答案
(1)-32-(-2)2-9-4 =-13; (2)-14-
=-1-
=-1+
=
(3)(-10)2+[(-4)2-(3+32)×2] =100+(16-24) =92; (4)(-1)4-(1-0.5)×
=1-
=1
(5)-0.52+
=-0.25+
=-6.5; (6)(-2)3-3×[(-4)2+2]-(-3)2÷(-2) =(-8)-3×18+
=(-8)-54+
=-62+
=-
(7)(-2)2003+(-2)2002 =-22003+22002 =-22002×2+22002 =22002×(-2+1) =-22002; (8)(-0.25)2009×42008 =-(
