00:00:00.605 --> 00:00:07.560
We need tae calculate 9.005 minus 3.6,
or we coud seeit aes

00:00:07.560 --> 00:00:13.067
9 n 5 thoosants
minus 3 n 6 tents.

00:00:13.067 --> 00:00:15.800
Whaniver ye dae ae subtractin deceemals proablem,
the maist important thing,

00:00:15.800 --> 00:00:18.063
n this is true whan ye'r eikin deceemals n aw,

00:00:18.078 --> 00:00:20.383
is that ye hae tae line the deceemals up.

00:00:20.383 --> 00:00:31.877
Sae 9.005 minus 3.6.

00:00:31.877 --> 00:00:35.283
Sae we'v lined the decemals up,
n nou we'r readie tae subtract.

00:00:36.557 --> 00:00:38.077
Nou we can subtract.

00:00:38.077 --> 00:00:39.233
Sae we stert up here.

00:00:39.233 --> 00:00:41.533
We hae 5 minus nawthing.

00:00:41.533 --> 00:00:44.162
Ye coud imagen 3.6,
or 3 n 6 tents.

00:00:44.162 --> 00:00:47.867
We coud eik twa zeros richt here,
n it wid be the same thing aes

00:00:47.867 --> 00:00:52.110
3 n 600 thoosants,
the same aes 6 tents.

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,

00:00:55.055 --> 00:00:56.757
n ye juist sceeve ae 5 here".

00:00:56.757 --> 00:00:58.590
Or ye coud'v said,
gif thaur's nawthin there,

00:00:58.590 --> 00:01:00.743
It woud hae been
5 minus nawthing is 5.

00:01:00.743 --> 00:01:04.147
Than ye hae 0 minus 0,
n that's 0.

00:01:04.147 --> 00:01:07.600
N than ye hae ae 0 minus 6.

00:01:07.600 --> 00:01:09.970
N ye canna sutract 6 fae 0.

00:01:09.970 --> 00:01:12.678
Sae we need tae get sommit
intae this space here,

00:01:12.678 --> 00:01:15.203
n whit we'r baseeclie gaun tae dae
is tae regroop.

00:01:15.203 --> 00:01:20.234
We'r gaun tae tak ae 1 fae the 9,
sae lat's dae that.

00:01:20.234 --> 00:01:24.654
Sae lats tak ae 1 fae the 9,
sae it becomes aen 8.

00:01:24.654 --> 00:01:26.307
N we need tae dae sommit wi that 1.

00:01:26.307 --> 00:01:28.933
We'r gaun tae put it in the tents steid.

00:01:28.933 --> 00:01:32.147
Mynd ye, yin hale is the sam aes 10 tents.

00:01:32.147 --> 00:01:34.053
This is the tents steid.

00:01:34.053 --> 00:01:36.907
Sae than this wil become 10.

00:01:36.907 --> 00:01:38.972
Somtimes it's said that ye'r
borroin the 1,

00:01:38.972 --> 00:01:41.200
but ye'r realie takin it,
n ye'r realie takin 10

00:01:41.200 --> 00:01:43.560
fae the steid oan ye'r cair.

00:01:43.560 --> 00:01:46.812
Sae yin hale is 10 tents,
we'r in the tents steid.

00:01:46.812 --> 00:01:49.348
Sae ye hae 10 minus 6.

00:01:49.348 --> 00:01:50.290
Lat me switch colours.

00:01:50.290 --> 00:01:52.433
10 minus 6 is 4.

00:01:52.433 --> 00:01:55.071
Ye hae ye'r deceemal richt there,
n than ye hae

00:01:55.071 --> 00:01:58.313
8 minus 3 is 5.

00:01:58.313 --> 00:02:06.403
Sae 9.005 minus 3.6 is 5.405.
