An elipsis or * * * is used to present a change of scene.
In mathematics, a symbol that represents an unknown quantity is typically denoted by a variable, such as "x" or "y". These variables are used to represent values that are not yet known or are subject to change. They are commonly used in algebraic equations to solve for the unknown quantity based on given information or conditions.
The symbol used to represent change in an equation is Δ (delta). It indicates the difference or change between two values.
