**2. Undecagon:** An “undecagon” is a polygon with eleven sides. In geometry, polygons are classified based on the number of sides they have, and the undecagon is a fascinating shape with unique properties.

**3. Undecimal:** An “undecimal” is a numeral system based on the number eleven. It uses eleven as its base and has distinct symbols to represent values. The undecimal system is not as common as the decimal system but holds significance in number theory and alternative numeral systems.

**4. Unearned Income:** In economics, “unearned income” refers to income that is received without active involvement or effort, such as interest, dividends, or rent. It is an essential concept in financial planning and analyzing income sources.

**5. Unequal:** In mathematics, “unequal” signifies that two quantities or expressions are not equal to each other. It is a fundamental concept used in equations, inequalities, and comparisons.

**6. Unequal Parts:** “Unequal parts” refer to divisions or sections that are not of the same size or magnitude. In geometry and fraction representation, understanding unequal parts is crucial for accurate measurements and comparisons.

**7. Union:** The “union” of sets is an operation that combines all the elements from two or more sets into a single set, without duplicating elements. It is represented by the symbol “∪” and plays a significant role in set theory and probability.

**8. Union of Sets:** The “union of sets” refers to the result of performing the union operation on two or more sets. It is the set containing all elements that belong to any of the sets involved.

**9. Unit:** A “unit” in mathematics is a standard quantity used to measure or express other quantities. Units provide a basis for measurement and are crucial in dimensional analysis and unit conversions.

**10. Unit Circle:** The “unit circle” is a circle with a radius of one unit, centered at the origin (0,0) in the Cartesian coordinate system. It plays a central role in trigonometry and provides a visual representation of the values of trigonometric functions.

**11. Unit Cost:** The “unit cost” is the cost of producing or obtaining a single unit of a product or service. It is a crucial aspect of business economics and production analysis.

**12. Unit Cube:** A “unit cube” is a cube with all its edges measuring one unit in length. It serves as a fundamental building block in three-dimensional geometry and volume calculations.

**13. Unit Fraction:** A “unit fraction” is a fraction where the numerator is one and the denominator is a positive integer greater than one. It represents a part of a whole divided into equal parts.

**14. Unit of Measurement:** A “unit of measurement” is a specific quantity used to express the magnitude of a physical quantity. It forms the basis for quantifying various properties in science and everyday life.

**15. Unit Price:** The “unit price” is the cost of a single unit of a product or service. It is commonly used for comparison and decision-making when buying items in bulk.

**16. Unit Rate:** The “unit rate” is a rate or ratio where the denominator is one unit. It provides a measure of how much of one quantity corresponds to one unit of another quantity.

**17. Unit Square:** A “unit square” is a square with all sides measuring one unit in length. It serves as a fundamental building block in two-dimensional geometry and area calculations.

**18. Unit Vector:** A “unit vector” is a vector with a magnitude of one unit. It is commonly used to represent directions and simplify vector calculations.

**19. Units:** “Units” refer to the standard measurements used to express quantities, such as meters, seconds, kilograms, and so on. Units play a crucial role in dimensional analysis and ensuring consistency in mathematical calculations.

**20. Univariate Data:** “Univariate data” refers to data that consists of a single variable or quantity being measured or observed. It is commonly analyzed using descriptive statistics and graphical representations.

**21. Universal Set:** The “universal set” is the set that contains all the elements or objects under consideration in a particular context. It forms the basis for set operations and set theory.

**22. Unlike Denominators:** In fractions, “unlike denominators” are denominators that are not equal to each other. When adding or subtracting fractions, converting them to have the same denominators is essential.

**23. Unlike Numerators:** In fractions, “unlike numerators” are numerators that are not equal to each other. Fractions with unlike numerators can represent different quantities.

**24. Upper Bound:** The “upper bound” of a set of numbers is the smallest number that is greater than or equal to all the numbers in the set. It is commonly used in interval notation and set theory.

**25. US Standard Units:** “US standard units” refer to the customary system of measurement used in the United States. It includes units such as inches, feet, pounds, and gallons.
