I'm trying to understand what the letter 'U' represents in mathematical inequalities. I've seen it used in some contexts, but I'm not sure of its exact meaning or how it affects the interpretation of the inequality.

Inequality notation utilizing intervals is a precise way to express mathematical conditions involving "or" relationships. When dealing with such inequalities, numbers are placed within distinct groupings to signify that only one of the conditions needs to be satisfied.

The grouping symbols enclose the individual sets of numbers, allowing for clarity and precision in mathematical expressions. This approach ensures that the reader understands that the inequality applies to either one set of numbers or the other, but not necessarily both simultaneously.

To indicate the "or" relationship between the two sets of numbers, the symbol "U" is employed. This symbol, representing the union of two sets, is used to connect the two intervals, signifying that the inequality holds true for all values within either of the specified ranges.

For instance, consider the inequality x < 5 or x > 10. This condition can be expressed using interval notation as ( − ∞ , 5 ) U ( 10 , ∞ ). This notation clearly conveys that the variable x can take on any value less than 5 or greater than 10, satisfying the "or" condition.
