Variables are a fundamental concept in mathematics, representing values that can change or vary.

In this article, we will discuss ten examples of variables in mathematics.

## Examples of Variables

These are examples of variables.

### 1: Algebraic Variables

In algebra, we use letters like x, y, and z to represent unknown or changing values.

For example, in the equation 2x + 3 = 7, “x” is a variable.

### 2: Measurement Variables

In geometry, variables represent measurements.

For example, length of a side of a triangle, the radius of a circle, or the height of a rectangle.

### 3: Time as a Variable

Time is a commonly used variable in physics and calculus. It represent moments in the past, present, or future and is often denoted by the variable “t.”

### 4: Economic Variables

In economics, variables are represent factors like price, demand, supply, and interest rates.

### 5: Statistics and Data Variables

Variables in statistics represent data values that are vary.

For example, heights of individuals in a population or the scores in an exam.

### 6: Function Variables

In calculus and function theory, variables often represent independent and dependent quantities.

For example, “x” representing inputs and “y” representing outputs in a function.

### 7: Geometry Angle Variables

In geometry, angles are often represented by variables.

For example, “Î¸” is a common variable used to represent an angle.

### 8: Probability Variables

In probability theory, variables represent outcomes or events in a experiment.

For example, result of a coin toss or the roll of a die.

### 9: Chemical Variables

In chemistry, variables represent quantities like the concentration of a substance, temperature, or pressure in chemical reactions.

### 10: Engineering Variables

In engineering, variables can represent physical properties such as velocity, force, electrical current, and temperature in various engineering applications
