Study Notes
Course I: Numbers Sets
- Natural numbers (N): A set of counting numbers, {1, 2, 3,...}
- Cardinal numbers (counting numbers): Used to count items. Examples provided in tables include translating numbers into written words (e.g., one, two, eleven, etc.).
Ordinal Numbers (Place Numbers)
- Ordinal numbers: Specify position in a sequence. Examples include first, second, third, etc. Examples are given in tables translating numbers into written words (e.g., 1st, 2nd, 11th, etc.).
Whole Numbers
- Set of whole numbers (ℕ∪{0}): Includes zero and all natural numbers {0, 1, 2,...}
- Odd numbers: Numbers not divisible by 2 (e.g., 1, 3, 5, ...)
- Even numbers: Numbers divisible by 2 (e.g., 0, 2, 4, ...)
Integers
- Set of integers (Z): Includes zero, positive and negative whole numbers {..., -3, -2, -1, 0, 1, 2, 3,...}
Rational Numbers
- Set of rational numbers (Q): Numbers that can be expressed as a fraction (a/b), where 'a' and 'b' are integers and 'b' is not zero. Examples included.
Real Numbers
- Set of real numbers (R): Includes all rational and irrational numbers. Examples include √2, π, and 2.548.
Complex Numbers
- Set of complex numbers (C): Numbers that can be expressed in the form x + yi, where 'x' and 'y' are real numbers, and 'i' is the imaginary unit (i² = -1). Examples shown.
Course II: Operations & Binary Relations
Operations on Numbers
-
Operations list: Includes addition (+), subtraction (-), multiplication (× or *), and division (÷ or /) operations as well as their spelling variations.
-
Examples: The examples include the basic mathematical operations. Examples include 2 + 3 = 5, 5 – 4 = 1, 2 x 5 = 10, 10 ÷ 2 = 5.
Comparison
-
Comparison symbols: Symbols used to compare values. Include < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), = (equal to).
-
There's also an approximately equal symbol and other symbols are used in expressions.
Module 1: 1.2 Fractions, Powers, Roots
-
Fractions: Fractions consist of a numerator and denominator. Examples include simple fractions (2/3) and mixed fractions (1 1/2). Various arithmetic operations can be performed on them
-
Powers: Raising a number to an exponent (e.g., x²). Exponents condense multiplications into a shorter mathematical form.
-
Roots: Indicate the number that yields a given result when raised to a power. (e.g., √9 is the square root of 9).
Module 1: 1.3 Geometry
-
Geometry: A branch of mathematics dealing with shapes, lines, angles, surfaces, and solids.
-
Angles: Geometric figures formed by two rays sharing a common endpoint. Types of angles include acute, obtuse, right, reflex, and straight angles.
-
Triangles: Three-sided geometric figures. The types of triangles are classified by their side lengths (scalene, isosceles, equilateral).
Module 1: 2-D and 3-D Shapes
-
2-D Shapes: Flat shapes like squares, triangles, rectangles, circles, etc.
-
3-D Shapes (solids): 3-dimensional shapes like cubes, cylinders, spheres, pyramids, etc.
