综合套题十
600 ÷ 25 =	640 - 70 =	71.6 + 59 =
25 ×32 =	8.4 ÷ 1000 =	4.1 - 3.85 =
19 +599 =	30 ÷ 10000 =	45.1 × 100 =
7.56 × 1000 =	9.4 - 4.7 =	15.4 + 78.8 =
2、简便计算
5.24 + 1.33 + 3.42 + 2.67 + 2.58	838 - (288 + 438 )	86000 ÷ (86 × 25 )
1003 × 13	38 × 8 × 125	944 × 307 + 944 × 693
3、四则运算与灵活运用
(588 ÷ 7 + 805) × 8	966 - 121 + 129	9.7 - 8 + 3
( 335 + 285 ) ÷ 5	621 - 152 - 421	4×[(71-50)×6+423]
179 - 1008 ÷ 16 ÷ 9	486 ÷ 27	125 × 32 × 25
