就这样直接算,先计算括号里面的268-(72+28)=268-100=168

38Ⅹ29十28=(10+28)x29+28=10x29+28x29+28=290+28x(29+1)=290+28x30=290+840=1130

105*28=105*4*7=420*7=2940

196-2x=28 2x=168 x=84

1535一35x28=1535-980=555

解:[196一(96十4)]/6 =[196一100]/6 =96/6 =16X6/6 =16

11*8*9 =28*11.99*8 =28*11.11+1128*11.11+11.11*72 =(28+72)*11.11+99
