Study Notes

Basic Arithmetic Operations

  • Addition involves combining two or more numbers to find their total.
  • Subtraction involves finding the difference between two numbers.
  • Multiplication involves repeatedly adding a number to itself a specific number of times.
  • Division involves splitting a number into equal parts.

Number Systems

  • Natural numbers are positive whole numbers (1, 2, 3...).
  • Whole numbers include zero and positive whole numbers (0, 1, 2, 3...).
  • Integers include zero, positive whole numbers, and negative whole numbers (...-2, -1, 0, 1, 2...).
  • Rational numbers can be expressed as a fraction p/q where p and q are integers, and q is not zero.
  • Irrational numbers cannot be expressed as a fraction.
  • Real numbers include all rational and irrational numbers.
  • Imaginary numbers are numbers that, when squared, result in a negative number.

Algebra

  • Variables represent unknown quantities.
  • Equations state that two expressions are equal.
  • Inequalities show a relationship where one expression is greater than or less than another.
  • Linear equations represent a straight line on a graph.
  • Quadratic equations involve a variable raised to the second power.
  • Exponents represent repeated multiplication.
  • Polynomials are expressions involving variables and their exponents.

Geometry

  • Points are locations in space.
  • Lines are straight paths extending infinitely in two directions.
  • Angles are the space between two intersecting lines.
  • Triangles have three sides and three angles.
  • Polygons are two-dimensional shapes with straight sides.
  • Circles are perfectly round shapes.
  • Area measures the space inside a two-dimensional shape.
  • Perimeter measures the distance around a two-dimensional shape.
  • Volume measures the space occupied by a three-dimensional object.
  • Solid figures are three-dimensional shapes.

Measurement

  • Units of measurement are used to quantify physical quantities.
  • Standard units are used for consistency.
  • Common units include meters, centimeters, kilometers, grams, kilograms, liters, seconds, minutes, hours.

Data Analysis

  • Data collection involves gathering information.
  • Data organization involves arranging data in a structured way.
  • Data presentation involves displaying data in charts, graphs, or tables.
  • Data interpretation involves analyzing data to derive insights.
  • Measures of central tendency (e.g., mean, median, mode) summarize data.
  • Measures of variability (e.g., range, standard deviation) describe the spread of data.

Statistics

  • Statistics is the science of collecting, organizing, analyzing, interpreting, and presenting data.
  • Frequency distributions show how often different values occur.
  • Probability measures the likelihood of an event happening.
  • Samples are representative portions of a population.
  • Populations are the entire group being studied.

Functions

  • A function assigns exactly one output value to each input value.
  • Functions can be represented graphically, with tables, or algebraically with equations.
  • Linear functions produce a straight line on a graph and often follow the form y = mx + b.
  • Quadratic functions form a parabola on a graph and usually follow the form y = ax² + bx + c.
  • Exponential functions involve an exponent and can often show growth or decay.
  • Logarithmic functions are the inverse of exponential functions.

Trigonometry

  • Trigonometry deals with relationships between angles and sides of triangles.
  • Trigonometric functions (sin, cos, tan) relate angles and sides.
  • Applications of trigonometry are common in surveying, navigation, and engineering.

Calculus

  • Calculus studies change and accumulation.
  • Differential calculus deals with rates of change (derivatives).
  • Integral calculus deals with accumulation of quantities (integrals).
  • Applications include calculating areas, volumes, and velocities.
