综合套题十
40 ÷ 10000 =	60.81 - 5.9 =	65.3 + 31.8 =
8.9 + 1.61 =	700 ÷ 25 =	310 - 90 =
40 ×125 =	16.7 × 100 =	1.8 ÷ 1000 =
157 +65 =	7.6 - 6.8 =	2.99 × 1000 =
2、简便计算
99 × 397 + 397	11 × 125 × 8	9000 ÷ 25 ÷ 4
514 - (114 + 327 )	397 + 291 + 512 + 403 + 288	15 × 1001
3、四则运算与灵活运用
200 ÷ 25	2×[170÷(39-34)+334]	249 - 210 ÷ 2 ÷ 15
125 × 44 × 25	5108 - 986 - 914 - 708	266 + 70 × 7 - 299
252 ÷ 36	675 - ( 475 - 343 )	6.6 - 1.6 + 4.31
