  1. 1. Area is the measure of the size of a surface or region, typically measured in square units.
  2. 4. An integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals.
  3. 5. A proportion is an equation that states that two ratios are equal. Proportions can be solved to find missing values in a ratio.
  4. 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).
  5. 9. The least common multiple of two or more numbers is the smallest multiple that is common to all of them.
  6. 11. An algebraic expression is a mathematical phrase that contains variables, constants, and operations (such as addition, subtraction, multiplication, and division).
  7. 13. An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.
  8. 14. The absolute value of a number is its distance from zero on the number line. It is always a non-negative value.
  9. 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.
  10. 16. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
  11. 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.

  1. 2. A ratio is a comparison of two quantities by division. It can be written as a fraction or using the colon symbol ":".
  2. 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.
  3. 6. Volume is the measure of the amount of space occupied by a three-dimensional object, typically measured in cubic units.
  4. 7. A composite number is a natural number greater than 1 that is not prime, meaning it has more than two positive divisors.
  5. 8. The y-axis is the vertical line on a coordinate plane. It represents the dependent variable in a graph.
  6. 10. A variable is a symbol (usually a letter) used to represent an unknown or changing quantity in algebraic expressions and equations.
  7. 12. The x-axis is the horizontal line on a coordinate plane. It represents the independent variable in a graph.
  8. 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).
  9. 18. The greatest common factor of two or more numbers is the largest number that divides each of them without leaving a remainder.
