Overview of Mathematics

Mathematics is the study of numbers, quantities, structures, and changes.
It consists of various branches including arithmetic, algebra, geometry, calculus, and statistics.

Arithmetic
- Deals with basic operations: addition, subtraction, multiplication, division.
- Involves the study of numbers and their properties.
Algebra
- Focuses on symbols and the rules for manipulating those symbols.
- Includes solving equations, using variables, and functions.
Geometry
- Studies shapes, sizes, relative positions, and properties of space.
- Key concepts include points, lines, angles, surfaces, and solids.
Calculus
- Concerns rates of change (differentiation) and accumulation of quantities (integration).
- Fundamental theorems connect differentiation and integration.
Statistics
- Involves collecting, analyzing, interpreting, and presenting data.
- Key concepts include mean, median, mode, standard deviation, and probability.

Number Systems
- Natural Numbers, Whole Numbers, Integers, Rational Numbers, Irrational Numbers, Real Numbers, Complex Numbers.
Functions
- A relation that assigns a unique output for every input.
- Types include linear, quadratic, polynomial, exponential, and logarithmic functions.
Equations and Inequalities
- Equations express the equality of two expressions.
- Inequalities indicate the relative sizes of two values.

Understanding the Problem
- Read carefully, identify known and unknown variables, and clarify the goal.
Devising a Plan
- Choose strategies like drawing diagrams, working backward, or simplifying the problem.
Carrying Out the Plan
- Execute selected strategies step by step, maintaining clear notation.
Reviewing/Checking the Solution
- Verify results by substituting back into the original problem or analyzing the solution’s reasonableness.

Algebra focuses on symbols and their manipulation rules, involving solving equations, using variables, and exploring functions.
Geometry investigates shapes, sizes, relative positions, and properties of space, incorporating points, lines, angles, surfaces, and solids.
Calculus focuses on rates of change (differentiation) and accumulation of quantities (integration), linking both through fundamental theorems.
Statistics involves collecting, analyzing, interpreting, and presenting data, utilizing key concepts such as mean, median, mode, standard deviation, and probability.

Number Systems encompass various number types:
- Natural Numbers (1, 2, 3,...)
- Whole Numbers (0, 1, 2, 3,...)
- Integers (...-3, -2, -1, 0, 1, 2, 3,...)
- Rational Numbers (fractions and decimals that terminate or repeat)
- Irrational Numbers (decimals that do not terminate or repeat)
- Real Numbers (all rational and irrational numbers)
- Complex Numbers (numbers expressed as a+bi, where 'i' is the imaginary unit).
Functions are relations that assign a unique output to every input. They can be categorized as linear, quadratic, polynomial, exponential, and logarithmic functions.
Equations and Inequalities express the equality or relative sizes of two values. Equations establish equality, while inequalities indicate relative sizes.
