1
00:00:00,605 --> 00:00:07,560
We need tae calculate 9.005 minus 3.6,
or we coud seeit aes

2
00:00:07,560 --> 00:00:13,067
9 n 5 thoosants
minus 3 n 6 tents.

3
00:00:13,067 --> 00:00:15,800
Whaniver ye dae ae subtractin deceemals proablem,
the maist important thing,

4
00:00:15,800 --> 00:00:18,063
n this is true whan ye'r eikin deceemals n aw,

5
00:00:18,078 --> 00:00:20,383
is that ye hae tae line the deceemals up.

6
00:00:20,383 --> 00:00:31,877
Sae 9.005 minus 3.6.

7
00:00:31,877 --> 00:00:35,283
Sae we'v lined the decemals up,
n nou we'r readie tae subtract.

8
00:00:36,557 --> 00:00:38,077
Nou we can subtract.

9
00:00:38,077 --> 00:00:39,233
Sae we stert up here.

10
00:00:39,233 --> 00:00:41,533
We hae 5 minus nawthing.

11
00:00:41,533 --> 00:00:44,162
Ye coud imagen 3.6,
or 3 n 6 tents.

12
00:00:44,162 --> 00:00:47,867
We coud eik twa zeros richt here,
n it wid be the same thing aes

13
00:00:47,867 --> 00:00:52,110
3 n 600 thoosants,
the same aes 6 tents.

14
00:00:52,110 --> 00:00:55,055
N whan ye luik at it that waa,
ye'd say, "O.K., 5 minus 0 is nawthing,

15
00:00:55,055 --> 00:00:56,757
n ye juist sceeve ae 5 here".

16
00:00:56,757 --> 00:00:58,590
Or ye coud'v said,
gif thaur's nawthin there,

17
00:00:58,590 --> 00:01:00,743
It woud hae been
5 minus nawthing is 5.

18
00:01:00,743 --> 00:01:04,147
Than ye hae 0 minus 0,
n that's 0.

19
00:01:04,147 --> 00:01:07,600
N than ye hae ae 0 minus 6.

20
00:01:07,600 --> 00:01:09,970
N ye canna sutract 6 fae 0.

21
00:01:09,970 --> 00:01:12,678
Sae we need tae get sommit
intae this space here,

22
00:01:12,678 --> 00:01:15,203
n whit we'r baseeclie gaun tae dae
is tae regroop.

23
00:01:15,203 --> 00:01:20,234
We'r gaun tae tak ae 1 fae the 9,
sae lat's dae that.

24
00:01:20,234 --> 00:01:24,654
Sae lats tak ae 1 fae the 9,
sae it becomes aen 8.

25
00:01:24,654 --> 00:01:26,307
N we need tae dae sommit wi that 1.

26
00:01:26,307 --> 00:01:28,933
We'r gaun tae put it in the tents steid.

27
00:01:28,933 --> 00:01:32,147
Mynd ye, yin hale is the sam aes 10 tents.

28
00:01:32,147 --> 00:01:34,053
This is the tents steid.

29
00:01:34,053 --> 00:01:36,907
Sae than this wil become 10.

30
00:01:36,907 --> 00:01:38,972
Somtimes it's said that ye'r
borroin the 1,

31
00:01:38,972 --> 00:01:41,200
but ye'r realie takin it,
n ye'r realie takin 10

32
00:01:41,200 --> 00:01:43,560
fae the steid oan ye'r cair.

33
00:01:43,560 --> 00:01:46,812
Sae yin hale is 10 tents,
we'r in the tents steid.

34
00:01:46,812 --> 00:01:49,348
Sae ye hae 10 minus 6.

35
00:01:49,348 --> 00:01:50,290
Lat me switch colours.

36
00:01:50,290 --> 00:01:52,433
10 minus 6 is 4.

37
00:01:52,433 --> 00:01:55,071
Ye hae ye'r deceemal richt there,
n than ye hae

38
00:01:55,071 --> 00:01:58,313
8 minus 3 is 5.

39
00:01:58,313 --> 00:02:06,403
Sae 9.005 minus 3.6 is 5.405.
