    Study Notes

    Numbers and Operations

    • Number Systems:
      • Natural Numbers (N): 1, 2, 3, ...
      • Whole Numbers (W): 0, 1, 2, 3, ...
      • Integers (Z): ..., -3, -2, -1, 0, 1, 2, 3, ...
      • Rational Numbers (Q): fractions, e.g. 3/4, 22/7
      • Real Numbers (R): includes all rational and irrational numbers, e.g. π, e
    • Operations:
      • Addition: combining two or more numbers to get a total or sum
      • Subtraction: finding the difference between two numbers
      • Multiplication: repeated addition, e.g. 3 × 4 = 3 + 3 + 3 + 3
      • Division: sharing a number into equal parts or groups

    Algebra

    • Variables and Expressions:
      • Variable: a symbol representing a value that can change
      • Expression: a combination of variables, numbers, and operations
      • Equation: a statement that says two expressions are equal
    • Solving Equations:
      • Linear Equations: equations in which the highest power of the variable is 1
      • Quadratic Equations: equations in which the highest power of the variable is 2

    Geometry

    • Points, Lines, and Planes:
      • Point: a location in space, represented by a set of coordinates
      • Line: a set of points extending infinitely in two directions
      • Plane: a flat surface that extends infinitely in all directions
    • Angles and Shapes:
      • Angle: formed by two rays sharing a common endpoint
      • Types of Angles: acute, right, obtuse, straight, reflex
      • Types of Shapes: triangles, quadrilaterals, polygons, circles

    Measurement and Data

    • Units and Conversions:
      • Length: meter (m), centimeter (cm), millimeter (mm)
      • Capacity: liter (L), milliliter (mL)
      • Mass: gram (g), kilogram (kg)
    • Data Analysis:
      • Types of Data: qualitative, quantitative
      • Data Representation: tables, charts, graphs, diagrams

    Calculus

    • Limits:
      • The concept of limits is used to study how functions behave as the input values approach a certain point
    • Derivatives:
      • The derivative of a function represents the rate of change of the function with respect to the input
    • Integrals:
      • The integral of a function represents the accumulation of the function over a given interval

    Number Systems
