Study Notes
Arithmetic
- Arithmetic is the branch of mathematics dealing with basic number operations: addition, subtraction, multiplication, and division.
- It underpins more complex mathematical concepts.
- Fundamental arithmetic operations:
- Addition: Combining quantities.
- Subtraction: Finding the difference between quantities.
- Multiplication: Repeated addition.
- Division: Finding how many times one quantity is in another.
- Arithmetic properties:
- Commutative property: Order doesn't change result (a + b = b + a, a × b = b × a).
- Associative property: Grouping doesn't change result ((a + b) + c = a + (b + c), (a × b) × c = a × (b × c)).
- Distributive property: Multiplication distributes over addition (a × (b + c) = (a × b) + (a × c)).
- Order of operations (PEMDAS/BODMAS):
- Parentheses (Brackets)
- Exponents (Orders)
- Multiplication and Division (left to right)
- Addition and Subtraction (left to right)
Algebra
- Algebra uses symbols (variables) to represent numbers and relationships.
- It expands on arithmetic by introducing unknowns to solve for.
- Key algebraic concepts:
- Variables: Symbols for unknown or changing values.
- Equations: Statements of equality between expressions.
- Inequalities: Relationships between expressions using symbols like <, >, ≤, ≥.
- Formulas: Equations representing variable relationships.
- Solving equations: Finding variable values that make the equation true.
- Techniques involve isolating the variable through inverse operations.
- Solving inequalities uses similar methods, maintaining the inequality sign.
Geometry
- Geometry studies shapes, sizes, positions, and spatial properties.
- Common shapes and their properties:
- Points, lines, planes
- Angles
- Triangles, quadrilaterals, polygons
- Circles, spheres, cylinders
- Formulas calculate area, perimeter, and volume.
- Geometry types include Euclidean, non-Euclidean, and coordinate geometry.
Calculus
- Calculus analyzes rates of change and accumulation.
- Differentiation: Finding instantaneous rate of change.
- Integration: Finding accumulated change.
- Applications include curve slopes, areas, volumes, optimization, and differential equation solving.
Number Theory
- Number theory examines number properties, prime numbers, divisibility, and related areas.
- Prime numbers: Greater than 1, divisible only by 1 and themselves.
- Divisibility rules: Determine if a number is divisible by another.
- Congruences: A form of equality expressing remainders when dividing.
- Connections to cryptography.
Statistics
- Statistics involves collecting, organizing, analyzing, interpreting, and presenting data.
- Descriptive statistics: Summarizing and describing data sets.
- Inferential statistics: Drawing conclusions about a population from a sample.
- Measures of central tendency (mean, median, mode) describe data.
