    Numbers and Operations

    • Types of Numbers:
      • Natural Numbers (1, 2, 3, ...)
      • Whole Numbers (0, 1, 2, 3, ...)
      • Integers (...,-3, -2, -1, 0, 1, 2, 3, ...)
      • Rational Numbers (fractions, decimals)
      • Irrational Numbers (non-repeating, non-terminating decimals)
    • Number Operations:
      • Addition (+)
      • Subtraction (-)
      • Multiplication (×)
      • Division (÷)
      • Exponents (powers)
      • Roots (square, cube, etc.)

    Algebra

    • Variables and Expressions:
      • Variables (letters or symbols representing unknown values)
      • Expressions (combinations of variables, numbers, and operations)
      • Simplifying expressions (combining like terms)
    • Equations and Inequalities:
      • Linear Equations (e.g. 2x + 3 = 5)
      • Quadratic Equations (e.g. x^2 + 4x + 4 = 0)
      • Inequalities (e.g. 2x - 3 > 5)

    Geometry

    • Points, Lines, and Planes:
      • Points (locations in space)
      • Lines (sets of points extending infinitely)
      • Planes (flat surfaces)
    • Angles and Measurements:
      • Angle types (acute, obtuse, right, straight)
      • Degree measurements (0° - 360°)
      • Calculating perimeter and area of shapes

    Statistics and Probability

    • Data Analysis:
      • Types of data (qualitative, quantitative)
      • Data visualization (charts, graphs, tables)
      • Measures of central tendency (mean, median, mode)
    • Probability:
      • Basic concepts (events, sample spaces, probability rules)
      • Calculating probability (theoretical, experimental)
      • Conditional probability and independence

    Calculus

    • Limits:
      • Concept of limits
      • Evaluating limits (direct substitution, factoring)
    • Derivatives:
      • Definition of derivatives
      • Rules of differentiation (power rule, product rule, etc.)
      • Applications of derivatives (optimization, motion)
    • Integrals:
      • Definition of integrals
      • Basic integration rules (substitution, integration by parts)
      • Applications of integrals (area, volume, work)

    Numbers and Operations

    • There are five types of numbers: Natural Numbers, Whole Numbers, Integers, Rational Numbers, and Irrational Numbers.

    • Natural Numbers are positive integers starting from 1.

    • Whole Numbers are non-negative integers including 0.

    • Integers include all whole numbers and their negative counterparts.

    • Rational Numbers are expressed as fractions or decimals.

    • Irrational Numbers are non-repeating, non-terminating decimals.

    • There are six basic number operations: Addition, Subtraction, Multiplication, Division, Exponents, and Roots.

    • Addition and subtraction are inverse operations, as are multiplication and division.

    • Exponents represent repeated multiplication, and roots represent the opposite operation.

    Algebra

    • Variables are letters or symbols representing unknown values.
    • Expressions are combinations of variables, numbers, and operations.
    • Simplifying expressions involves combining like terms.
    • Equations are statements that express the equality of two expressions.
    • Inequalities are statements that compare two expressions using greater than, less than, or equal to.

    Geometry

    • A point is a location in space, represented by a set of coordinates.
    • A line is a set of points extending infinitely in two directions.
    • A plane is a flat surface that extends infinitely.
    • Angles are formed by two rays sharing a common endpoint.
    • Angles can be acute, obtuse, right, or straight.
    • Degrees are used to measure angles, ranging from 0° to 360°.

    Statistics and Probability

    • Data can be qualitative or quantitative.
    • Data visualization involves using charts, graphs, and tables to display data.
    • Measures of central tendency include the mean, median, and mode.
    • Probability is a measure of the likelihood of an event occurring.
    • Probability rules include the complement rule and the multiplication rule.
    • Conditional probability and independence are used to calculate the probability of multiple events.

    Calculus

    • Limits are used to study how functions behave as the input approaches a certain value.
    • The concept of limits is essential for understanding calculus.
    • Evaluating limits involves using direct substitution, factoring, or other methods.
    • Derivatives measure the rate of change of a function.
    • The definition of derivatives involves the limit of the difference quotient.
    • Rules of differentiation include the power rule, product rule, and quotient rule.
    • Applications of derivatives include optimization and motion problems.
    • Integrals are used to calculate the area under curves or the accumulation of a quantity.
    • The definition of integrals involves the limit of the sum of the areas of rectangles.
    • Basic integration rules include substitution, integration by parts, and integration by partial fractions.
    • Applications of integrals include finding area, volume, and work.
