=(10-0.01)*2.22+3.33*(3.33+0.01)
=10*2.22-0.01*2.22+3.33*3.33+3.33*0.01
=10*2.22+0.01*（3.33-2.22）+3.33*3.33
=10*2.22+0.01*1.11+3.33*3.33
=10*1.11*2+0.01*1.11+1.11*1.11*9
=1.11*（10*2+0.01+9*1.11）
=1.11*30
=33.3本回答被网友采纳
=10*2.22-0.01*2.22+3.33*3.33+3.33*0.01
=10*2.22+0.01*（3.33-2.22）+3.33*3.33

原式=3.33×(3×2.22)+3.33×3.34
=3.33×6.66+3.33×3.34
=3.33×(6.66+3.34)
=3.33×10
=33.3
=3.33×6.66+3.33×3.34
=3.33×(6.66+3.34)
=3.33×10
=33.3
