直接写出下面各题的得数． 16×101=	0.9×99+0.9=	3.14×6=	4 5 - 1 2 =
9 20 - 2 5 + 11 20 =	3 7 × 5 4 × 7 9 =	4 7 ÷4=	6×（ 5 12 + 1 6 ）=
2- 4 9 - 5 9 =	8 25 ÷ 4 5 =	6- 3 10 =	5 12 + 1 4 - 5 12 + 1 4 =

Answer 1

分析：根据四则运算顺序计算，能巧算的可以巧算．

解答：

解：16×101=1616	0.9×99+0.9=90	3.14×6=18.84	4 5 - 1 2 = 3 10
9 20 - 2 5 + 11 20 = 3 5	3 7 × 5 4 × 7 9 = 5 12	4 7 ÷4= 1 7	6×（ 5 12 + 1 6 ）= 7 2
2- 4 9 - 5 9 =1	8 25 ÷ 4 5 = 2 5	6- 3 10 =5 7 10	5 12 + 1 4 - 5 12 + 1 4 = 1 2

点评：根据计算方法计算，能巧算的要巧算．
