1
00:00:02,290 --> 00:00:05,700
欢迎收看基本加法的介绍

2
00:00:05,710 --> 00:00:09,890
我知道你在想什么! 你想: "加法不算太基本吧?"

3
00:00:09,900 --> 00:00:11,190
抱歉...

4
00:00:11,190 --> 00:00:16,090
希望在看完这介绍以后, 或许过一两周以后, 你会改观

5
00:00:16,100 --> 00:00:19,740
好, 我们先来看看一些...算是题目吧

6
00:00:19,740 --> 00:00:24,100
我们先从最熟悉的开始

7
00:00:24,100 --> 00:00:27,130
一加一

8
00:00:27,140 --> 00:00:29,690
你应该已经想到答案了吧?

9
00:00:29,690 --> 00:00:33,690
我还是想跟你讲一下这该怎么算, 说不定你没记住该怎么开始

10
00:00:33,700 --> 00:00:36,110
或许还没做到很灵活

11
00:00:36,110 --> 00:00:37,590
比方说...

12
00:00:37,600 --> 00:00:42,290
好, 比方说, 我有一个油梨 (又称牛油果) 吧

13
00:00:42,290 --> 00:00:47,850
如果我有一个油梨, 然后你在多给我另一个油梨

14
00:00:47,860 --> 00:00:50,130
那我现在有几个油梨呢?

15
00:00:50,140 --> 00:00:52,000
那是一, 二. 两个油梨

16
00:00:52,050 --> 00:00:55,540
所以一加一就是等于二

17
00:00:55,620 --> 00:00:56,680
好, 我知道你在想什么:

18
00:00:56,700 --> 00:00:58,290
"这也太简单了吧!"

19
00:00:58,290 --> 00:01:01,120
那我就给你一题比较难的

20
00:01:01,130 --> 00:01:02,590
我是喜欢油梨啦

21
00:01:02,670 --> 00:01:05,290
那就继续用它举例吧

22
00:01:05,290 --> 00:01:10,690
三加四是什么呢?

23
00:01:10,700 --> 00:01:13,290
这个嘛, 可能比较难一点点

24
00:01:13,290 --> 00:01:15,390
还是回到油梨

25
00:01:15,400 --> 00:01:17,290
啊, 如果你不知道油梨是什么

26
00:01:17,290 --> 00:01:19,990
那是一个非常好吃的水果

27
00:01:20,000 --> 00:01:21,970
它是水果中最高油份的

28
00:01:21,970 --> 00:01:24,990
你吃的时候可能根本不会觉得它是一个水果吧?

29
00:01:25,000 --> 00:01:28,630
好, 回到三个油梨

30
00:01:28,630 --> 00:01:29,990
一

31
00:01:30,000 --> 00:01:31,090
二

32
00:01:31,090 --> 00:01:32,790
三

33
00:01:32,790 --> 00:01:36,660
现到你说你再多给我四个油梨

34
00:01:36,670 --> 00:01:41,490
我把这四个涂上黄色, 那你认得这是你刚给我的

35
00:01:41,500 --> 00:01:42,590
一

36
00:01:42,590 --> 00:01:43,390
二

37
00:01:43,400 --> 00:01:44,990
三

38
00:01:45,000 --> 00:01:47,000
四

39
00:01:47,000 --> 00:01:48,960
那我现在有几个油梨呢?

40
00:01:49,080 --> 00:01:50,160
这是

41
00:01:50,160 --> 00:01:51,140
一

42
00:01:51,160 --> 00:01:51,980
二

43
00:01:52,000 --> 00:01:52,790
三

44
00:01:52,790 --> 00:01:53,490
四

45
00:01:53,500 --> 00:01:54,090
五

46
00:01:54,090 --> 00:01:54,890
六

47
00:01:54,900 --> 00:01:56,430
七个油梨

48
00:01:56,430 --> 00:01:59,760
所以呢, 三加四是等于七

49
00:01:59,760 --> 00:02:01,260
好我们现在从另一个角度再想一想

50
00:02:01,300 --> 00:02:03,300
这个叫做: 数字线

51
00:02:03,300 --> 00:02:06,190
我自己是这么想的

52
00:02:06,200 --> 00:02:07,700
当我有时候忘记

53
00:02:07,700 --> 00:02:09,690
没有背好做法的时候

54
00:02:09,690 --> 00:02:11,820
我就会把数字都顺序写在数字在线

55
00:02:11,830 --> 00:02:16,890
我会一直写下一个数字, 确定之后要用到的都写到了

56
00:02:16,900 --> 00:02:18,960
当然, 你也知道的, 第一个数字就是零了

57
00:02:18,960 --> 00:02:21,190
好就算你本来不知道, 你现在也晓得了吧?

58
00:02:21,190 --> 00:02:36,960
然后我们一个一个的往上数, 一, 二, 三, 四, 五, 六, 七, 八, 九, 十

59
00:02:37,060 --> 00:02:39,460
然后再继嬻, 十一...

60
00:02:39,470 --> 00:02:40,880
我们刚刚说的是三加四嘛

61
00:02:40,980 --> 00:02:43,040
所以就得从三开始

62
00:02:43,040 --> 00:02:45,130
这里是三

63
00:02:45,140 --> 00:02:46,890
我们要在三上加上四

64
00:02:46,900 --> 00:02:49,400
那就是要在数字在线往上走

65
00:02:49,400 --> 00:02:50,280
从本来的数字往右边去

66
00:02:50,280 --> 00:02:52,000
走四格

67
00:02:52,000 --> 00:02:53,090
好, 来啰?

68
00:02:53,090 --> 00:02:54,490
一

69
00:02:54,500 --> 00:02:55,690
二

70
00:02:55,690 --> 00:02:57,190
三

71
00:02:57,190 --> 00:03:00,090
四

72
00:03:00,090 --> 00:03:01,660
这样做就是从本来的加上: 一

73
00:03:01,670 --> 00:03:02,400
二

74
00:03:02,430 --> 00:03:02,930
三

75
00:03:02,930 --> 00:03:03,500
四

76
00:03:03,500 --> 00:03:04,960
最后到达了七这边

77
00:03:04,960 --> 00:03:07,190
那就是我们的答案了

78
00:03:07,190 --> 00:03:08,180
我们可以再试一下别的

79
00:03:08,190 --> 00:03:09,290
例如说

80
00:03:09,300 --> 00:03:10,800
这个是什么?

81
00:03:10,800 --> 00:03:13,310
如果我问你说八加一是什么?

82
00:03:13,310 --> 00:03:14,910
唔...八加一

83
00:03:14,920 --> 00:03:16,090
你可能已经想到了

84
00:03:16,090 --> 00:03:17,590
八加一就是八的下一个数字啊

85
00:03:17,590 --> 00:03:19,090
如果来我们走一下数字线

86
00:03:19,090 --> 00:03:21,090
你先从八开始

87
00:03:21,090 --> 00:03:23,490
加上一

88
00:03:23,500 --> 00:03:25,690
八加一就是等于九了

89
00:03:28,760 --> 00:03:31,200
我们再来做一些难一点的题目吧

90
00:03:31,200 --> 00:03:33,090
我先跟你说

91
00:03:33,090 --> 00:03:33,790
如果你一开始觉得有点困难

92
00:03:33,800 --> 00:03:35,490
你可以先画一画圈圈

93
00:03:35,500 --> 00:03:37,400
可以先画一画数字线

94
00:03:37,400 --> 00:03:38,800
然后慢慢地

95
00:03:38,800 --> 00:03:40,190
你越多加练习

96
00:03:40,190 --> 00:03:41,340
就越容易把这些都背起来了

97
00:03:41,350 --> 00:03:43,230
以后的话, 不用半秒你就可以想到了

98
00:03:43,230 --> 00:03:44,180
这我答应你

99
00:03:44,190 --> 00:03:46,110
只要努力练习就能做到

100
00:03:46,110 --> 00:03:47,590
好, 我们回去说

101
00:03:47,590 --> 00:03:48,620
先把数字线在画一画好了

102
00:03:48,670 --> 00:03:50,390
对了, 我可以用计算机工具画线

103
00:03:50,400 --> 00:03:51,690
不用让你看到这么丑的线

104
00:03:51,690 --> 00:03:53,960
好你看一下哦

105
00:03:53,970 --> 00:03:56,990
厉害吧?

106
00:03:59,810 --> 00:04:02,510
这直线好看多了

107
00:04:02,520 --> 00:04:05,440
待会我可能还不舍得删掉

108
00:04:05,530 --> 00:04:07,860
好先把数字写上去

109
00:04:07,900 --> 00:04:08,530
零

110
00:04:08,560 --> 00:04:09,190
一

111
00:04:09,200 --> 00:04:10,510
二

112
00:04:10,520 --> 00:04:12,190
三

113
00:04:12,190 --> 00:04:13,290
四

114
00:04:13,300 --> 00:04:14,890
五

115
00:04:14,900 --> 00:04:16,100
六

116
00:04:16,100 --> 00:04:17,390
七

117
00:04:17,390 --> 00:04:18,490
八

118
00:04:18,500 --> 00:04:20,100
九

119
00:04:20,100 --> 00:04:21,490
十

120
00:04:21,500 --> 00:04:22,890
十一

121
00:04:22,890 --> 00:04:24,290
十二

122
00:04:24,300 --> 00:04:25,690
十三

123
00:04:25,690 --> 00:04:27,090
十四

124
00:04:27,100 --> 00:04:29,600
十五

125
00:04:29,600 --> 00:04:31,720
我们先试一道难题

126
00:04:31,720 --> 00:04:34,040
什么是...

127
00:04:34,040 --> 00:04:36,190
哦我先用一下别的颜色

128
00:04:36,190 --> 00:04:39,350
什么是五加六呢?

129
00:04:39,370 --> 00:04:41,290
如果你想的话, 可以先暂停一下这短片试试看

130
00:04:41,300 --> 00:04:43,300
你可以已经想到答案了吧

131
00:04:43,300 --> 00:04:45,700
我之所以说这是一道难题

132
00:04:45,700 --> 00:04:48,670
是因为答案比我们的手指头多

133
00:04:48,680 --> 00:04:51,690
所以用手指头算也算不完

134
00:04:51,690 --> 00:04:55,190
好, 我们来看看怎么做

135
00:04:55,190 --> 00:04:56,190
( 哦, 我电话响了... )

136
00:04:56,190 --> 00:04:58,990
( 没关系, 我先不理它，因为你比较重要! )

137
00:04:59,000 --> 00:05:03,000
好, 我们从五开始

138
00:05:05,190 --> 00:05:06,680
要加上六

139
00:05:06,690 --> 00:05:07,590
那

140
00:05:07,600 --> 00:05:08,490
一

141
00:05:08,500 --> 00:05:09,690
二

142
00:05:09,690 --> 00:05:10,790
三

143
00:05:10,800 --> 00:05:11,690
四

144
00:05:11,690 --> 00:05:13,190
五

145
00:05:13,190 --> 00:05:15,590
六

146
00:05:15,600 --> 00:05:17,690
就到了十一了

147
00:05:17,690 --> 00:05:20,330
所以, 五加六的答案是十一

148
00:05:20,340 --> 00:05:22,190
我现在问你一下

149
00:05:22,190 --> 00:05:23,760
那六加五是什么呢?

150
00:05:29,680 --> 00:05:31,330
两个数字反过来了还是会得到同样的答案吗?

151
00:05:31,330 --> 00:05:32,690
我们来试一试好了

152
00:05:32,700 --> 00:05:33,700
我这一次再换一个颜色

153
00:05:33,710 --> 00:05:35,350
不然我们会搞乱

154
00:05:35,360 --> 00:05:37,630
那现在先从六开始

155
00:05:37,630 --> 00:05:39,390
先不看黄色的

156
00:05:39,390 --> 00:05:40,990
加五上去

157
00:05:41,000 --> 00:05:42,000
一

158
00:05:42,000 --> 00:05:43,100
二

159
00:05:43,100 --> 00:05:44,290
三

160
00:05:44,300 --> 00:05:44,990
四

161
00:05:45,000 --> 00:05:45,500
五

162
00:05:45,500 --> 00:05:46,100
看!

163
00:05:46,100 --> 00:05:48,190
到了同一点上去了!

164
00:05:48,190 --> 00:05:49,380
你也可以试一试不一样的题目

165
00:05:49,390 --> 00:05:51,200
结果还是会一样的

166
00:05:51,200 --> 00:05:53,690
数目的次序其实不要紧

167
00:05:53,690 --> 00:05:56,050
五加六其实跟六加五一样

168
00:05:56,060 --> 00:05:57,270
这挺好理解的

169
00:05:57,280 --> 00:06:00,140
比方说我有五个油梨然后你给我六个, 我就有十一个

170
00:06:00,140 --> 00:06:03,190
或者我有六个油梨然后你给我五, 我还是会有十一个

171
00:06:05,460 --> 00:06:07,140
既后数字线这么好用

172
00:06:07,140 --> 00:06:08,730
我想在好好用它算一下别的题目

173
00:06:08,730 --> 00:06:10,850
虽然这样可能会把你也搞胡涂了

174
00:06:10,860 --> 00:06:12,310
你看我已经写了那么多在上面

175
00:06:13,680 --> 00:06:14,900
再看看吧

176
00:06:14,900 --> 00:06:15,830
我用一下白色

177
00:06:16,870 --> 00:06:22,910
八加七是什么?

178
00:06:22,920 --> 00:06:24,080
好

179
00:06:24,080 --> 00:06:25,020
如果你还读得到的话

180
00:06:25,030 --> 00:06:27,460
八就在这

181
00:06:27,460 --> 00:06:29,330
我们要加七上去

182
00:06:29,430 --> 00:06:30,210
一

183
00:06:30,220 --> 00:06:31,110
二

184
00:06:31,110 --> 00:06:32,540
三

185
00:06:32,540 --> 00:06:33,580
四

186
00:06:33,590 --> 00:06:34,790
五

187
00:06:34,800 --> 00:06:35,600
六

188
00:06:35,600 --> 00:06:37,300
七

189
00:06:37,300 --> 00:06:39,290
我们到十五了

190
00:06:39,300 --> 00:06:43,490
八加七是十五

191
00:06:43,500 --> 00:06:47,500
这下来, 希望你大既知道怎么做这种题目

192
00:06:47,500 --> 00:06:51,890
还有的是, 我猜你马上就要学到乘法了

193
00:06:51,890 --> 00:06:54,160
这种题目嘛

194
00:06:54,170 --> 00:06:55,940
在一开始学习数学的时候

195
00:06:55,950 --> 00:06:58,390
是需要很多的练习的

196
00:06:58,390 --> 00:07:00,020
可能还要熟悉到要背下来的样子

197
00:07:00,030 --> 00:07:03,390
可是时间久了, 你再回头看

198
00:07:03,390 --> 00:07:05,900
我想你记住现在看这个的感觉

199
00:07:05,910 --> 00:07:09,840
然后三年后再回来从看一次

200
00:07:09,840 --> 00:07:11,860
到时候你要记得现在在看的感觉

201
00:07:11,860 --> 00:07:14,780
因为你就会想: "天啊, 这还太简单了吧?"

202
00:07:14,790 --> 00:07:16,570
因为你其实会学习得很快的

203
00:07:16,710 --> 00:07:17,590
好吧

204
00:07:18,800 --> 00:07:20,590
我想你已经大既有个慨念了

205
00:07:20,590 --> 00:07:24,590
如果你在做练习题的时候找不出答案

206
00:07:24,590 --> 00:07:26,170
记得可以按一下 "提示"

207
00:07:26,170 --> 00:07:27,590
然后计算机会给你画一下圈圈

208
00:07:27,600 --> 00:07:28,970
你就可以数圈圈

209
00:07:28,970 --> 00:07:30,690
或者是如果你想自己来的话

210
00:07:30,690 --> 00:07:31,600
也可以自己来算算

211
00:07:31,610 --> 00:07:33,090
用画圈圈的方法

212
00:07:33,100 --> 00:07:34,990
或者上数字线的方法

213
00:07:35,000 --> 00:07:37,690
就像我们刚刚说的一样

214
00:07:37,690 --> 00:07:40,590
怎么样? 我看你已经准备好了

215
00:07:41,040 --> 99:59:59,999
好好试一下吧!
