Walcom tae the video oan 
'Baseec Subtraction'.

Lat's think aneat some
'Baseec Addeetion' first.

Gif Ah said '4 plus 3'(4 + 3),
whit wid this mean?

Whit dis that make?

Weel, thaur's
2-3 waas that

we coud hae seen this.

We coud hae said, "Ah had 4 o sommit".

Lat's say that Ah had 4 circles, or

Ah had 4 lemons fer breakfast.

Sae, 1, 2, 3, 4 lemons fer breakfast.

N lat's say that Ah had
anither 3 lemons fer lunch.

1, 2, 3.

N sae ye coud see 4 + 3 aes

"Hou monie lemons hae Ah aw up?"

Ah'm eikin 3 tae 4.

Sae hou monie hae Ah aw up?

Weel, it's 1, 2, 3, 4, 5, 6, 7.

Sae Ah hae 7 lemons aw up.

Anither wa that we can see this

is we can draw oor 'nummer line'.

N Ah'l draw it in yelloch cause we'r -

Weel, thon's no wide enouch.

Ah'l darw it in yelloch,

cause we'r taukin aneat lemons.

Sae lat's say that that's oor nummer line.

N gif Ah stert at the nummer -

Lat me draw aw o the nummers.

0, 1, 2, 3, 4, 5, 6, 7.

Sae ye coud think o this aes sayin,

Weel, we'r oan the nummer line.

We stert at the nummer 4, Aye?

(thon's 4)

N we'r eikin 3 tae it.

Sae we'l increase
alang the nummer line bi 3.

Sae we'l gae 1, 2, 3 - n ye get tae 7.

Sae ye can say,

"Gif Ah hae 4, n ah get
3 mair, than ah get 7".

Or, "Gif Ah increase
4 bi 3, than Ah get 7 n aw".

Sae whit's 'subtraction' the nou?

(Cause thon's whit this video's aneat.)

Ah shidna wast oor time
talkin aneat addition.

Sae lat's tak the exaumple o
4 minus 3 (4 -3).

Whit's this the sam aes?

Lat me chynge colours,
juist tae keep things interesting.

Sae whit's 4 - 3?

Subtraction -or 'minus' -
is the oposite o addeetion.

Sae in addeetion,
ye'r dae sommit mair.

Ye'r eikin.

(Ah dinnae want tae use the word 'eikin'

fer tae define 'addeetion' -

bit thon's whit ye'r daein.)

Ah haed 4 lemons, an than ah haed 3 mair.

In 'subtraction', ye'r takin thaim awa.

Sae in this exaumple,
gif Ah stertit wi 4 lemons -

Lat's say that Ah haed
4 lemons oan a plate.

Gif Ah'm subtractin 3 -

Gif Ah'm sayin minus 3,
