Overview of Mathematics

• Definition: A field of study involving numbers, quantities, shapes, and patterns.
• Branches:
  • Arithmetic: Basic operations (addition, subtraction, multiplication, division).
  • Algebra: Symbols and letters to represent numbers and relationships.
  • Geometry: Study of shapes, sizes, and properties of space.
  • Calculus: Study of change and motion, through derivatives and integrals.
  • Statistics: Collection, analysis, interpretation, and presentation of data.
  • Probability: Study of randomness and uncertainty.

Basic Concepts

1. Numbers:

   • Natural Numbers: Positive integers (1, 2, 3,...).
   • Whole Numbers: Natural numbers including zero (0, 1, 2,...).
   • Integers: Whole numbers and their negatives (...,-3, -2, -1, 0, 1, 2, 3,...).
   • Rational Numbers: Numbers that can be expressed as fractions (e.g., 1/2).
   • Irrational Numbers: Numbers that cannot be expressed as fractions (e.g., √2, π).

2. Operations:

   • Addition (+): Combining numbers.
   • Subtraction (−): Finding the difference between numbers.
   • Multiplication (×): Repeated addition of a number.
   • Division (÷): Splitting a number into equal parts.

3. Equations:

   • Algebraic expressions: Combinations of numbers and variables (e.g., 2x + 3).
   • Solving equations: Finding the value of the variable that makes the equation true.

Key Theorems and Principles
