2026年暑假乐园海南出版社一年级数学人教版第39页答案
一、快来算一算。
84 - 40 =
59 - 7 =
73 - 70 =
56 - 3 =
36 - 20 =
89 - 70 =
75 - 60 =
83 - 80 =
59 - 3 =
89 - 8 =
74 - 4 =
69 - 20 =

答案

84 - 40 = 44
59 - 7 = 52
73 - 70 = 3
56 - 3 = 53
36 - 20 = 16
89 - 70 = 19
75 - 60 = 15
83 - 80 = 3
59 - 3 = 56
89 - 8 = 81
74 - 4 = 70
69 - 20 = 49
二、在正确的得数上画“√”。
38 - 30 + 9 = (37, 9, 17)
30 + 48 - 30 = (30, 48, 8)
6 + 30 + 50 = (86, 76, 66)
92 - 2 - 90 = (90, 0, 1)

答案

38 - 30 + 9 = (37, 9, 17√)
30 + 48 - 30 = (30, 48√, 8)
6 + 30 + 50 = (86√, 76, 66)
92 - 2 - 90 = (90, 0√, 1)
三、在○里填上“＞”“＜”或“=”。
8 + 74 ○ 80
58 ○ 16 + 40
49 + 6 ○ 60
32 + 8 ○ 56 - 10
80 - 80 ○ 6 - 6
47 + 30 ○ 47 + 3

答案

8+74=82
82＞80
8 + 74 ＞ 80
16+40=56
58＞56
58 ＞ 16 + 40
49+6=55
55＜60
49 + 6 ＜ 60
32+8=40
56-10=46
40＜46
32 + 8 ＜ 56 - 10
80-80=0
6-6=0
0=0
80 - 80 = 6 - 6
47+30=77
47+3=50
77＞50
47 + 30 ＞ 47 + 3
