综合套题十
510 - 70 =	18.7 + 13.9 =	60 ×56 =
4.9 ÷ 100 =	4.5 + 1.45 =	98 +833 =
5.29 × 1000 =	50 - 4.36 =	700 ÷ 25 =
60 ÷ 1000 =	77.9 × 10 =	9.1 - 8.7 =
2、简便计算
32 × 8 × 125	9.08 + 5.36 + 5.19 + 2.64 + 3.81	9000 ÷ 125 ÷ 8
8.24 - 1.02 - 1.98	( 25 + 300 ) × 4	734 × 523 + 734 × 477
3、四则运算与灵活运用
9.19 - 7.6 + 7.18	392 - 3420 ÷ (18 × 10)	9193 - (436 + 393 )
986 × 999	[(251+43)÷6+175]×5	413×893-39×413-413×54
452 ÷ 92 × 23	694 - ( 194 - 685 )	893 + 108 ÷ 4 × 5
