故答案为:
,191,1,18,
,
.
分析:(1)从左往右按顺序计算即可;
(2)同时脱式,先求出35×6和513÷27的结果,再计算减法;
(3)把(9
+1
-5
)÷(9
-6
+2
)改写成(9
+1
-5
)÷(9
-6+1
+2-1
),进而(9
+1
-5
)÷(9
-5
+1
),分子分母变成一样,所以最后结果是1;
(4)把18%改写成1.8×0.1,再逆用乘法分配律简算;
(5)把
×[
-(
-
)]改写成
×[
+
-
],进而简算;
(6)把(1-
)(1-
)(1-
)…(1-
)改写成(1-
)(1+
)(1-
)(1+
)…(1-
)(1+
),进而等于
×
