• Infinite set: A set with unlimited elements (e.g., natural numbers $\{1, 2, 3, \dots\}$).
• Empty set: A set with no elements ($\emptyset$ ).
• Subset: A set where every element is also in another set.
• Universal set: The set containing all possible elements in a particular context.

16. What Are the Types of Transformations in Math?

• Translation: Moving an object without rotating or flipping it.
• Rotation: Rotating around a point.
• Reflection: Flipping over a line.
• Dilation: Expanding or shrinking proportionally.

17. What Are Variables and Constants in Math?

• Variable: A symbol (e.g., $x$ ) that represents an unknown value in an equation.
• Constant: A fixed value (e.g., $5$ , $\pi$ ) that does not change.
