Study Notes
Basic Arithmetic Operations
- Addition: Combining two or more numbers to find a total. For example, 2 + 3 = 5.
- Subtraction: Finding the difference between two numbers. For example, 5 - 2 = 3.
- Multiplication: Repeated addition of a number. For example, 2 x 3 = 6 (which is the same as 2 + 2 + 2).
- Division: Finding how many times one number goes into another. For example, 6 ÷ 2 = 3.
Number Systems
- Natural Numbers: Counting numbers (1, 2, 3,...).
- Whole Numbers: Natural numbers plus zero (0, 1, 2, 3,...).
- Integers: Whole numbers and their negative counterparts (...-3, -2, -1, 0, 1, 2, 3...).
- Rational Numbers: Numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero. Examples include 1/2, 3/4, -2/5.
- Irrational Numbers: Numbers that cannot be expressed as a fraction of two integers. Examples include π (pi) and the square root of 2.
- Real Numbers: The set of all rational and irrational numbers.
Algebra
- Variables: Symbols (like x or y) that represent unknown values.
- Expressions: Combinations of numbers and variables using arithmetic operations. Examples include 2x + 3, x² - 4y.
- Equations: Statements that show two expressions are equal. Examples include 2x + 3 = 7, x² - 4y = 0.
- Solving Equations: Finding the value of the variable that makes the equation true.
- Inequalities: Statements that compare two expressions using symbols like < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to).
Geometry
- Points: Basic locations in space.
- Lines: Straight paths extending infinitely in both directions.
- Angles: Formed by two rays sharing a common endpoint. Measured in degrees or radians.
- Shapes: Two-dimensional figures (like squares, triangles, circles) and three-dimensional objects (like cubes, spheres).
- Area: The measure of the space inside a two-dimensional shape.
- Perimeter: The total distance around the outside of a two-dimensional shape.
- Volume: The measure of the space occupied by a three-dimensional object.
Data Analysis
- Data Collection: Gathering information about a topic.
- Data Organization: Arranging data in a meaningful way (tables, charts).
- Data Interpretation: Drawing conclusions from the data.
- Mean (Average): The sum of the values divided by the total number of values
- Median: The middle value when values are sorted.
- Mode: The most frequent value.
Functions
- Functions: Relationships between variables, where one variable depends on another. For example, y = 2x.
- Domain: Set of possible input values for a function.
- Range: Set of possible output values for a function.
- Graphing Functions: Visual representation of the function's relationship using coordinates.
- Linear Functions: Straight-line graphs; represented by the equation y = mx + b.
Trigonometry
- Right-angled triangles: Relates angles and sides.
- Sine, Cosine, Tangent: Ratios of sides in a right-angled triangle with reference to an angle.
- Trigonometric Identities: Equations involving trigonometric functions that are true for all values of the angles.
Calculus
- Limits: Describing behavior of a function as input approaches a given value.
- Derivatives: Measures the instantaneous rate of change of a function.
- Integrals: Finds the accumulated change of a function over a given interval.
- Applications: Used to model and solve problems involving rates of change, area calculation, and optimization.
Number Theory
- Prime Numbers: Whole numbers greater than 1 that have only two divisors: 1 and themselves.
- Divisibility Rules: Rules to determine if a number is divisible by another.
- Greatest Common Factor (GCF): Largest number that divides two or more integers evenly.
- Least Common Multiple (LCM): Smallest positive integer that is a multiple of two or more integers.
