    LEARNING OUTCOMES

    • Define and identify the elements of logical expressions (atomic propositions, logical operations - negation, conjunction, disjunction, implication, equivalence, compound propositions).
    • Demonstrate knowledge of logical variables, logical operators and operator precedence by formalizing natural language statements as syntactically and semantically correct logical expressions and by evaluating logical expressions.
    • Produce truth tables for compound expressions.
    • Define tautology, contradiction, contingency, logical equivalence, logical implication.
    • Use truth tables to verify/refute the aforementioned.
    • Use the Laws of Logic to verify/refute the aforementioned and simplify expressions.
    • Use deductive proofs (Rules of Inference) to test the validity of arguments.
    • Define sets, including the empty set, and the universal set with specific reference of the standard universal sets.
    • Describe sets by enumeration and comprehension.
    • Define and evaluate set cardinality.
    • Define and use set equality and set inclusion.
    • Define and obtain power sets and evaluate their cardinality.
    • Define and use set operations.
    • Know and apply the Principle of Inclusion and Exclusion.
    • Recall and use the laws of set theory to simplify set algebraic expressions and to prove set identities.
    • Explain what sequences are.
    • Evaluate the general term of, and enumerate a sequence.
    • Recognize and describe the difference between recursive and non-recursive definitions.
    • Define sequences by means of recursive definitions and enumerate sequences defined recursively.
    • Recall and use the division theorem.
    • Define and establish divisibility.
    • Recognize and use the ?mod? function.
    • Define modular congruence and perform congruence arithmetic.
    • Define prime and composite numbers, demonstrate use of the Sieve of Eratosthenes, and find prime factorisations using trial division. Knowledge and use of the smallest prime factor theorem is essential.
    • Recall the Fundamental Theorem of Arithmetic.
    • Define the greatest common denominator, determine by factorisation and by the Euclidean algorithm.
    • Define the term coprime (relatively prime) and test for coprimality.
    • Recall the linear combination theorem and express the gcd as a linear combination.
    • Recall the theorem regarding the divisibility of congruences, define and obtain the inverse modulo m and define and solve linear congruences.
    • Demonstrate the application of number theory to: hash functions, pseudorandom number generators, and simple ISBN check digit evaluation and the correction of single digit errors.
    • Discuss and analyze cryptosystems with reference to: encryption and decryption, keys and keyspaces, shift ciphers, and affine ciphers.
    • Define and recognize matrices and vectors and demonstrate knowledge of the notation used to refer to matrices, vectors, and their elements.
    • Demonstrate knowledge of matrix terminology i.e. element, row vector, column vector, square matrix, null matrix, identity matrix, unit matrix, diagonal element, principal diagonal, diagonal matrix, symmetric matrix, triangular matrix.
    • Evaluate matrix algebra expressions involving equality, transposition, addition, subtraction, scalar multiplication, vector product, matrix product, matrix power, including the join, meet, product and powers of Boolean matrices.
    • Define, explain and recognize essential graph theoretical terminology.
    • Know and apply selected graph theoretical theorems.
    • Represent graphs using adjacency matrices and know and apply essential theorems relating to their use to answer questions regarding connectivity of graphs.
    • Use Dijkstra's algorithm to solve shortest path problems.
    • Define and identify trees, subtrees, and rooted trees and with regard to the vertices of rooted trees: root, parent, child, sibling, ancestor, descendant, internal vertex, leaf, level, height, balanced tree, m-ary tree, full m-ary tree, and binary tree.
    • Recall and use the theorems relating to trees.
    • Perform the three tree traversal algorithms: inorder, preorder, postorder.
    • Demonstrate the use of binary trees for binary search trees, prefix codes and expression trees.
    • Define spanning trees and minimum spanning trees and produce minimum spanning trees by means of Prim?s algorithm.
