Overview of Mathematics

Definition: The study of numbers, quantities, shapes, and patterns.
Branches:
- Arithmetic: Basic operations (addition, subtraction, multiplication, division).
- Algebra: Study of symbols and rules for manipulating those symbols.
- Geometry: Study of shapes, sizes, and properties of space.
- Trigonometry: Study of relationships between angles and sides of triangles.
- Calculus: Study of change and motion; involves derivatives and integrals.
- Statistics: Study of data collection, analysis, interpretation, and presentation.
- Probability: Study of chance and uncertainty.

Numbers:
- Types: Whole numbers, integers, rational numbers, irrational numbers, real numbers, complex numbers.
Equations:
- Linear equations: Involves variables raised to the first power.
- Quadratic equations: Involves variables raised to the second power.
Functions:
- Definition: A relation where each input has a single output.
- Types: Linear, quadratic, polynomial, exponential, logarithmic.

Basic Operations:
- Addition (+)
- Subtraction (−)
- Multiplication (×)
- Division (÷)

Pythagorean Theorem: In a right triangle, a² + b² = c².
Fundamental Theorem of Algebra: Every non-constant polynomial equation has at least one complex root.
Central Limit Theorem: The distribution of sample means approaches a normal distribution as the sample size increases.

Real-world Applications:
- Engineering: Design and optimization.
- Physics: Motion, forces, energy calculations.
- Economics: Modeling financial systems and trends.
- Computer Science: Algorithms, data structures, cryptography.

Use of symbols and notation to represent mathematical ideas succinctly.
Common symbols:
- ∑ (summation)
- ∏ (product)
- ∫ (integral)
- ∆ (change/difference)

Practice regularly to strengthen problem-solving skills.
Understand concepts rather than memorizing procedures.
Utilize visual aids like graphs and diagrams for geometric and algebraic concepts.
