Study Notes
Overview of Mathematics
- Definition: The study of numbers, quantities, shapes, and patterns.
-
Branches of Mathematics:
- Arithmetic: Basic operations (addition, subtraction, multiplication, division).
- Algebra: Symbols and letters to represent numbers in equations.
- Geometry: Study of shapes, sizes, and properties of space.
- Calculus: Study of change and motion; involves derivatives and integrals.
- Statistics: Analyzing data to make inferences and predictions.
Fundamental Concepts
-
Numbers:
- Natural Numbers: Counting numbers (1, 2, 3, ...).
- Integers: Whole numbers, both positive and negative (..., -2, -1, 0, 1, 2, ...).
- Rational Numbers: Numbers that can be expressed as fractions (e.g., 1/2, 2/3).
- Irrational Numbers: Numbers that cannot be expressed as fractions (e.g., π, √2).
-
Operations:
- Addition (+): Combining quantities.
- Subtraction (−): Finding the difference between quantities.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Splitting a quantity into equal parts.
Key Theorems and Principles
