  1. 3. Represented as a numerical value, which defines a part of a whole. It can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
  2. 7. It helps divide something or give a share or part of something. It is a property of multiplication used in addition and subtraction.
  3. 8. Numbers that can be positive, negative or zero. They can’t be a fractional number.
  4. 10. A form of writing a given mathematical concept like an equation, number, or an expression in a form that follows certain rules. Representing very large or very small numbers concisely.
  5. 11. Flipping an object about a line without changing its size or shape. It may occur in a point, a line, or a plane.
  6. 12. A term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.
  7. 13. A set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries.
  8. 14. A general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the pre-Image and the final shape.
  9. 16. The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept. A way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable.
  10. 18. It is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. It can be made by dividing an integer with an integer.
  11. 19. Numbers that are a set of whole numbers and can be used for counting and ordering. It does not include 0 and fractional numbers.
  12. 20. The sum of the squared sides of a right triangle equals the length of the hypotenuse squared. If you know the length of any 2 sides of a right triangle you can use it to find the length of the third side.

  1. 1. A set of numbers that include natural numbers and 0. Negative and fractional numbers are not included.
  2. 2. It is a real number that cannot be represented as a simple fraction. These cannot be expressed in the form of a ratio, such as p/q, where p and q are integers.
  3. 4. A strategy for solving systems of equations that include solving for one variable and using that solution to find the other variable. it involves finding the value of x-variable in terms of y-variable and then substituting or replacing the value of x-variable in the second equation
  4. 5. Algebraic expression that gives the distances between pairs of points in terms of their coordinates. These points can be in any dimension.
  5. 6. A type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. It stays the same shape and size, but the figures may be turned in different directions.
  6. 9. The measure of the steepness and the direction of the line. Finding the slope of lines in a coordinate plane can help in predicting whether the lines are parallel, perpendicular, or none without actually using a compass.
  7. 15. It uses two or more numbers to compare. It indicates how many times one number contains another.
  8. 17. A symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power. Also known as the power of a number.
