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 is called DELTA and looks like a triangle. -----> Δ <----
x or any other variable
The symbol ( y ) typically represents a variable or an unknown value in mathematics and science. It is often used to denote the dependent variable in functions, particularly in the context of Cartesian coordinates, where ( y ) represents the vertical axis. In other contexts, ( y ) may also signify a specific quantity or measurement, depending on the subject matter.
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.
x= the unknown
x
The word that describes a letter or symbol representing an unknown quantity is "variable." In mathematics and algebra, variables are often used to stand in for numbers that can change or are not yet known. Common examples of variables include letters like x, y, and z.
Variable
A variable is usually used for that - for example, a single letter that represents the unknown quantity.

In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.

In science, the symbol commonly used for an unknown quantity is "x." This convention is widely adopted across various fields, especially in mathematics and physics, where "x" represents values that need to be determined or solved for. In other contexts, such as chemistry, different symbols may be used to represent unknown substances or variables.
