Subtractin Deceemals

We need tae calculate 9.005 minus 3.6,
or we coud seeit aes

9 n 5 thoosants
minus 3 n 6 tents.

Whaniver ye dae ae subtractin deceemals proablem,
the maist important thing,

n this is true whan ye'r eikin deceemals n aw,

is that ye hae tae line the deceemals up.

Sae 9.005 minus 3.6.

Sae we'v lined the decemals up,
n nou we'r readie tae subtract.

Nou we can subtract.

Sae we stert up here.

We hae 5 minus nawthing.

Ye coud imagen 3.6,
or 3 n 6 tents.

We coud eik twa zeros richt here,
n it wid be the same thing aes

3 n 600 thoosants,
the same aes 6 tents.

N whan ye luik at it that waa,
ye'd say, "O.K., 5 minus 0 is nawthing,

n ye juist sceeve ae 5 here".

Or ye coud'v said,
gif thaur's nawthin there,

It woud hae been
5 minus nawthing is 5.

Than ye hae 0 minus 0,
n that's 0.

N than ye hae ae 0 minus 6.

N ye canna sutract 6 fae 0.

Sae we need tae get sommit
intae this space here,

n whit we'r baseeclie gaun tae dae
is tae regroop.

We'r gaun tae tak ae 1 fae the 9,
sae lat's dae that.

Sae lats tak ae 1 fae the 9,
sae it becomes aen 8.

N we need tae dae sommit wi that 1.

We'r gaun tae put it in the tents steid.

Mynd ye, yin hale is the sam aes 10 tents.

This is the tents steid.

Sae than this wil become 10.

Somtimes it's said that ye'r
borroin the 1,

but ye'r realie takin it,
n ye'r realie takin 10

fae the steid oan ye'r cair.

Sae yin hale is 10 tents,
we'r in the tents steid.

Sae ye hae 10 minus 6.

Lat me switch colours.

10 minus 6 is 4.

Ye hae ye'r deceemal richt there,
n than ye hae

8 minus 3 is 5.

Sae 9.005 minus 3.6 is 5.405.
