999.9+99.9+9.9+0.9
=1000-1+0.9+100-1+0.9+10-1+0.9+0.9
=1110-3+0.9×4
=1110-3+3.6
=1110.6
6.92－8/11－3/11+3.18
=6.92－（8/11+3/11）+3.18
=6.92+3.18-1
=10-1
=9
497-97×3+37
=400+97-97×3+37
=400+97×（1-3）+37
=400-97×2+37
=400-194+37
=206+37
=243

=4+30-14
=12
九分之四×[0.75－（十六分之七－0.25）]
=九分之四×[0.75－十六分之七+0.25]
=九分之四×[1－十六分之七]
=4/9×9/16

=1.32×5/8+2.68÷8/5
=1.32×5/8+2.68×5/8
=5/8×（1.32+2.68）
=5/8×4
=5/2
=2.5
