An unknown or changeable quantity is a variable. We use variables when we don't know what a certain amount is, and they're usually referred to as "x," or "y."
For example, if I had a problem where I needed apples, had $15, and knew that each apple was $1.50, I would use a variable to see how many apples I could buy (because right now that's an unknown number). I could solve it by writing 1.50x =15 to find my answer (which is x =10).

A changeable quantity is called a variable. Variables can take different values and are typically represented by letters in mathematical equations.
An unknown changeable quantity refers to a variable in mathematics or science whose value is not fixed and can vary or change under different conditions. It is often represented by symbols, such as ( x ) or ( y ), in equations or expressions. This concept is crucial for understanding relationships and functions, as it allows for the exploration of how different factors influence outcomes.
Phrases that describe an unknown or changeable quantity include "variable," "unknown value," "indeterminate amount," and "flexible figure." Terms like "x" or "y" in mathematical contexts represent such quantities. Additionally, phrases like "subject to change" or "estimated value" convey the idea of uncertainty or variability.
