The symbol 'U' signifies the concept of "union," which embodies the merging or joining of two distinct entities. In mathematical contexts, this union operation finds application when dealing with solution sets.

When encountered between two solution sets, the notation 'AU' indicates the formation of a larger, comprehensive solution set. This new set encompasses all elements present in both of its constituent sets, forming a unified whole.

To illustrate, consider the expression (5,7)U(7,10). Here, two intervals are defined: one from 5 to 7, exclusive of 7, and another from 7 to 10, inclusive of 7. The union operation is applied to these intervals.

The result of the union is a single, continuous interval that spans from 5 to 10, with all numbers in this range being included. Notably, despite 7 being excluded in the first interval, it is incorporated into the larger solution set as a result of the union.

The use of parentheses in the notation serves a crucial purpose. They delineate the boundaries of each individual set, clarifying which elements are and are not included. In this example, the parentheses emphasize that 7 is not part of the first interval but becomes a member of the larger union.
