### matamataig---àireamheachd

Posted:

**Mon Jan 20, 2020 6:59 pm**Here is my understanding how how arithmetic (àireamheachd) works in Gaelic.

I’ve given statements, commands, and questions.

I’d be very grateful for any and all comments and corrections!

To say “What does…make?”, use “Dè tha…a’ dèanamh?”

To say “What does…equal?”, or “What is…equal to?”, use “Cò ris a tha…co-ionnan?”

To say “…equals…” or “…is equal to…”, use “Tha…co-ionnan ri…"

agus = and

air a chur ri... = plus, added to (NB, ri does not lenite, e.g. co-ionnan ri trì = equal to 3)

Tha aon agus dhà a’ dèanamh (co-ionnan ri) trì = 1 and 2 makes (equals/is equal to) 3.

(NB I prefer to avoid using adjacent numbers in "Tha aon agus dhà trì" = 1 and 2 is 3)

Tha aon air a chur ri dhà a’ dèanamh (co-ionnan ri) trì = 1 added to 2 makes (equals/is equal to) 3.

Aon agus dhà! = One and two!

Cuir aon ri dhà! = Add 1 and 2!

Dè tha aon agus (air a chur ri) dhà a’ dèanamh? = What does 1 and (plus, added to) 2 make?

Cò ris a tha aon agus (air a chur ri) dhà co-ionnan? = What does 1 and (plus, added to) 2 equal?

bho = from (does lenite, e.g. bho thrì = from 3)

air a thoirt air falbh bho... = subtracted from, taken away from...

àicheil trì = negative (minus) 3 (i.e. less than zero)

(mìonas exists but seems a fudge to me, and grammatically strange: trì mìonas dhà---is it a verb or preposition?)

(maybe mìonas is used in algebra: x - y spoken as “x mìonas y”?)

Tha dhà bho thrì a’ dèanamh (co-ionnan ri) aon. = 2 from 3 makes (is equal to) 1.

Tha dhà air a thoirt air falbh bho thrì a’ dèanamh (co-ionnan ri) aon = 2 subtracted from 3 makes (is equal to) 1.

Thoir dhà air falbh bho thrì! = Take away/subtract 2 from 3! (I think “air falbh” is riatanach here, so can’t just use bho)

Dè tha trì air a thoirt air falbh bho thrì a’ dèanamh aon = What does 2 subtracted from 3 make?

Cò ris a tha dhà air a thoirt air falbh bho thrì co-ionnan? = What does 2 subtracted from 3 equal?

air iomadachadh le... = multiplied by (le does not lenite)

uiread = times, as in “trì uiread cho mòr ri sin” = three times as big as that

Tha dhà air iomadachadh le trì a’ dèanamh (co-ionnan ri) sia = 2 multiplied by 3 makes (equals/is equal to) 6.

Iomadaich dhà le trì! = Multiply 2 and 3!

Dè tha dhà air iomadachahd le trì a’ dèanamh? = What does 2 multiplied by 3 make?

Cò leis a tha dhà air iomadachadh le trì co-ionnan? = What does 2 mutiplied by 3 equal?

air a roinn le... = divided by (le does not lenite)

Tha sia air a roinn le trì a’ dèanamh (co-ionnan ri) dhà = 6 divided by 2 makes (is equal to) 2.

Roinn sia le trì! = Divide 6 by 3!

Dè tha sia air a roinn le trì a’ dèanamh? = What does 6 divided by 3 make?

Cò ris a tha sia air a roinn le trì co-ionnan? = What does 6 divided by 3 equal?

I think that covers about everything. Any improvements, additions, comments, corrections….welcome!

I’ve given statements, commands, and questions.

I’d be very grateful for any and all comments and corrections!

To say “What does…make?”, use “Dè tha…a’ dèanamh?”

To say “What does…equal?”, or “What is…equal to?”, use “Cò ris a tha…co-ionnan?”

To say “…equals…” or “…is equal to…”, use “Tha…co-ionnan ri…"

**Addition/Plus = Cur ris, agus**agus = and

air a chur ri... = plus, added to (NB, ri does not lenite, e.g. co-ionnan ri trì = equal to 3)

Tha aon agus dhà a’ dèanamh (co-ionnan ri) trì = 1 and 2 makes (equals/is equal to) 3.

(NB I prefer to avoid using adjacent numbers in "Tha aon agus dhà trì" = 1 and 2 is 3)

Tha aon air a chur ri dhà a’ dèanamh (co-ionnan ri) trì = 1 added to 2 makes (equals/is equal to) 3.

Aon agus dhà! = One and two!

Cuir aon ri dhà! = Add 1 and 2!

Dè tha aon agus (air a chur ri) dhà a’ dèanamh? = What does 1 and (plus, added to) 2 make?

Cò ris a tha aon agus (air a chur ri) dhà co-ionnan? = What does 1 and (plus, added to) 2 equal?

**Subtraction/Minus = Toirt air Falbh (bho), bho**bho = from (does lenite, e.g. bho thrì = from 3)

air a thoirt air falbh bho... = subtracted from, taken away from...

àicheil trì = negative (minus) 3 (i.e. less than zero)

(mìonas exists but seems a fudge to me, and grammatically strange: trì mìonas dhà---is it a verb or preposition?)

(maybe mìonas is used in algebra: x - y spoken as “x mìonas y”?)

Tha dhà bho thrì a’ dèanamh (co-ionnan ri) aon. = 2 from 3 makes (is equal to) 1.

Tha dhà air a thoirt air falbh bho thrì a’ dèanamh (co-ionnan ri) aon = 2 subtracted from 3 makes (is equal to) 1.

Thoir dhà air falbh bho thrì! = Take away/subtract 2 from 3! (I think “air falbh” is riatanach here, so can’t just use bho)

Dè tha trì air a thoirt air falbh bho thrì a’ dèanamh aon = What does 2 subtracted from 3 make?

Cò ris a tha dhà air a thoirt air falbh bho thrì co-ionnan? = What does 2 subtracted from 3 equal?

**Multiplication/Times = Iomadachadh (le)**air iomadachadh le... = multiplied by (le does not lenite)

uiread = times, as in “trì uiread cho mòr ri sin” = three times as big as that

Tha dhà air iomadachadh le trì a’ dèanamh (co-ionnan ri) sia = 2 multiplied by 3 makes (equals/is equal to) 6.

Iomadaich dhà le trì! = Multiply 2 and 3!

Dè tha dhà air iomadachahd le trì a’ dèanamh? = What does 2 multiplied by 3 make?

Cò leis a tha dhà air iomadachadh le trì co-ionnan? = What does 2 mutiplied by 3 equal?

**Division = Roinn (le)**air a roinn le... = divided by (le does not lenite)

Tha sia air a roinn le trì a’ dèanamh (co-ionnan ri) dhà = 6 divided by 2 makes (is equal to) 2.

Roinn sia le trì! = Divide 6 by 3!

Dè tha sia air a roinn le trì a’ dèanamh? = What does 6 divided by 3 make?

Cò ris a tha sia air a roinn le trì co-ionnan? = What does 6 divided by 3 equal?
