-(-25)×(-4)+=6-100+4=-90.
