What is the meaning of A in mathmatical terms

 

Answer:

In set theory, A refers to elements of universal set not included in Set A.

A is read as complement of Set A.

Example:

Universal Set = {a, b, c, d, e, f, g}

A = {a, c, e, g}

A = {b, d, f}   ⇒  the elements not in Set A.

Another example:

Universal Set = {a, b, c, d, e, f, g}

A =  {a, b, c, d, e, f, g}

A = ∅   ⇒  null or empty set since all elements are included in Set A.
