The term "Not Equal" refers to a mathematical relationship where two values or expressions do not have the same quantity or value. In mathematical notation, this is represented by the symbol "≠". For example, if 3 is compared to 5, we can say that 3 ≠ 5 because they are different numbers. In everyday language, "Not Equal" can also describe situations where two things are different in quality, status, or characteristics. For instance, if two people have different opinions on a topic, we can say their views are not equal. This concept helps to highlight diversity and individuality in various contexts.
