1
00:00:00,000 --> 00:00:36,399
Temos 2, 3, 0, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4

2
00:00:36,399 --> 00:01:12,489
É só o que eu te digo.

3
00:01:12,510 --> 00:01:14,510
Aplausos

4
00:01:42,510 --> 00:01:43,510
O portavoz.

5
00:01:45,689 --> 00:01:46,310
O portavoz?

6
00:01:46,549 --> 00:01:46,989
Non, eu.

7
00:01:48,090 --> 00:01:48,650
Tu?

8
00:01:49,010 --> 00:01:49,370
Eu.

9
00:01:51,790 --> 00:01:52,569
E tu?

10
00:01:53,569 --> 00:01:54,170
Eu.

11
00:01:54,170 --> 00:01:54,849
Ah, ben.

12
00:01:56,390 --> 00:01:57,829
Claro, claro, eh?

13
00:01:58,390 --> 00:01:58,750
Si.

14
00:01:59,629 --> 00:02:02,150
Só que é que eleixen tres cosas e son tres.

15
00:02:04,290 --> 00:02:06,170
Non parece fácil, pero...

16
00:02:07,170 --> 00:02:07,909
Añade un pouco.

17
00:02:07,950 --> 00:02:09,169
Tres puestos, tres persoas...

18
00:02:09,169 --> 00:02:23,270
Si tengo un palomar

19
00:02:23,270 --> 00:02:24,310
Vamos a suponer

20
00:02:24,310 --> 00:02:26,009
Con 20 casas

21
00:02:26,009 --> 00:02:29,370
Y tengo 21 palomas

22
00:02:29,370 --> 00:02:32,210
Y todas las palomas

23
00:02:32,210 --> 00:02:33,550
Van a su casa

24
00:02:33,550 --> 00:02:36,270
Está claro que en alguna casa

25
00:02:36,270 --> 00:02:37,849
Hay dos palomas

26
00:02:37,849 --> 00:02:40,189
Como mini

27
00:02:40,189 --> 00:02:41,810
Como mini, claro

28
00:02:41,810 --> 00:02:43,289
Que parece?

29
00:02:44,770 --> 00:02:45,909
Debería de salvar

30
00:02:45,909 --> 00:02:47,949
Pois sirve para resolver un montón de problemas

31
00:02:47,949 --> 00:02:58,530
Claro, pero se te sobran cinco

32
00:02:58,530 --> 00:02:59,909
Se te sobran cinco

33
00:02:59,909 --> 00:03:01,430
Casas

34
00:03:01,430 --> 00:03:04,430
Como que se me sobran cinco?

35
00:03:04,669 --> 00:03:05,389
Se te sobran cinco

36
00:03:05,389 --> 00:03:09,610
Bueno, en realidad é unha paloma

37
00:03:09,610 --> 00:03:11,210
que se queres N

38
00:03:11,210 --> 00:03:13,349
N casas

39
00:03:13,349 --> 00:03:15,250
e en unha paloma

40
00:03:15,250 --> 00:03:17,150
ou en unhas K palomas

41
00:03:17,150 --> 00:03:19,169
é claro que non é unha casa

42
00:03:19,169 --> 00:03:20,789
é unha paloma

43
00:03:20,789 --> 00:03:27,030
Bueno, venga

44
00:03:27,030 --> 00:03:28,069
Que salón é este?

45
00:03:30,500 --> 00:03:31,900
Corra 2

46
00:03:31,900 --> 00:03:34,139
Corra 2

47
00:03:34,139 --> 00:03:35,620
Luis, por que?

48
00:03:35,620 --> 00:03:36,979
rola

49
00:03:36,979 --> 00:03:38,259
por el final

50
00:03:38,259 --> 00:03:39,400
vale

51
00:03:39,400 --> 00:04:00,699
venga, vamos a ver

52
00:04:00,699 --> 00:04:01,620
vamos a hacer

53
00:04:01,620 --> 00:04:02,699
eh

54
00:04:02,699 --> 00:04:05,340
venga

55
00:04:05,340 --> 00:04:08,219
si, venga

56
00:04:11,639 --> 00:04:13,280
é como unha guía

57
00:04:13,280 --> 00:04:14,080
óptica

58
00:04:14,080 --> 00:04:22,000
é como sacar

59
00:04:22,000 --> 00:04:24,079
a actividade

60
00:04:24,079 --> 00:04:31,110
a actividade

61
00:04:31,110 --> 00:04:32,649
dice que hay que hacer

62
00:04:32,649 --> 00:04:34,509
como unha especie de corte

63
00:04:34,509 --> 00:04:36,110
e resumen, pero vamos a hacer así

64
00:04:36,110 --> 00:04:37,430
a hablar, verdad?

65
00:04:38,290 --> 00:04:39,149
que dice

66
00:04:39,149 --> 00:04:42,610
que podemos hacer como resumen

67
00:04:42,610 --> 00:04:45,009
el ahora en corte

68
00:04:45,009 --> 00:04:49,769
Vamos a definir para que

69
00:04:49,769 --> 00:04:51,569
A regla dos signos

70
00:04:51,569 --> 00:04:52,550
Para que descubrirlo

71
00:04:52,550 --> 00:04:54,129
A ver, portavoz

72
00:04:54,129 --> 00:04:57,410
Qual é a regla dos signos

73
00:04:57,410 --> 00:04:58,790
Para que descubrirlo

74
00:04:58,790 --> 00:05:00,990
A ver

75
00:05:00,990 --> 00:05:02,290
Decide

76
00:05:02,290 --> 00:05:04,209
O resto, acento

77
00:05:04,209 --> 00:05:06,050
Esta predicción é correcta

78
00:05:06,050 --> 00:05:07,209
Porque a regla dos signos

79
00:05:07,209 --> 00:05:09,449
A hora de dividir

80
00:05:09,449 --> 00:05:10,329
O infinitado

81
00:05:10,329 --> 00:05:13,750
É que se hai dos más positivos

82
00:05:13,750 --> 00:05:14,829
por positivo

83
00:05:14,829 --> 00:05:16,810
é resultado positivo

84
00:05:16,810 --> 00:05:18,449
pero se é ACB

85
00:05:18,449 --> 00:05:21,250
positivo por menos

86
00:05:21,250 --> 00:05:23,350
é negativo

87
00:05:23,350 --> 00:05:25,149
resultado negativo

88
00:05:25,149 --> 00:05:27,490
porque se os signos son iguales é positivo

89
00:05:27,490 --> 00:05:29,029
pero se non son iguales

90
00:05:29,029 --> 00:05:30,329
é negativo

91
00:05:30,329 --> 00:05:31,449
¿Queréis saber algo?

92
00:05:31,649 --> 00:05:31,990
No

93
00:05:31,990 --> 00:05:35,610
Equipo 2

94
00:05:35,610 --> 00:05:41,290
¿Qué diríais

95
00:05:41,290 --> 00:05:43,250
de como se multiplica o número de signos?

96
00:05:43,750 --> 00:05:45,529
E como se multiplica?

97
00:05:45,709 --> 00:05:48,089
Si, como diríais unha regla para multiplicar o resultado?

98
00:05:48,949 --> 00:05:49,610
Ah, pois

99
00:05:49,610 --> 00:05:52,189
Cando unha de las dos números

100
00:05:52,189 --> 00:05:53,370
Pase a multiplicar

101
00:05:53,370 --> 00:05:56,470
Se unha deles é negativa

102
00:05:56,470 --> 00:05:58,490
E o outro positivo

103
00:05:58,490 --> 00:06:00,290
Sempre é o resultado negativo

104
00:06:00,290 --> 00:06:01,910
Pero se unha

105
00:06:01,910 --> 00:06:03,850
Se os dois son positivos

106
00:06:03,850 --> 00:06:04,870
Ou negativos

107
00:06:04,870 --> 00:06:06,029
Se faz positivo

108
00:06:06,029 --> 00:06:09,509
Vale, equipo 3

109
00:06:09,509 --> 00:06:10,730
A mano está mojada

110
00:06:10,730 --> 00:06:11,589
Vale, perdón

111
00:06:11,589 --> 00:06:14,829
Como habéis deducido

112
00:06:14,829 --> 00:06:16,829
Como habéis deducido que

113
00:06:16,829 --> 00:06:18,290
Si cojo un número positivo

114
00:06:18,290 --> 00:06:20,829
E nos multiplico por un número negativo

115
00:06:20,829 --> 00:06:22,029
Sale negativo

116
00:06:22,029 --> 00:06:24,110
Pois porque hai diferencias

117
00:06:24,110 --> 00:06:26,569
Porque hai diferencias

118
00:06:26,569 --> 00:06:28,490
É como la tabla original

119
00:06:28,490 --> 00:06:30,110
Pero como está en negativo

120
00:06:30,110 --> 00:06:31,509
Pois bajas para baixo

121
00:06:31,509 --> 00:06:33,509
Entón, pois

122
00:06:33,509 --> 00:06:35,889
Menos 3 por 2

123
00:06:35,889 --> 00:06:37,009
Sería menos 3

124
00:06:37,009 --> 00:06:39,569
Porque menos 3 é o oposto de 3

125
00:06:39,569 --> 00:06:43,730
Sempre que hai un menos, todo o menos, vai ser negativo o resultado.

126
00:06:43,949 --> 00:06:45,029
Si, pero eu quero saber por que.

127
00:06:46,050 --> 00:06:48,269
Eu quero saber como o habéis sacado.

128
00:06:48,889 --> 00:06:49,389
Dime, Laura.

129
00:06:49,410 --> 00:06:50,129
Menos e máis.

130
00:06:50,970 --> 00:06:51,889
Menos e máis?

131
00:06:52,149 --> 00:06:53,829
Non entendo que é menos e máis.

132
00:06:53,930 --> 00:06:56,889
Qualquer número negativo e número positivo, ganáis o número negativo.

133
00:06:57,470 --> 00:06:59,009
Así, eu os cojo e digo, é.

134
00:06:59,170 --> 00:06:59,810
Non, pero...

135
00:06:59,810 --> 00:07:00,490
É negativo?

136
00:07:00,930 --> 00:07:01,589
Non, non, non.

137
00:07:02,589 --> 00:07:03,069
Si, caí.

138
00:07:04,509 --> 00:07:06,009
Mirad o que habéis feito.

139
00:07:06,629 --> 00:07:07,509
Oito por sete.

140
00:07:08,170 --> 00:07:08,670
Cuanto dá?

141
00:07:08,670 --> 00:07:11,009
56

142
00:07:11,009 --> 00:07:12,129
8 por 6

143
00:07:12,129 --> 00:07:18,550
A ver os observadores

144
00:07:18,550 --> 00:07:21,709
Tirad

145
00:07:21,709 --> 00:07:23,329
Espera, os observadores

146
00:07:23,329 --> 00:07:29,480
56

147
00:07:29,480 --> 00:07:31,319
8 por 7

148
00:07:31,319 --> 00:07:32,240
8 por 6

149
00:07:32,240 --> 00:07:35,540
48

150
00:07:35,540 --> 00:07:37,399
8 por 5

151
00:07:37,399 --> 00:07:41,589
8 por

152
00:07:41,589 --> 00:07:44,769
32

153
00:07:44,769 --> 00:07:47,310
8 por 3

154
00:07:47,310 --> 00:07:50,050
8 por 2

155
00:07:50,050 --> 00:07:51,790
8 por 1

156
00:07:51,790 --> 00:07:53,509
8 por 0

157
00:07:53,509 --> 00:07:55,149
E aquí

158
00:07:55,149 --> 00:07:57,529
Acabaría a serie

159
00:07:57,529 --> 00:07:59,470
Se estivéssemos en números

160
00:07:59,470 --> 00:08:01,990
Naturales

161
00:08:01,990 --> 00:08:02,730
Isto é

162
00:08:02,730 --> 00:08:04,269
8 por 7

163
00:08:04,269 --> 00:08:09,009
8 por 6

164
00:08:09,009 --> 00:08:10,310
E aquí 8 por 0

165
00:08:10,310 --> 00:08:15,269
Pero si tengo números enteros

166
00:08:15,269 --> 00:08:17,250
Puedo seguir la serie

167
00:08:17,250 --> 00:08:18,829
¿Ahora que iría?

168
00:08:19,410 --> 00:08:21,189
Menos 8 por menos 1

169
00:08:21,189 --> 00:08:22,370
8 por menos 1

170
00:08:22,370 --> 00:08:27,250
¿Y eso cuánto va a dar?

171
00:08:27,490 --> 00:08:28,529
Siguiendo la serie

172
00:08:28,529 --> 00:08:31,410
Luisito

173
00:08:31,410 --> 00:08:35,070
¿Qué característica tiene esta serie?

174
00:08:35,509 --> 00:08:36,970
A ver, reír en el observador

175
00:08:36,970 --> 00:08:38,990
¿Qué característica tiene esta serie?

176
00:08:38,990 --> 00:08:43,350
Pois é, claro, é o mesmo

177
00:08:43,350 --> 00:08:48,129
Que teña de especial esta serie?

178
00:08:49,009 --> 00:08:49,710
De cara a que

179
00:08:49,710 --> 00:08:52,129
Con unha de las que vos

180
00:08:52,129 --> 00:08:53,470
Sabes a serie

181
00:08:53,470 --> 00:08:55,250
Eu non te entendo

182
00:08:55,250 --> 00:08:57,669
Repite, repite

183
00:08:57,669 --> 00:08:59,809
Que significa é ao revés?

184
00:09:01,070 --> 00:09:02,350
Eu non estou perguntando

185
00:09:02,350 --> 00:09:03,730
Estou perguntando

186
00:09:03,730 --> 00:09:04,809
Esas seis de números

187
00:09:04,809 --> 00:09:07,210
Que características ten?

188
00:09:08,990 --> 00:09:18,970
Pois de cara ao 4, hai unha serie de 0, 8, 6, 4

189
00:09:18,970 --> 00:09:23,690
É esa

190
00:09:23,690 --> 00:09:28,029
É a mesma tabla que a original

191
00:09:28,029 --> 00:09:30,330
É unha tabla que está con unha...

192
00:09:30,330 --> 00:09:33,210
Si, ha dicho ben, porque o tempo ha deixado de contexto

193
00:09:33,210 --> 00:09:37,570
Dime a razón, porque as unidades de...

194
00:09:37,570 --> 00:09:39,529
É o que dixo eu

195
00:09:39,529 --> 00:09:44,009
As unidades siguen unha serie que é 0, 8, 6, 4, 2 de abaixo

196
00:09:44,009 --> 00:09:47,049
Curioso, curioso, mira

197
00:09:47,049 --> 00:09:52,090
6, 8, 0, 2, 4, 6, 8, 0

198
00:09:52,090 --> 00:09:55,070
¿Ahora que tocaría?

199
00:09:56,690 --> 00:09:58,230
6, 0, devolverlo porque

200
00:09:58,230 --> 00:10:01,009
Después, las decenas

201
00:10:01,009 --> 00:10:04,230
Son una serie de números consecutivos

202
00:10:04,230 --> 00:10:07,690
En la cual siempre se repiten los números de 4

203
00:10:07,690 --> 00:10:12,090
Por lo tanto, 0, 4, 8, 12

204
00:10:12,090 --> 00:10:13,970
O sea, 12 de 120

205
00:10:13,970 --> 00:10:17,509
El 2 de 120 se va a repetir

206
00:10:17,509 --> 00:10:19,350
O sea, va a ser 120, 128

207
00:10:19,350 --> 00:10:22,269
Vale, eso si subo

208
00:10:22,269 --> 00:10:23,350
Pero es que yo estoy bajando

209
00:10:23,350 --> 00:10:26,370
De 56 a 48

210
00:10:26,370 --> 00:10:29,289
De 48

211
00:10:29,289 --> 00:10:31,629
A 40

212
00:10:31,629 --> 00:10:33,370
De 40

213
00:10:33,370 --> 00:10:35,629
A 32

214
00:10:35,629 --> 00:10:36,909
De 32

215
00:10:36,909 --> 00:10:38,330
A 24

216
00:10:38,330 --> 00:10:40,230
¿Cuánto estoy bajando?

217
00:10:40,350 --> 00:10:40,769
8

218
00:10:40,769 --> 00:10:42,129
Oito

219
00:10:42,129 --> 00:10:43,750
Oito

220
00:10:43,750 --> 00:10:46,470
56 menos 8

221
00:10:46,470 --> 00:10:46,970
Vale

222
00:10:46,970 --> 00:10:52,470
Vale, e o zero?

223
00:10:53,730 --> 00:10:55,330
E o número natural

224
00:10:55,330 --> 00:10:58,289
O número natural

225
00:10:58,289 --> 00:10:59,049
Que queda en 0

226
00:10:59,049 --> 00:11:00,730
Pero o número entero

227
00:11:00,730 --> 00:11:03,350
Bajo al menos 8

228
00:11:03,350 --> 00:11:04,429
E se

229
00:11:04,429 --> 00:11:06,389
Poden seguir bajando?

230
00:11:06,870 --> 00:11:07,509
Si

231
00:11:07,509 --> 00:11:09,029
Poden seguir bajando?

232
00:11:09,129 --> 00:11:09,370
Si

233
00:11:09,370 --> 00:11:10,750
¿Puedo seguir bajando?

234
00:11:11,250 --> 00:11:11,509
Sí

235
00:11:11,509 --> 00:11:15,230
¿Pero con que signo?

236
00:11:15,529 --> 00:11:16,789
Con menos

237
00:11:16,789 --> 00:11:18,809
¿Entendéis lo que estoy diciendo?

238
00:11:19,250 --> 00:11:21,389
O sea que podríamos decir que un número positivo

239
00:11:21,389 --> 00:11:22,370
Con un número negativo

240
00:11:22,370 --> 00:11:24,710
Da negativo

241
00:11:24,710 --> 00:11:26,730
Porque si continuo a la serie

242
00:11:26,730 --> 00:11:29,149
Cuando llegue al cero

243
00:11:29,149 --> 00:11:31,389
A partir del cero como la salida del número

244
00:11:31,389 --> 00:11:36,320
¿Entendéis lo que estoy diciendo?

245
00:11:37,679 --> 00:11:38,879
Y la otra serie

246
00:11:38,879 --> 00:11:40,940
Y esta por ejemplo

247
00:11:40,940 --> 00:11:46,200
Esta, que diferencia tenéis con a outra?

248
00:11:50,210 --> 00:11:51,769
Pois que todo este final

249
00:11:51,769 --> 00:11:52,909
O de 0 o de 5

250
00:11:52,909 --> 00:11:55,210
Vale, pero alguna diferencia con a outra?

251
00:11:55,769 --> 00:11:55,950
Non

252
00:11:55,950 --> 00:11:56,710
Si

253
00:11:56,710 --> 00:11:57,250
Qual?

254
00:11:57,250 --> 00:11:58,049
Eu digo que unha

255
00:11:58,049 --> 00:11:59,110
Qual?

256
00:11:59,230 --> 00:12:00,809
Antes iba de 8 a 8

257
00:12:00,809 --> 00:12:02,809
Como ha dicho el autado

258
00:12:02,809 --> 00:12:04,110
Os números finales

259
00:12:04,110 --> 00:12:05,289
Os múltiplos de 4

260
00:12:05,289 --> 00:12:08,250
E agora son só o 5 o 0

261
00:12:08,250 --> 00:12:09,570
E non veis outra diferencia?

262
00:12:10,190 --> 00:12:11,470
Mirar, como a de arriba?

263
00:12:12,470 --> 00:12:13,029
Mirar

264
00:12:13,029 --> 00:12:15,009
¿Qué pone ahí?

265
00:12:16,110 --> 00:12:16,429
8

266
00:12:16,429 --> 00:12:17,850
A lo mejor se lo leéis en constante

267
00:12:17,850 --> 00:12:18,629
Os dejo ahí

268
00:12:18,629 --> 00:12:19,929
8 por 2

269
00:12:19,929 --> 00:12:21,090
Ruth, lee

270
00:12:21,090 --> 00:12:22,769
8 por 3

271
00:12:22,769 --> 00:12:24,389
8 por 2

272
00:12:24,389 --> 00:12:25,169
8 por 2

273
00:12:25,169 --> 00:12:26,190
8 por 1

274
00:12:26,190 --> 00:12:27,029
8 por 1

275
00:12:27,029 --> 00:12:28,269
8 por 0

276
00:12:28,269 --> 00:12:29,710
Y ahora miradlo abajo

277
00:12:29,710 --> 00:12:31,250
8 por 1

278
00:12:31,250 --> 00:12:33,389
4 por 5

279
00:12:33,389 --> 00:12:34,590
3 por 5

280
00:12:34,590 --> 00:12:35,009
El orbe

281
00:12:35,009 --> 00:12:35,990
2 por 5

282
00:12:35,990 --> 00:12:36,529
El orbe

283
00:12:36,529 --> 00:12:38,149
Muy bien

284
00:12:38,149 --> 00:12:38,870
El orbe

285
00:12:38,870 --> 00:12:41,350
Si ahora sigo esta serie

286
00:12:41,350 --> 00:12:43,610
¿Dónde van a aparecer aquí os números negativos?

287
00:12:44,029 --> 00:12:45,409
Al principio

288
00:12:45,409 --> 00:12:46,590
Aquí, ¿verdad?

289
00:12:46,889 --> 00:12:48,090
4 entre 2, menos 1

290
00:12:48,090 --> 00:12:49,529
¿Lo veis?

291
00:12:50,289 --> 00:12:51,309
Bueno, está aquí puesto

292
00:12:51,309 --> 00:12:52,570
Tampoco me matase

293
00:12:52,570 --> 00:12:53,529
¿Ves?

294
00:12:55,190 --> 00:12:56,090
¿Qué va a salir?

295
00:12:56,750 --> 00:12:57,590
¿Positivo o negativo?

296
00:12:57,690 --> 00:12:58,169
Negativo

297
00:12:58,169 --> 00:13:00,309
¿Vale?

298
00:13:00,669 --> 00:13:01,450
Por cierto

299
00:13:01,450 --> 00:13:04,629
¿Menos 1 por 5 será lo mismo que 5 por menos 1?

300
00:13:05,929 --> 00:13:06,129
Sí

301
00:13:06,129 --> 00:13:07,350
¿Se nos dice el factorismo?

302
00:13:07,850 --> 00:13:08,350
No, no, no

303
00:13:08,350 --> 00:13:10,110
En vez de los factores no alterar al producto

304
00:13:10,110 --> 00:13:10,789
Eso tiene un nombre

305
00:13:10,789 --> 00:13:14,370
Así que fijaros

306
00:13:14,370 --> 00:13:16,389
Con este ejemplo de cambiar o número de lado

307
00:13:16,389 --> 00:13:17,850
Y ver que no va a dar lo mismo

308
00:13:17,850 --> 00:13:19,610
Aunque estábamos con el signo

309
00:13:19,610 --> 00:13:21,789
Hemos comprobado que

310
00:13:21,789 --> 00:13:24,750
La multiplicación de números enteros

311
00:13:24,750 --> 00:13:25,730
Tiene la propiedad

312
00:13:25,730 --> 00:13:29,870
No siempre pasa eso

313
00:13:29,870 --> 00:13:31,370
¿Conocéis alguna operación

314
00:13:31,370 --> 00:13:32,990
Que no sea computativa?

315
00:13:34,250 --> 00:13:36,009
La división

316
00:13:36,009 --> 00:13:38,570
No es lo mismo dividir 8 entre 4

317
00:13:38,570 --> 00:13:40,769
Que 4 entre 8

318
00:13:40,769 --> 00:13:44,570
Alguna operación máis

319
00:13:44,570 --> 00:13:46,110
Que non tenga a propiedade computativa

320
00:13:46,110 --> 00:13:47,769
A resta

321
00:13:47,769 --> 00:13:49,190
O sea que

322
00:13:49,190 --> 00:13:51,889
Podemos dizer que a propiedade computativa

323
00:13:51,889 --> 00:13:53,809
A cumple a suma

324
00:13:53,809 --> 00:13:56,309
E a multiplicación

325
00:13:56,309 --> 00:13:57,850
E a última serie

326
00:13:57,850 --> 00:13:58,629
Que eu propongo

327
00:13:58,629 --> 00:14:01,690
En la hoja, agora que sabemos

328
00:14:01,690 --> 00:14:02,889
Que isto vai dar negativo

329
00:14:02,889 --> 00:14:04,049
É esta serie

330
00:14:04,049 --> 00:14:06,070
Aqui os observadores

331
00:14:06,070 --> 00:14:06,929
Ten que dar cuenta

332
00:14:06,929 --> 00:14:08,450
Menos 3 por 4

333
00:14:08,450 --> 00:14:11,809
y menos 12

334
00:14:11,809 --> 00:14:15,009
¿alguén sabe escribir ahí la serie?

335
00:14:17,009 --> 00:14:18,809
¿dicen que sabe escribir ahí la serie?

336
00:14:19,470 --> 00:14:19,750
no

337
00:14:19,750 --> 00:14:23,309
tú no puedes

338
00:14:23,309 --> 00:14:25,090
¿alguén más?

339
00:14:26,230 --> 00:14:26,490
¿tú?

340
00:14:26,490 --> 00:14:27,389
no, no

341
00:14:27,389 --> 00:14:32,590
vamos a escribirla

342
00:14:32,590 --> 00:14:34,830
los observadores, atentos

343
00:14:34,830 --> 00:14:36,490
menos 3 por 4

344
00:14:36,490 --> 00:14:42,940
¿Cuánto da menos 3 por 4?

345
00:14:43,080 --> 00:14:44,100
Menos 12

346
00:14:44,100 --> 00:14:49,840
Bueno, yo quería poner la serie

347
00:14:49,840 --> 00:14:51,659
Borra, borra

348
00:14:51,659 --> 00:14:53,500
La serie sin menos 12

349
00:14:53,500 --> 00:14:55,419
Perdón

350
00:14:55,419 --> 00:14:57,000
Yo

351
00:14:57,000 --> 00:14:59,759
Menos 12, así, grande, ¿vale?

352
00:14:59,960 --> 00:15:00,539
Ah, vale

353
00:15:00,539 --> 00:15:03,059
Menos 3 por 3

354
00:15:03,059 --> 00:15:05,460
Menos 9

355
00:15:05,460 --> 00:15:07,519
Menos 3 por 2

356
00:15:07,519 --> 00:15:09,860
Menos 6

357
00:15:09,860 --> 00:15:11,200
Menos 3 por 1

358
00:15:11,200 --> 00:15:14,120
Menos 3 por 0

359
00:15:14,120 --> 00:15:15,659
0

360
00:15:15,659 --> 00:15:17,519
E agora, quere?

361
00:15:19,440 --> 00:15:20,419
Fijaros como se ha hecho

362
00:15:20,419 --> 00:15:21,620
Menos 3 por 4

363
00:15:21,620 --> 00:15:22,559
Menos 3 por 3

364
00:15:22,559 --> 00:15:23,320
Menos 3 por 1

365
00:15:23,320 --> 00:15:24,019
Menos 3 por 0

366
00:15:24,019 --> 00:15:24,820
E agora que tocaría?

367
00:15:25,879 --> 00:15:26,899
Menos 3 por?

368
00:15:28,379 --> 00:15:30,460
Pero fijaros en la serie

369
00:15:30,460 --> 00:15:31,960
Aí que estamos haciendo?

370
00:15:31,960 --> 00:15:32,860
A revés

371
00:15:32,860 --> 00:15:33,879
A revés

372
00:15:33,879 --> 00:15:36,299
Que estamos haciendo?

373
00:15:36,299 --> 00:15:38,299
Estamos terminando

374
00:15:38,299 --> 00:15:42,419
Estamos sumando 3

375
00:15:42,419 --> 00:15:43,120
¿Verdad?

376
00:15:43,840 --> 00:15:44,259
¿Si o no?

377
00:15:45,320 --> 00:15:47,120
Porque en los cuadraditos que vimos

378
00:15:47,120 --> 00:15:48,220
Cuando la suma

379
00:15:48,220 --> 00:15:49,320
Menos 12 sería
