  • axiom of extension
    • a set is determined solely by its members
  • Bilateral symmetry
    • a symmetry in which the left and right sides of the organisms can be divided into approximately.
  • Radial Symmetry
    • similar parts are arranged in a balanced way around the center of the body.
  • Fractals
    • a never-ending pattern found in nature
    • the pattern itself repeats over and over again at different scales.
  • Spirals
    • first describe by RENE DESCARTES and was later investigated by Jacob Bernoulli
    • a curved pattern that focuses on a center point and a series of circular shapes that revolve around it.
  • Tessellation is the distinct shapes are formed from several geometric unit shapes that fit together with no gaps that formed united pattern.
  • Set is simply a collection of objects that can be accessed by a variable.
  • Roster Method
    • writing all the elements inside the curly braces, especially when the set has finite number, of elements.
  • Rule Method (Set-Builder Notation)
    • describing the elements by its property that is necessary for membership, especially when a set is compose of a large finite set or an infinite set.
  • N - natural numbers
    Z - Integers
    Q - Rational numbers
    R - real numbers
    I - Imaginary numbers
    C - Complex numbers
    W - Whole numbers
  • Universal Set (U)
    • a set that contains all the elements of a given set.
  • Empty Set
    • a set with no elements
    • also known as the Null Set.
  • Subset
    • a basic relation between sets
  • Proper Subset
    • a subset which contains fewer elements of its parents set.
  • Cardinality of Sets
    • the number of elements in a given set
    • denoted by |S| where S is a set
  • Power Set
    • a set that includes the empty set and the original itself
    • usually denoted by P
  • Union of Sets
    • the set of all elements in the collection
  • Intersection of Sets
    • set of all elements that belongs to both A and B
  • Complement of a Set
    • the set of all the elements in the given universal set(U) that are not present in that specific set.
  • Set Difference
    • subtracting the elements from a set which is similar to the concept of the difference between numbers.
  • Ordered pairs
    • a pair of formed by two elements that are separated by a comma and written inside the parenthesis.
  • Cartesian Product
    • the product of any two sets, but this product is ordered
  • Relation is a subset of a Cartesian Product.
  • Function is a special kind of relation
  • Squaring Function f from R to R
    Formula: f(x) =
    - no matter what a real number input as substitute for x, the output of f is it's square.
  • Successor Function g to Z to Z
    Formula: g(n) = n+1
    -the output g is always plus than 1 to whatever the real number is being substituted in (n).
  • Constant Function h to Q to Z
    Formula: h(r)=2 for all rational number r
    -whatever rational number r might be the output would always be 2
