## NUMBER THEORY

 CONTENT: Set of numbers: whole numbers { 0, 1, 2, 3, ...}, natural numbers { 0, 1, 2, 3, ...}, integers {...-2, -1, 0, 1, 2, ...}, rational numbers (p/q:pand q are integers, q ≠ 0, Irrational numbers (numbers that cannot be expressed as terminating or recurring decimals, for example, numbers such as π (pi) and the √2), the real numbers (the union of the rational and irrational numbers); sequences of numbers that have a recognizable pattern; factors and multiples. SPECIFIC OBJECTIVES: The student should be able to: 1. Distinguish between sets of numbers (for example, integers and rational numbers); 2. Order a set of rational numbers; 3. Identify a given set of numbers as a subset of another set; 4. Describe positive integers as being prime or composite; 5. List the set of factors or a set of multiples of a given postive integer or a set of positive integers; 6. Compute the H.C.F or L.C.M. of two or more postive integers; 7. State the place value of a digit in a numeral in any base; 8. Use certain number properties and concepts (for example, identity, inverse, closure, associativity, commutativity, distributivity) in: (a) solving equations (b) simplifying computational tasks 9. Use investigations to make inferences and generalizations, utilizing the concepts listed above.
