一、直接写出得数。（每题1分，共32分）
2.8 + 0.2 =
201 + 89 =
96 ÷ 24 =
56 + 39 + 44 =
270 - 130 =
147 - 36 =
23 × 30 =
4.3 - 0.8 + 1.2 =
52 ÷ 2 =
120 ÷ 40 =
81 ÷ 27 =
11 + 99 × 11 =
386 ÷ 2 =
5.6 - 0.7 =
4.3 + 0.36 =
660 ÷ 22 ÷ 3 =
8 × 50 =
450 × 2 =
328 ÷ 4 =
8.9 + 0.3 - 9 =
65 × 4 =
400 ÷ 40 =
120 × 5 =
129 - (47 + 29) =
25 × 20 =
6.2 - 0.14 =
91 ÷ 7 =
330 × 4 ÷ 11 =
70 × 12 =
740 + 200 =
540 ÷ 5 =
65 × 120 - 65 × 20 =

3 290 4 139 140 111 690 4.7 26 3 3 1100 193 4.9 4.66 10 400 900 82 0.2 260 10 600 53 500 6.06 13 120 840 940 108 6500

二、用竖式计算，带☆的要验算。（每题3分，验算各1分，共20分）
8.53＋6.5＝
☆835÷42＝
127×63＝
624÷26＝
450×46＝
☆24.8－5.72＝

15.03
19……37
8001

20700
19.08
竖式及验算略

三、计算下面各题，能简算的要简算。(每题3分，共18分)
143 + 122 - 43 + 78
79 × (44 - 18) - 360
(50 + 41) × 20 ÷ 13
20.59 - 8.3 + 4.7
99 × 99 + 199
420 ÷ [(203 - 196) × 4]
