Study Notes

Numbers and Operations

  • Number Systems:
    • 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 decimals)
    • Real numbers (all rational and irrational numbers)
  • Operations:
    • Addition (+)
    • Subtraction (-)
    • Multiplication (×)
    • Division (÷)
    • Exponentiation (^)
    • Root extraction (√)

Algebra

  • Variables and Expressions:
    • Variables (letters or symbols representing unknowns)
    • Algebraic expressions (combinations of variables and constants using operations)
    • Simplifying expressions (combining like terms)
  • Equations and Inequalities:
    • Linear equations (degree 1, e.g., 2x + 3 = 5)
    • Quadratic equations (degree 2, e.g., x^2 + 4x + 4 = 0)
    • Inequalities (statements with <, >, ≤, or ≥)

Geometry

  • Points, Lines, and Planes:
    • Points (locations in space)
    • Lines (sets of points extending infinitely in two directions)
    • Planes (flat surfaces extending infinitely in all directions)
  • Angles and Measurements:
    • Angle types (acute, obtuse, right, straight)
    • Angle measurements (degrees, radians)
    • Perimeter and area of various shapes (triangles, quadrilaterals, polygons, circles)

Data Analysis and Statistics

  • Data Types:
    • Qualitative (categorical, non-numerical)
    • Quantitative (numerical)
  • Data Visualization:
    • Charts (bar, pie, histogram)
    • Graphs (line, scatter)
  • Measures of Central Tendency:
    • Mean
    • Median
    • Mode
  • Measures of Variability:
    • Range
    • Interquartile range (IQR)
    • Standard deviation

Numbers and Operations

  • Natural numbers start from 1 and go upwards (1, 2, 3,...)
  • Whole numbers include natural numbers and 0 (0, 1, 2, 3,...)
  • Integers include all whole numbers and their negative counterparts (...,-3, -2, -1, 0, 1, 2, 3,...)
  • Rational numbers are fractions or decimals that can be expressed as a finite decimal or a ratio of integers
  • Irrational numbers are non-repeating decimals
  • Real numbers include all rational and irrational numbers

Algebra

  • Variables are letters or symbols used to represent unknown values
  • Algebraic expressions combine variables and constants using operations
  • Simplifying expressions involves combining like terms

Equations and Inequalities

  • Linear equations have a degree of 1 (e.g., 2x + 3 = 5)
  • Quadratic equations have a degree of 2 (e.g., x^2 + 4x + 4 = 0)
  • Inequalities are statements with <, ≤, >, or ≥

Geometry

  • Points are locations in space
  • Lines are sets of points extending infinitely in two directions
  • Planes are flat surfaces extending infinitely in all directions

Angles and Measurements

  • Angle types include acute, obtuse, right, and straight
  • Angle measurements can be in degrees or radians
  • Perimeter and area can be calculated for various shapes (triangles, quadrilaterals, polygons, circles)

Data Analysis and Statistics

  • Qualitative data is categorical and non-numerical
  • Quantitative data is numerical

Data Visualization

  • Charts include bar, pie, and histogram charts
  • Graphs include line and scatter graphs

Measures of Central Tendency

  • Mean is a measure of central tendency
  • Median is the middle value in a dataset
  • Mode is the most frequently occurring value in a dataset

Measures of Variability

  • Range is the difference between the highest and lowest values
  • Interquartile range (IQR) is the difference between the 3rd and 1st quartiles
  • Standard deviation is a measure of spread from the mean
