Matamaitic » Loighic & Tacartheoiric Is ionann aontas (nó suim) na dtacar A agus B agus tacar na mball sin a bhaineann le ceann ar a laghad den dá thacar. Is mar a chéile é do líon níos mó de thacair, fiú do líon éigríochta.
Mathematics » Logic & Set Theory The union (or sum) of the sets A and B is the set of those elements which belong to at least one of the sets. Similarly, for a greater (even infinite) number of sets.

An t-ainm a thugtar ar mhír de thacar. (Ríomhaireacht) 1. Aidhm, aonán nó coincheap a bhfuil na hairíonna aige/aici atá sainiúil do thacar. 2. Luach paraiméadair i liosta luachanna paraiméadar. 3. An t-aonad is lú sonraí i dtábla nó in eagar. 4. (Loighic) An gaol idir ball agus tacar a léirítear sa ráiteas is ball den tacar X é x agus a scríobhtar mar x ∈ X. Glactar leis gur gaol neamhshainithe é seo.
The name given to an item in a set. (Computing) 1. An object, entity, or concept having the properties that define a set. 2. A parameter value in a list of parameter values. 3. The smallest unit of data in a table or array. . (Logic) The relationship between an element and a set indicated by the statement x is an element of the set X and written as x ∈ X. This is taken as an undefined relationship.

Matamaitic » Loighic & Tacartheoiric Chun gur ball de thacar fírinne abairte oscailte é ball x atá ina bhall den uilethacar is gá agus is leor gur tairiscint fhíor atá mar thoradh ar é a chur in ionad na hathróige.
Mathematics » Logic & Set Theory An element x which is a member of the universal set, is an element of the truth set of an open sentence if and only if its substitution results in a true proposition.

Matamaitic » Loighic & Tacartheoiric Is ionann an difríocht (nó an comhlánú coibhneasta) idir na tacair A agus B agus tacar na mball sin de A nach bhfuil i B.
Mathematics » Logic & Set Theory The difference (or relative complement) of the sets A and B is the set of those elements of A which do not belong to B.

Matamaitic » Loighic & Tacartheoiric Is ionann idirmhír na dtacar A agus B agus tacar na mball a bhaineann go comhuaineach le A agus le B. [Is mar a chéile é do líon níos mó tacar (fiú do líon éigríochta).]
Mathematics » Logic & Set Theory The intersection (or product) of the sets A and B is the set of elements belonging simultaneously to both A and B. [Similarly, for a greater (even infinite) number of sets.]

Matamaitic » Loighic & Tacartheoiric Deirtear go bhfuil dhá thacar comhionann más gá agus más leor gach ball de gach aon tacar a bheith ina bhall den tacar eile. Nuair atá A agus B comhionann, scríobhtar A = B.
Mathematics » Logic & Set Theory Two sets are said to be identical if and only if every element of each is an element of the other. When A and B are identical, we write A = B.
#
Matamaitic » Loighic & Tacartheoiric Bíonn dhá thacar (nó breis) scartha mura mbíonn aon bhall coiteann iontu. Is comhionann a n-idirmhír agus an tacar neamhnitheach nó folamh.
Mathematics » Logic & Set Theory Two (or more) sets are disjoint if they have no common element. Their intersection is identical to the null or empty set.
