9.99*22.2+33.3*3.34=(33.3×0.3)×22.2+33.3×3.34=33.3×(0.3×22.2)+33.3×3.34=33.3×6.66+33.3×3.34=33.3×（6.
6.25*8.37*16+3.75*0.837*8=1.25*5*8.37*8*2+1.25*3*0.875*8=(1.25*8)*（2*5）*8.75+（1.25*8）*3*0.875=10*10*
3.34×3.33+2.22×9.99=3.34×3.33+2.22×3×3.33=3.34×3.33+6.66×3.33=（3.34+6.66)×3.33=10×3.33=33.3
9.99*2.22+3.33*3.34=3.33*3*2.22+3.33*3.34=3.33*(6.66+3.34)=3.33*10=33.3
9.99*2.22+3.33*3.34=3.33*6.66+3.33*3.34=3.33*(6.66+3.64)=3.33*10=33.3
原式=33.3*6.6633.3*3.34=33.3*10=333
（7.25+3.75）-（6.66+3.34）
=2.46+0.246-1.71=2.706-1.71=0.996=8.37*(8+0.2+1.8)=8.37*10=83.7
8.37*(1.2-0.2)
6.25*8.37*16+3.75*0.837*8=1.25*5*8.37*8*2+1.25*3*0.875*8=(1.25*8)*（2*5）*8.75+（1.25*8）*3*0.875=10*10*
=17.8-（1.63+8.37）=17.8-10=7.8
3.34*8.37-3.34*5.37-3.34=3.34*（8.37-5.37-1）=3.34*2=6.68
