- 1. Area is the measure of the size of a surface or region, typically measured in square units.
- 4. An integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals.
- 5. A proportion is an equation that states that two ratios are equal. Proportions can be solved to find missing values in a ratio.
- 7. Plane A coordinate plane is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Points on the plane are identified by their coordinates (ordered pairs).
- 9. The least common multiple of two or more numbers is the smallest multiple that is common to all of them.
- 11. An algebraic expression is a mathematical phrase that contains variables, constants, and operations (such as addition, subtraction, multiplication, and division).
- 13. An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.
- 14. The absolute value of a number is its distance from zero on the number line. It is always a non-negative value.
- 15. An ordered pair is a pair of numbers that specifies the coordinates of a point in a two-dimensional coordinate plane. The first number represents the x-coordinate, and the second number represents the y-coordinate.
- 16. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
- 19. A fraction represents a part of a whole. It consists of a numerator and a denominator, indicating how many parts of the whole are being considered.

- 2. A ratio is a comparison of two quantities by division. It can be written as a fraction or using the colon symbol ":".
- 3. A decimal is a way of writing numbers that are not whole numbers. It includes a decimal point to indicate the place value of each digit after the point.
- 6. Volume is the measure of the amount of space occupied by a three-dimensional object, typically measured in cubic units.
- 7. A composite number is a natural number greater than 1 that is not prime, meaning it has more than two positive divisors.
- 8. The y-axis is the vertical line on a coordinate plane. It represents the dependent variable in a graph.
- 10. A variable is a symbol (usually a letter) used to represent an unknown or changing quantity in algebraic expressions and equations.
- 12. The x-axis is the horizontal line on a coordinate plane. It represents the independent variable in a graph.
- 17. An inequality is a mathematical statement that compares the relative size of two expressions using symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), or ">=" (greater than or equal to).
- 18. The greatest common factor of two or more numbers is the largest number that divides each of them without leaving a remainder.
