Study Notes
Fundamental Operations
- Addition: Combining two or more numbers to find their sum. The result is called the sum.
- Subtraction: Finding the difference between two numbers. The result is called the difference.
- Multiplication: Repeated addition of the same number. The result is called the product.
- Division: Breaking a number into equal parts. The result is called the quotient.
Number Systems
- Natural Numbers (ℕ): Positive integers (1, 2, 3,...).
- Whole Numbers (ℤ⁺): Non-negative integers (0, 1, 2, 3,...).
- Integers (ℤ): Whole numbers (positive, negative, and zero).
- Rational Numbers (ℚ): Numbers that can be expressed as a fraction p/q, where p and q are integers, and q ≠ 0.
- Irrational Numbers: Numbers that cannot be expressed as a fraction of two integers.
- Real Numbers (ℝ): The set of all rational and irrational numbers.
- Complex Numbers (ℂ): Numbers that can be expressed in the form a + bi, where a and b are real numbers, and i is the imaginary unit (i² = -1).
Basic Algebra
- Variables: Symbols used to represent unknown values (e.g., x, y, z).
- Equations: Statements that show that two mathematical expressions are equal (e.g., x + 2 = 5).
- Inequalities: Statements that show that two mathematical expressions are not equal (e.g., x < 5).
- Polynomials: Expressions consisting of variables and coefficients combined using addition, subtraction, and multiplication (e.g., 2x² + 3x - 1).
- Factoring: Breaking down an expression into simpler expressions that multiply together to create the original expression.
- Solving Equations: Finding the value of the variable that makes the equation true.
- Order of Operations (PEMDAS/BODMAS): The specific sequence for evaluating expressions containing multiple operations (Parentheses/Brackets, Exponents/Orders, Multiplication and Division from left to right, Addition and Subtraction from left to right).
Geometry
- Points: Basic building blocks of geometry, often represented by a dot.
- Lines: Straight paths extending infinitely in both directions.
- Angles: Formed by two lines or rays that share a common endpoint.
- Triangles: Polygons with three sides and three angles. Types include equilateral, isosceles, and scalene.
- Quadrilaterals: Polygons with four sides and four angles. Types include parallelograms, rectangles, squares, rhombuses, and trapezoids.
- Circles: A set of points equidistant from a central point.
- Perimeter: The total distance around a two-dimensional shape.
- Area: The amount of space enclosed within a two-dimensional shape.
- Volume: The amount of space occupied by a three-dimensional object.
Statistics and Probability
- Data: Sets of observations or measurements.
- Mean: The average of a set of data.
- Median: The middle value in a sorted set of data.
- Mode: The most frequent value in a set of data.
- Standard Deviation: A measure of the spread of data around the mean.
- Probability: The likelihood of an event occurring.
- Sample Space: Set of all possible outcomes of an event.
Trigonometry
- Trigonometric Functions: Functions relating the angles and sides of a right triangle (sine, cosine, tangent, etc.)
- Right Triangles: Triangles with a 90-degree angle.
- Angle Measurement: Using degrees or radians to quantify angles.
- Applications: Solving for unknown sides or angles in right triangles; modeling periodic phenomena.
