综合套题十
65 ×20 =	36.4 × 100 =	9.55 × 1000 =
41.8 + 41.4 =	60 ÷ 10000 =	800 ÷ 25 =
7.3 + 1.46 =	350 - 90 =	5.8 ÷ 1000 =
3.8 - 1.9 =	63 +189 =	40.54 - 7.6 =
2、简便计算
13 × 109	148 + 621 + 552 + 130 + 279	101 × 834 - 834
90000 ÷ (125 × 90 )	55 × 8 × 125	7.74 - (4.74 + 2.84 )
3、四则运算与灵活运用
25 × 32 × 125	375 ÷ 25	834 - 141 - 434
351 ÷ 13 ÷ 3 + 283	[(323+27)÷7+205]×6	8.9 - 5.8 + 1.2
162 ÷ 18	1 - 2.09 + 8	710 - 624 ÷ 8 + 123
