Study Notes
Basic Arithmetic Operations
- Addition: Combining two or more numbers to find a total.
- Subtraction: Finding the difference between two numbers.
- Multiplication: Repeated addition of a number.
- Division: Separating a number into equal parts.
Number Systems
- Natural numbers (N): Counting numbers (1, 2, 3,...).
- Whole numbers (W): Natural numbers plus zero (0, 1, 2, 3,...).
- Integers (Z): Whole numbers and their opposites (..., -3, -2, -1, 0, 1, 2, 3,...).
- 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. Examples include π and √2.
- Real numbers (R): The set of all rational and irrational numbers.
- Complex numbers: Numbers that include real and imaginary parts (a + bi), where 'a' and 'b' are real numbers and 'i' is the imaginary unit (√-1).
Algebra
- Variables: Symbols (like x, y, z) that represent unknown values.
- Expressions: Combinations of numbers, variables, and operations.
- Equations: Statements that show two expressions are equal.
- Inequalities: Statements that show one expression is greater than or less than another.
- Solving equations: Finding the values of variables that make an equation true.
- Polynomials: Expressions with variables and coefficients, involving sums of terms with positive integer powers of variables.
Geometry
- Points: Locations in space.
- Lines: Straight paths extending infinitely in both directions.
- Angles: Formed by two rays meeting at a common endpoint.
- Triangles: Three-sided polygons.
- Quadrilaterals: Four-sided polygons.
- Circles: Sets of points equidistant from a center point.
- Area: The measure of a two-dimensional region.
- Volume: The measure of a three-dimensional space.
Measurement
- Units of length: Millimeters, centimeters, meters, kilometers.
- Units of area: Square meters, square centimeters.
- Units of volume: Cubic meters, cubic centimeters.
- Units of mass: Grams, kilograms.
- Units of time: Seconds, minutes, hours, days.
Data Analysis and Probability
- Data: Collections of information.
- Statistics: Methods for collecting, organizing, analyzing, and interpreting data.
- Measures of central tendency: Mean, median, mode.
- Measures of dispersion: Range, standard deviation.
- Probability: The likelihood of an event occurring.
Sets
- Sets: Collections of elements.
- Intersection of sets: Elements common to both sets.
- Union of sets: All elements in either (or both) sets.
- Subsets: One set completely contained within another.
Functions
- Functions: Relationships where each input has exactly one output.
- Domain: Set of all possible input values.
- Range: Set of all possible output values.
- Linear functions: Functions that form a straight line on a graph.
- Quadratic functions: Functions involving a variable squared.
Trigonometry
- Right-angled triangles: Triangles with a 90-degree angle.
- Trigonometric ratios: Sine, cosine, tangent, relating the sides and angles of a right-angled triangle.
- Applications of trigonometry: Solving for unknown sides and angles in triangles.
Calculus (Elementary Level)
- Limits: Approaching a value as something gets closer to a specific number.
- Derivatives: Rate of change of a function.
- Integrals: Accumulation of a function.
