解析

65 + 36 = 101
52 ÷ 26 = 2
5 × 92 = 460
147 - 98 = 49
25 × 80 = 2000
780 ÷ 13 = 60
570 ÷ 3 = 190
46 + 16 = 62
60 × 90 = 5400
26 × 30 = 780
108 ÷ 3 = 36
100 - 48 = 52
265 ÷ 5 = 53
18 × 50 = 900
600 ÷ 60 = 10
42 ÷ 14 = 3
300 - 60 = 240
11 × 60 = 660
100 ÷ 25 = 4
120 × 8 = 960
350 ÷ 2 = 175
6400 ÷ 400 = 16
750 ÷ 25 = 30
200 - 50 = 150
二、计算下面各题。
713 - 146 ÷ 73 × 98
812 - (278 + 322) ÷ 15
[206 - (63 + 72)] × 58
29 × 23 - 308 + 68
(79 - 26) × (71 + 26)
700 ÷ [(205 - 198) × 4]

答案

二、517 772 4118 427 5141 25

解析

713 - 146 ÷ 73 × 98
= 713 - 2 × 98
= 713 - 196
= 517
812 - (278 + 322) ÷ 15
= 812 - 600 ÷ 15
= 812 - 40
= 772
[206 - (63 + 72)] × 58
= [206 - 135] × 58
= 71 × 58
= 4118
29 × 23 - 308 + 68
= 667 - 308 + 68
= 359 + 68
= 427
(79 - 26) × (71 + 26)
= 53 × 97
= 5141
700 ÷ [(205 - 198) × 4]
= 700 ÷ [7 × 4]
= 700 ÷ 28
= 25
