A math expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
The symbol for a change in value is often represented by the Greek letter delta (Δ). In mathematics and science, Δ is used to denote a difference or change in a quantity, such as Δx for a change in position or Δt for a change in time. This notation is commonly used in various fields to indicate variations in values.

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.
