综合套题十
30 ÷ 10000 =	7.1 + 7.63 =	24 ×125 =
500 ÷ 25 =	49 +854 =	1.8 ÷ 100 =
60 - 9.86 =	8.1 - 3.8 =	160 - 90 =
2.96 × 1000 =	31.8 × 10 =	78.9 + 38.2 =
2、简便计算
125 × (8 × 79 )	( 125 + 40 ) × 8	6.82 + 6.26 + 3.21 + 1.74 + 5.79
999 × 414 + 414	9000 ÷ 8 ÷ 125	705 - (105 + 284 )
3、四则运算与灵活运用
5.61 - 1.36 + 0.39	805 × 98	( 230 + 435 ) ÷ 5
932×453-49×932-932×4	3.42 - 1.7 + 7.08	132 - 390 ÷ 13 ÷ 15
(213 ÷ 3 + 68) × 9	4×[(300-30)÷9+128]	592 ÷ 56 × 28
