In algebraic language the term "null set" means the same thing as "empty set".

In algebra, a *set* is a group of numbers and the members of the set are called *elements*.

If A = the set of all odd numbers from 3 to 10, then

A ={3,5,7,9}

Sometimes sets have a non-ending number of elements, an exact number of elements, or no elements.

The set with no elements is the null set and it is shown by { } or a zero with a slash through it. It is an empty set. Here is an example:

If A = {3,5} and B = {4,6,8,10} then A nn B = { } since sets A and B share no common elements.

Remember not to confuse the null set, { }, with {0} because this set has one element and is not empty.

null set is a set wit no elements and is sown by {}. Bit do not be confused wuth {} and {0} for the latter part has an element and therefore is not a null set
