👉 Invariance, also known as invariance, is a concept in mathematics that refers to properties or features that remain unchanged under certain transformations. In other words, it describes how one quantity remains constant when another quantity is changed. For example, if we have two variables x and y, the property of x remaining constant when y changes can be represented by the statement "x = y". This means that no matter what value we assign to x, the value of y will always remain the same
