1
00:00:00,730 --> 00:00:03,457
Nan videyo sa a mwen vle familyarize tèt nou

2
00:00:03,457 --> 00:00:04,768
ak negatif anpil moun.

3
00:00:04,768 --> 00:00:07,564
Et aprann tou yon ti kras sou kòmann yo fè nou ajoute Et retire yo.

4
00:00:07,564 --> 00:00:09,326
Lè ou fèk kontre yo,

5
00:00:09,326 --> 00:00:11,612
yo sanble nan gwo basen byen fon Et mistik bagay sa a.

6
00:00:11,612 --> 00:00:14,769
Lè nou fèk konte bagay, nou ap konte moun pozitif.

7
00:00:14,769 --> 00:00:17,346
Sa fè yon bann negatif menm mechan?

8
00:00:17,346 --> 00:00:20,835
Men, lè nou panse osijè de sa, ou kapab byen ont rencontré

9
00:00:20,835 --> 00:00:22,905
numéros negatif nan lavi chak jou ou.

10
00:00:22,905 --> 00:00:25,195
Et, kite m' sèlman fè ou kèk egzanp.

11
00:00:25,195 --> 00:00:26,412
Se konsa, anvan sa, m' ap moutre a, jeneral lide an se

12
00:00:26,412 --> 00:00:30,674
anpil negatif se yon nimewo mwens ke zewo.

13
00:00:30,674 --> 00:00:34,839
Mwens ke zewo.

14
00:00:34,839 --> 00:00:37,191
Et si ki sanble lòt Et résumé pou nou la a,

15
00:00:37,191 --> 00:00:39,851
an n jis panse osijè de li nan yon koup diferan contextes.

16
00:00:39,851 --> 00:00:45,251
Si mwen gen... Si nou ap mezire tanperati a...

17
00:00:45,251 --> 00:00:47,114
(e li kapab nan Celsius ou Farenheit,

18
00:00:47,114 --> 00:00:49,881
Men, Ann èspere jis di nou ap mezire li nan Celsius),

19
00:00:49,881 --> 00:00:51,878
Se konsa se pou m' fè yon ti kal

20
00:00:51,878 --> 00:00:53,707
pou nou ka mezire tanperati a sou.

21
00:00:53,707 --> 00:00:57,099
Se konsa nou di ke sa se 0° Celsius

22
00:00:57,099 --> 00:01:02,909
sa se 1° Celsius, 2° Celsius, 3° Celsius.

23
00:01:02,924 --> 00:01:05,817
Koulye a, an n di li se yon jou vrèman fè frèt

24
00:01:05,817 --> 00:01:10,296
Et, ki aktyèlman 3° Celsius.

25
00:01:10,296 --> 00:01:12,004
Ak yon moun ki te pwedi a tan kap vini

26
00:01:12,004 --> 00:01:16,976
di ou ke li pwal gen 4° plus jou kap vini a.

27
00:01:16,976 --> 00:01:21,502
Se konsa jan frèt pral rive? Ki jan ou kapab repwezante coldness sa?

28
00:01:21,502 --> 00:01:25,126
Men, si li apèn 1° plus li ta nan 2°,

29
00:01:25,126 --> 00:01:26,874
Men, nou konnen nou gen pou ale 4° plus.

30
00:01:26,874 --> 00:01:32,068
Si nou a 2° plus, nou ta gen nan 1°.

31
00:01:32,068 --> 00:01:35,311
Si nou a 3° plus, nou ta gen nan 0°.

32
00:01:35,311 --> 00:01:38,453
Men, 3° pa suffisante, nou dwe genyen 4° plus,

33
00:01:38,453 --> 00:01:43,965
Se konsa nou gen aktyèlman ale yon lòt anba zewo.

34
00:01:43,965 --> 00:01:50,416
Et sa 1 pi ba pase 0 nou rele sa "1 negatif".

35
00:01:50,416 --> 00:01:52,907
Se konsa, ou kapab ti jan wè sa liy nimewo

36
00:01:52,907 --> 00:01:57,029
menm jan ou fè bò dwat la zewo yo ogmante nan valè pozitif,

37
00:01:57,029 --> 00:02:04,207
menm jan ou al sou bò gòch la zewo ou pwal gen-1,-2,-3.

38
00:02:04,207 --> 00:02:07,301
Et, ou pral fè en fonction sou kijan ou panse osijè de li-

39
00:02:07,301 --> 00:02:09,948
ou pral fè gen pi gwo nimewo negatif.

40
00:02:09,948 --> 00:02:15,372
Men, mwen vle fè sa trè klè:-3, ki se MWENS ke-1.

41
00:02:15,372 --> 00:02:19,488
Pa gen mwens chalè nan lè a nan-3 ° pase nan-1 °.

42
00:02:19,488 --> 00:02:23,329
Li plus---pa gen mwens tanperati.

43
00:02:23,329 --> 00:02:39,824
Se pou m' sèlman fè li trè klè:-100 pi piti anpil pase-1.

44
00:02:39,824 --> 00:02:41,913
Ou ka chèche nan 100 Et ou te ka gade nan 1 Et

45
00:02:41,913 --> 00:02:45,094
reyaksyon wo sak trip ou peut être 100 pi gwo pase 1.

46
00:02:45,094 --> 00:02:46,272
Men, lè ou panse osijè de sa,

47
00:02:46,272 --> 00:02:48,849
-100 vle di pa gen yon mank de yon bagay.

48
00:02:48,849 --> 00:02:52,304
-100: Si se-100 ° pa gen yon mank de solèy.

49
00:02:52,304 --> 00:02:55,737
Se konsa pa gen pi rèd chalè isit la pase si nou te gen-1 °.

50
00:02:55,737 --> 00:02:57,493
Kite m ba ou yon lòt egzanp.

51
00:02:57,493 --> 00:03:11,264
An n di nan kont labank m' jòdi a mwen gen $10.

52
00:03:11,264 --> 00:03:13,114
Koulye a, an n di mwen ale la

53
00:03:13,114 --> 00:03:14,949
(paske m santi m byen osijè de m $10),

54
00:03:14,949 --> 00:03:21,426
Et, an n di mwen ale, pase $30.

55
00:03:21,426 --> 00:03:22,735
Et, for the sake of chire pit

56
00:03:22,735 --> 00:03:24,275
an n di mwen gen yon bank anpil likid

57
00:03:24,275 --> 00:03:26,861
Lè sa a, yonn pou m ' depanse plis lajan mwen gen

58
00:03:26,861 --> 00:03:28,354
(Et sa yo aktyèlman ekziste!).

59
00:03:28,354 --> 00:03:30,422
Se konsa, mwen pase $30.

60
00:03:30,422 --> 00:03:32,907
Se konsa m' kont anbank sak sanble?

61
00:03:32,907 --> 00:03:35,564
Se pou m' trase yon liy nimewo isit la.

62
00:03:35,564 --> 00:03:37,839
Apre sa, nou ka deja gen yon repons intuitive:

63
00:03:37,839 --> 00:03:43,284
Mwen pral dwe bank la yon lajan.

64
00:03:43,284 --> 00:03:47,130
Denmen, ki sa ki kont labank m?

65
00:03:47,130 --> 00:03:51,642
Nou te imedyatman di: "si m gen $10 Et mwen pase $30,

66
00:03:51,642 --> 00:03:54,219
pa gen $20 sa yo te gen pou leve soti yon kote."

67
00:03:54,219 --> 00:03:56,489
Et sa $20 ap soti nan bank lan.

68
00:03:56,489 --> 00:03:59,119
Se konsa mwen pral dwe $20, bank lan.

69
00:03:59,119 --> 00:04:00,789
Poutèt sa, m' kont anbank, nan

70
00:04:00,789 --> 00:04:07,199
pou montre konbyen m, mwen te kapab di $10 - $30-$20.

71
00:04:07,199 --> 00:04:13,345
Se konsa nan kont bank mwen denmen, mwen pral gen-$20.

72
00:04:13,345 --> 00:04:18,075
Se konsa, si mwen di: mwen gen-$20, sa vle di mwen dwe bank lan.

73
00:04:18,075 --> 00:04:19,357
---Mwen pa bezwen sa.

74
00:04:19,357 --> 00:04:20,946
Se pa sa sèlman, èske mwen pa gen anyen, mwen pa dwe yon bagay.

75
00:04:20,946 --> 00:04:22,535
Li pwal nan inverse.

76
00:04:22,535 --> 00:04:25,589
Isit la, mwen gen yon bagay ase...

77
00:04:25,589 --> 00:04:29,228
Si m $10 nan kont labank m' vle di nan bank lan fè prete m $10.

78
00:04:29,228 --> 00:04:31,817
M fè $10 sa mwen ka itilize pou ale pase. / kè m boule m.

79
00:04:31,817 --> 00:04:33,390
Koulye a, tout de yon soudaine mwen dwe bank lan.

80
00:04:33,390 --> 00:04:34,963
Mwen te al lòt bò.

81
00:04:34,963 --> 00:04:36,778
Si nou itilize yon liy nimewo isit la

82
00:04:36,778 --> 00:04:38,593
li ta dwe fè, plis konprann.

83
00:04:38,593 --> 00:04:39,832
Se poutèt sa se 0.

84
00:04:39,832 --> 00:04:43,347
M ap konmanse ak $10,

85
00:04:43,347 --> 00:04:47,417
Et depans $30 vle di m ap fè mache 30 sou bò gòch.

86
00:04:47,417 --> 00:04:49,848
Si mwen jwe 10 mache sou bò gòch---

87
00:04:49,848 --> 00:04:52,804
Si mwen sèlman pase $10 m ap tounen nan $0.

88
00:04:52,804 --> 00:04:56,829
Si mwen pase yon lòt $10, m' ap fè nan-$10.

89
00:04:56,829 --> 00:05:02,208
Si mwen pase yon lòt $10 Apre sa, m' ap nan-$20.

90
00:05:02,208 --> 00:05:04,483
Se konsa, chak de distans sa yo, m' ap pase $10 mwen ki pwal nan $0.

91
00:05:04,483 --> 00:05:06,759
Yon lòt $10 mwen ki pwal nan-$10.

92
00:05:06,759 --> 00:05:09,754
Yon lòt $10 mwen ki pwal nan-$20.

93
00:05:09,754 --> 00:05:13,144
Se poutèt sa a an antye distans isit la se konbyen mwen te pase.

94
00:05:13,144 --> 00:05:17,270
Mwen te pase $30.

95
00:05:17,270 --> 00:05:20,398
Se konsa lide jeneral an lè ou pase, ou si ou retire,

96
00:05:20,398 --> 00:05:23,327
ou obtenir plus, ou ta deplase pou sou bò gòch.

97
00:05:23,327 --> 00:05:24,803
Anpil moun la ta gen pi piti.

98
00:05:24,803 --> 00:05:27,229
E nou konnen koulye a yo ka jwenn menm pi piti 0.

99
00:05:27,229 --> 00:05:31,604
Yo kapab ale pou-1,-2---yo ka menm al pou-1.5,-1.6.

100
00:05:31,604 --> 00:05:34,948
La pi byen toujou negatif, plis ou pèdi.

101
00:05:34,948 --> 00:05:37,268
Si ou gen ajout, si mwen ale, pran m' lajan taks sou chèk

102
00:05:37,268 --> 00:05:41,389
Mwen pral fè mouvman pou dwa liy nimewo a.

103
00:05:41,389 --> 00:05:43,058
Koulye a, ak pye, sa

104
00:05:43,058 --> 00:05:46,082
an n jis fè kèk plis nan matematik pwoblèm.

105
00:05:46,082 --> 00:05:52,317
Kisa sa vle di, si nou te gen pou di...

106
00:05:52,317 --> 00:05:56,474
An n pale, 3-4.

107
00:05:56,474 --> 00:05:57,710
Se konsa yon fwa ankò,

108
00:05:57,710 --> 00:06:00,193
sa se exactement sitiyasyon nou te fè ak tanperati a.

109
00:06:00,193 --> 00:06:01,944
Nou ap konmanse ak 3 Et nou ap soustrayant 4,

110
00:06:01,944 --> 00:06:03,695
Se poutèt sa, nou pral pou yo avanse 4 sou bò gòch.

111
00:06:03,695 --> 00:06:05,854
Nou ale 1, 2, 3, 4.

112
00:06:05,854 --> 00:06:10,417
Ki jwenn nou pou-1.

113
00:06:10,417 --> 00:06:11,767
Lè ou konmanse fè sa

114
00:06:11,767 --> 00:06:13,934
ou vrèman konprann ki yon negatif nimewo mwayen.

115
00:06:13,934 --> 00:06:15,843
Mwen reyèlman ankouraje w visualiser liy nimewo a

116
00:06:15,843 --> 00:06:17,752
Et vrèman deplase nan men l' sou en

117
00:06:17,752 --> 00:06:19,961
èske ou gen ajout ou soustrayant.

118
00:06:19,961 --> 00:06:21,236
An n fè kèk ankò.

119
00:06:21,236 --> 00:06:27,848
An n di mwen gen 2-8

120
00:06:27,848 --> 00:06:30,552
(e nou ap panse osijè de lòt fason pou fè sa a nan pwochen vidéos),

121
00:06:30,552 --> 00:06:33,612
Men, yon fwa ankò, ou jis vle fè liy nimewo a.

122
00:06:33,612 --> 00:06:35,083
Ou gen yon 0 isit la.

123
00:06:35,083 --> 00:06:38,729
Nan (kite m' trase espacement a yon ti kras).

124
00:06:38,729 --> 00:06:42,032
Nou gen 0 isit la... nan 1... 2.

125
00:06:42,032 --> 00:06:43,891
Si nou gen soustrayant 8,

126
00:06:43,891 --> 00:06:47,043
sa vle di nou pwal pou yo avanse 8 sou bò gòch.

127
00:06:47,043 --> 00:06:50,993
Se konsa nou pral fè bò gòch, 2 sou bò gòch 1.

128
00:06:50,993 --> 00:06:53,036
Se konsa, nou te ale 2 sou bò gòch pou ale 0.

129
00:06:53,036 --> 00:06:55,080
Nou gen pou yo avanse ki kantite ankò sou bò gòch?

130
00:06:55,080 --> 00:06:56,961
Nou deja te deplase 2 sou bò gòch,

131
00:06:56,961 --> 00:06:59,010
pou jwenn pou 8, nou gen pou yo avanse 6 plis sou bò gòch.

132
00:06:59,010 --> 00:07:07,396
Se konsa nou pral gen pou yo avanse 1-2-3-4-5-6 ankò sou bò gòch.

133
00:07:07,396 --> 00:07:09,106
Men, kote sa pwal fè nou?

134
00:07:09,106 --> 00:07:10,074
Men, nou te nan 0.

135
00:07:10,074 --> 00:07:18,706
Sa se-1,-2,-3,-4,-5,-6.

136
00:07:18,706 --> 00:07:24,310
Se konsa, 2-8 se-6.

137
00:07:24,310 --> 00:07:26,540
2-2 ki ta 0.

138
00:07:26,540 --> 00:07:29,633
Lè w ap soustrayant 8 ou ap soustrayant 6 yon lòt.

139
00:07:29,633 --> 00:07:33,366
Se konsa nou ale nan-6, nou pase 6 pi ba pase 0.

140
00:07:33,366 --> 00:07:34,994
Pou m' fè youn nan ekzanp plis.

141
00:07:34,994 --> 00:07:36,562
(Et sa a pral yon ti kras mwens classiques

142
00:07:36,562 --> 00:07:38,807
Men, li pral fè sans).

143
00:07:38,807 --> 00:07:43,976
Ann pran... (e mwen pwal fè sa nan yon nouvo koulè)...

144
00:07:43,976 --> 00:07:47,870
Kite m' wete-4-2.

145
00:07:47,870 --> 00:07:49,439
Se konsa nou ap kòmanse nan anpil negatif

146
00:07:49,439 --> 00:07:51,009
Apre sa, lè sa a nou ap soustrayant pou sa.

147
00:07:51,009 --> 00:07:56,808
Koulye a, si sa semble ki pa klè jis sonje liy nimewo a!

148
00:07:56,838 --> 00:07:59,680
Se poutèt sa se isit-0.

149
00:07:59,680 --> 00:08:07,015
Sa se-1,-2,-3,-4. Se konsa, sa se kote nou ap kòmanse.

150
00:08:07,015 --> 00:08:09,279
Kounye a nou pwal retire 2 de-4,

151
00:08:09,279 --> 00:08:11,543
Se poutèt sa, nou pral pou yo avanse 2 sou bò gòch.

152
00:08:11,543 --> 00:08:15,387
Se konsa, si nou retire 1 nou ap fè nan-5.

153
00:08:15,387 --> 00:08:21,723
Si nou retire yon lòt 1 nou pwal gen nan-6.

154
00:08:21,723 --> 00:08:23,332
Se poutèt sa se-6.

155
00:08:23,332 --> 00:08:24,748
An n fè yon lòt bagay enteresan.

156
00:08:24,748 --> 00:08:30,266
An n kòmanse nan-3... Ann di nou gen-3.

157
00:08:30,266 --> 00:08:34,261
Olye ke yo soustrayant yon bagay sòti de sa, an n ajoute 2.

158
00:08:34,261 --> 00:08:36,562
Se konsa kote ta sa a mete nou sou liy nimewo a?

159

00:08:46,760 --> 00:08:47,969
ou vin-1.

164

Ou fè mouvman 2 pou dwa.

165
