Basic Arithmetic and Number Systems

Basic Arithmetic Operations

• Addition: Combining two or more numbers to find their total.
• Subtraction: Finding the difference between two numbers.
• Multiplication: Repeated addition of the same number.
• Division: Separating a number into equal parts.

Number Systems

• Natural numbers (counting numbers): 1, 2, 3, ...
• Whole numbers: Natural numbers and 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.
• Irrational numbers: Numbers that cannot be expressed as a fraction of two integers.
• Real numbers: The set of all rational and irrational numbers.
• Complex numbers: Numbers that include both real and imaginary components, expressed in the form a + bi, where 'a' and 'b' are real numbers and 'i' is the imaginary unit (√−1).

Algebra

• Variables: Symbols used to represent unknown quantities.
• Expressions: Combinations of variables, numbers, and operators.
• Equations: Statements that two expressions are equal.
• Inequalities: Statements that compare two expressions using symbols like <, >, ≤, ≥.
• Solving equations: Finding the value of the unknown variable that makes the equation true.
• Solving inequalities: Finding the range of values of the unknown variable that make the inequality true.
• Functions: Relationships between variables, where each input has a unique output.
• Linear equations: Equations that represent a straight line on a graph.
• Quadratic equations: Equations that can be written in the form ax² + bx + c = 0, where 'a', 'b', and 'c' are constants and 'x' is the variable.

Geometry

• Points: Basic building blocks of geometry.
• Lines: One-dimensional figures that extend infinitely in both directions.
• Planes: Two-dimensional surfaces that extend infinitely in all directions.
• Angles: Formed by two rays sharing a common endpoint.
• Polygons: Closed figures formed by line segments.
• Triangles: Polygons with three sides.
• Quadrilaterals: Polygons with four sides.
• Circles: Set of all points equidistant from a central point.
• Perimeter: The total distance around a two-dimensional shape.
• Area: The amount of space enclosed by a two-dimensional shape.
• Volume: The amount of space occupied by a three-dimensional object.
• Solid shapes: Three-dimensional figures like cubes, spheres, cones, and cylinders.

Calculus

• Limits: The value a function approaches as an input approaches a certain value.
• Derivatives: Rate of change of a function.
• Integrals: Accumulation of a function.
• Applications: Optimization, motion, and modeling.

Statistics

• Data collection: Gathering information.
• Data organization: Arranging information in a meaningful way.
• Data analysis: Interpreting data to draw conclusions.
• Measures of central tendency (mean, median, mode): Representing the central point of a dataset.
• Measures of dispersion (range, standard deviation): Describing the spread of data.
• Probability: The likelihood of an event occurring.

Discrete Mathematics

• Sets: Collections of objects.
• Relations: Connections between objects.
• Functions: Relationships between inputs and outputs.
• Logic: Statements and their truth values.
• Counting principles: Determining the number of possible outcomes.
• Graphs: Visual representation of relationships.
• Trees: Special types of graphs.
• Algorithms: Step-by-step procedures for solving problems.

Number Theory

• Prime numbers: Numbers divisible only by 1 and themselves.
• Divisibility: Relationship between numbers where one is a factor of another.
• Congruence: Comparing the remainders of numbers divided by a divisor.
• Modular arithmetic: Performing arithmetic operations with remainders.
• Diophantine equations: Solving equations with integer solutions.
