Arithmetic

• Basic Operations: Addition, subtraction, multiplication, and division are fundamental operations in mathematics.
• Order of Operations: PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction) are acronyms used to remember the order in which mathematical operations should be performed.

Algebra

• Variables: Symbols like x or y represent unknown numbers in algebraic expressions.
• Equations: A mathematical statement like 2x + 3 = 7 expresses equality between two expressions.
• Functions: They describe relationships between sets of numbers, often written as f(x), meaning a function f applied to the variable x.
• Quadratic Equations: Equations in the form ax² + bx + c = 0 can be solved using the quadratic formula to find their solutions.

Geometry

• Shapes and Properties:
  • Triangle: The sum of angles in any triangle is always 180°. The area of a triangle is calculated as 1/2 * base * height.
  • Rectangle: The area of a rectangle is found by multiplying its length and width (length * width). The perimeter is twice the sum of its length and width (2(length + width)).
  • Circle: The area of a circle is calculated using the formula πr² where r is the radius. The circumference of a circle is 2πr.
• Theorems: The Pythagorean theorem applies to right-angled triangles, stating that the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a² + b² = c²).

Trigonometry

• Basic Functions: Sine (sin), Cosine (cos), and Tangent (tan) are the primary trigonometric functions.
• Relationships: These functions are related through the equation sin²θ + cos²θ = 1. Additionally, the tangent function can be expressed as tanθ = sinθ/cosθ.
• Applications: Trigonometry is used to determine angles and distances within right-angled triangles, solving problems in various fields like surveying and navigation.

Calculus

• Derivatives: They measure the rate of change of a function at a specific point. Derivatives are used to find slopes of lines tangent to curves and rates of change.
• Integrals: The concept of an integral represents the area under a curve. Integrals help calculate accumulated quantities and total values.
• Fundamental Theorem of Calculus: This fundamental theorem establishes a close relationship between differentiation (finding derivatives) and integration.

Statistics

• Data Types:
  • Qualitative: Categorical data, describing qualities or characteristics (e.g., colors, types).
  • Quantitative: Numerical data, representing amounts or measurements (e.g., height, weight).
• Measures of Central Tendency: Mean, median, and mode are measures used to find the central or typical value within a dataset.
• Probability: The likelihood of an event occurring is calculated as the ratio of favorable outcomes to the total possible outcomes.

Number Theory

• Prime Numbers: Greater than 1, prime numbers are only divisible by 1 and themselves (e.g., 2, 3, 5, 7, 11).
• Factors and Multiples: Factors divide evenly into a number, while multiples are results of multiplying a number by an integer.

Mathematical Logic

• Statements: Propositions that can be determined as either true or false.
• Logical Connectives: Words like "AND", "OR", and "NOT" connect simpler statements to form more complex statements.
• Proofs: Methods for demonstrating the truth of mathematical statements. Common proof techniques include direct proof, proof by contradiction, and proof by mathematical induction.
