For example if a 1 3 5 7 and b 1 2 4 6 8 then a b 1 2 3 4 5 6 7 8.

Math union of two sets. The union of two sets is the set of elements which are in either set. Given two sets a and b the union is the set that contains elements or objects that belong to either a or to b or to both. The union of two sets a and b is the set of elements which are in a in b or in both a and b. We write a b basically we find a b by putting all the elements of a and b together.

Enter the value of set a and set b as shown and click calculate to obtain the union of two sets. Union of two sets. So the union of sets a and b is the set of elements in a or b or both. We next illustrate with examples.

Let a 1 2 3 and let b 3 4 5. The union is notated a b. Now the union of a and b written a b 1 2 3 4 5. A b x x a or x b.

The formal definition of union is shown below. More formally x a b if x a or x b or both the intersection of two sets contains only the elements that are in both sets. A union b is represented as aub. The set made by combining the elements of two sets.

The symbol is a special u like this. The following table gives some properties of union of sets. For example if a 1 3 5 7 and b 1 2 4 6 7 then a b 1 2 3 4 5 6 7. It is denoted by a b and is read a union b.

Scroll down the page for more examples. The union of two sets contains all the elements contained in either set or both sets. Commutative associative identity and distributive. There is no need to list the 3 twice.

A more elaborate example involving two infinite sets is. The union of two sets a and b is the set of elements which are in a or in b or in both. A b given two sets a and b define their intersection to be the set a b x u x a x b loosely speaking a b contains elements common to both a and b. The union of two sets a and b is the set of elements which are in a or in b or in both.
