6.66*9.37+2.22*61.37+4.44*5.26的简便算法
6.66*9.37+2.22*61.37+4.44*5.26的简便算法
6.66*9.37+2.22*61.37+4.44*5.26的简便算法
6.66*9.37+2.22*61.37+4.44*5.26
=2.22*28.11+2.22*61.37+2.22*10.52
=2.22*（28.11+61.37+10.52）
=2.22*100
=222
6.66*9.37+2.22*61.37+4.44*5.26
=2.22*28.11+2.22*61.37+2.22*10.52
=2.22*(28.11+61.37+10.52)
=2.22*100
=222
6.66*9.37+2.22*61.37+4.44*5.26
=1.11×6×9.37+1.11×2×61.37+1.11×4×5.26
=1.11×（6×9.37+2×61.37+4×5.26）
=1.11×200
=222
