Walcom tae the video oan 
'Baseec Subtraction'.

00:00:05.623 --> 00:00:10.330
Lat's think aneat some
'Baseec Addeetion' first.

00:00:10.330 --> 00:00:19.155
Gif Ah said '4 plus 3'(4 + 3),
whit wid this mean?

00:00:19.155 --> 00:00:20.690
Whit dis that make?

00:00:20.690 --> 00:00:22.016
Weel, thaur's

00:00:22.928 --> 00:00:24.301
We coud hae said, "Ah had 4 o sommit".

00:00:24.301 --> 00:00:27.576
Lat's say that Ah had 4 circles, or

Ah had 4 lemons fer breakfast.

00:00:29.960 --> 00:00:36.170
Sae, 1, 2, 3, 4 lemons fer breakfast.

1, 2, 3.

00:00:43.584 --> 00:00:45.582
N sae ye coud see 4 + 3 aes

00:00:45.582 --> 00:00:47.796
"Hou monie lemons hae Ah aw up?"

00:00:47.796 --> 00:00:49.640
Ah'm eikin 3 tae 4.

00:00:49.640 --> 00:00:50.843
Sae hou monie hae Ah aw up?

00:00:50.843 --> 00:00:55.196

Sae Ah hae 7 lemons aw up.

00:00:59.180 --> 00:01:01.030
Anither wa that we can see this

00:01:01.030 --> 00:01:04.060
is we can draw oor 'nummer line'.

00:01:04.060 --> 00:01:07.230
N Ah'l draw it in yelloch cause we'r -

00:01:07.230 --> 00:01:09.494
Weel, thon's no wide enouch.

Ah'l darw it in yelloch,

00:01:10.553 --> 00:01:13.597
cause we'r taukin aneat lemons.

00:01:13.597 --> 00:01:18.150
Sae lat's say that that's oor nummer line.

00:01:18.150 --> 00:01:19.678
N gif Ah stert at the nummer -

00:01:19.678 --> 00:01:21.702
Lat me draw aw o the nummers.

00:01:21.702 --> 00:01:32.010
0, 1, 2, 3, 4, 5, 6, 7.

00:01:32.010 --> 00:01:34.275
Sae ye coud think o this aes sayin,

00:01:34.275 --> 00:01:35.354
Weel, we'r oan the nummer line.

00:01:35.354 --> 00:01:37.872
We stert at the nummer 4, Aye?

00:01:37.872 --> 00:01:39.120
(thon's 4)

00:01:39.120 --> 00:01:40.700
N we'r eikin 3 tae it.

00:01:40.700 --> 00:01:44.170
Sae we'l increase
alang the nummer line bi 3.

00:01:44.170 --> 00:01:48.650
Sae we'l gae 1, 2, 3 - n ye get tae 7.

00:01:48.650 --> 00:01:50.012
Sae ye can say,

00:01:50.012 --> 00:01:51.996
"Gif Ah hae 4, n ah get
3 mair, than ah get 7".

00:01:51.996 --> 00:01:57.027
Or, "Gif Ah increase
4 bi 3, than Ah get 7 n aw".

00:01:57.027 --> 00:01:59.340
Sae whit's 'subtraction' the nou?

00:01:59.340 --> 00:02:00.450
(Cause thon's whit this video's aneat.)

00:02:00.450 --> 00:02:01.488
Ah shidna wast oor time

Sae whit's 4 - 3?

00:02:18.860 --> 00:02:22.803
Subtraction -or 'minus' -
is the oposite o addeetion.

00:02:22.803 --> 00:02:26.266
Sae in addeetion,
ye'r dae sommit mair.

00:02:28.322 --> 00:02:29.676
fer tae define 'addeetion' -

00:02:29.676 --> 00:02:31.030
