1. 直接写出得数。
46 + 44 = 90
48 + 52 = 100
51 ÷ 3 = 17
17 + 23 + 40 = 80
200 × 6 = 1200
76 - 24 = 52
404 × 3 = 1212
148 - 48 + 30 = 130
2 × 25 = 50
300 × 6 = 1800
68 ÷ 4 = 17
400 ÷ 8 × 5 = 250
230 + 140 = 370
40 × 7 = 280
81 ÷ 3 = 27
720 ÷ 8 - 30 = 60
400 × 5 = 2000
93 ÷ 3 = 31
15 + 396 = 411
180 - 40 × 3 = 60
300 ÷ 5 = 60
21 × 4 = 84
255 ÷ 5 = 51
60 + 40 × 2 = 140
20 × 9 = 180
164 ÷ 4 = 41
130 ÷ 5 = 26
15 × 0 + 80 = 80
270 ÷ 3 = 90
560 ÷ 7 = 80
24 × 6 = 144
25 × 4 × 7 = 700

答案： 90 100 17 80 1200 52 1212 130 50 1800 17 250 370 280 27 60 2000 31 411 60 60 84 51 140 180 41 26 80 90 80 144 700

2. 用竖式计算。
143 × 6 = 858
40 × 39 = 1560
820 ÷ 7 = 117……1
301 ÷ 8 = 37……5
846 ÷ 3 = 282
49 × 38 = 1862（竖式略）

答案： 858 1560 117……1 37……5 282 1862（竖式略）

= (400)毫升
= (100)毫升

答案： 400 100
