8.88x0.15+265x0.0888+5.2x8.88+0.888x20的简便算法
8.88x0.15+265x0.0888+5.2x8.88+0.888x20
=0.888x1.5+26.5x0.888+52x0.888+0.888x20
=0.888×（1.5+26.5+52+20）
=0.888×100
=88.8
8.88x0.15+2.65x8.88+5.2x8.88+2x8.88=8.88x(0.15+2.65+5.2+2)=8.88x10=88.8
8.88×0.15 265×0.0888 5.2×8.88 0.888×20 =8.88×0.15 8.88×2.65 8.88×5.2 8.88×2 =8.88×(0.15 2.65 5.2 2) =8.
