Key Concepts in Mathematics
1. Branches of Mathematics
- Arithmetic: Basic operations - addition, subtraction, multiplication, division.
- Algebra: Use of symbols and letters to represent numbers and quantities in formulas and equations.
- Geometry: Study of shapes, sizes, and properties of figures and spaces.
- Calculus: Focuses on change and motion; includes derivatives and integrals.
- Statistics: Collection, analysis, interpretation, presentation of data.
- Probability: Study of uncertainty and the likelihood of events occurring.
2. Fundamental Theorems
- Pythagorean Theorem: In a right triangle, (a^2 + b^2 = c^2) (where (c) is the hypotenuse).
- Fundamental Theorem of Algebra: Every non-constant polynomial has at least one complex root.
- Fundamental Theorem of Calculus: Links differentiation and integration, providing a way to evaluate definite integrals.
3. Mathematical Operations
- Order of Operations: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right) - PEMDAS.
- Factorization: Breaking down a number or expression into multiple factors that can be multiplied together.
- Functions: Relation between a set of inputs and a set of possible outputs, defined by a rule.
4. Algebraic Concepts
- Equations: Mathematical statements that assert equality; can be linear or nonlinear.
- Inequalities: Expressions indicating the relative size or order of values.
- Polynomials: Expressions consisting of variables and coefficients, involving operations like addition, multiplication, and non-negative integer exponents.

- Types of Angles: Acute, obtuse, right, straight, reflex.
- Properties of Triangles: Sum of interior angles equals 180°, types include isosceles, equilateral, scalene.
- Circles: Key elements include radius, diameter, circumference, area ((A = \pi r^2)).
6. Calculus Concepts
- Limits: The value that a function approaches as the input approaches some value.
- Derivatives: Measure the rate of change of a quantity; slope of the tangent line to the curve.
- Integrals: Summation of areas under curves; can be definite or indefinite.
7. Statistics Fundamentals
- Mean, Median, Mode: Measures of central tendency.
- Standard Deviation: Indicates how much data varies from the mean.

Branches of Mathematics
- Arithmetic deals with basic operations like addition, subtraction, multiplication, and division.
- Algebra uses symbols and letters to represent numbers and quantities in formulas and equations.
- Geometry studies the shapes, sizes, and properties of figures and spaces.
- Calculus focuses on change and motion, including derivatives and integrals.
- Statistics involves collecting, analyzing, interpreting, and presenting data.
- Probability studies uncertainty and the likelihood of events occurring.
Fundamental Theorems
- Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides: (a^2 + b^2 = c^2).
- Fundamental Theorem of Algebra states that every non-constant polynomial with complex coefficients has at least one complex root.
- Fundamental Theorem of Calculus establishes a relationship between differentiation and integration, allowing for the evaluation of definite integrals.
Mathematical Operations
- Order of Operations is a set of rules that dictate the order in which operations should be performed in a mathematical expression. The acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) is commonly used to remember the order.
- Factorization involves breaking down a number or expression into multiple factors that can be multiplied together.
- Functions represent a relationship between a set of inputs and a set of possible outputs, defined by a rule.
Algebraic Concepts
- Equations are mathematical statements that assert equality. They can be linear (straight lines) or nonlinear (curves).
- Inequalities are expressions that indicate the relative size or order of values.
- Polynomials are expressions consisting of variables and coefficients, involving operations like addition, multiplication, and non-negative integer exponents.
Geometry Principles
- Angles can be classified as acute (less than 90 degrees), obtuse (greater than 90 degrees), right (exactly 90 degrees), straight (180 degrees), or reflex (greater than 180 degrees).
- Triangles have specific properties, including the fact that the sum of their interior angles always equals 180 degrees. Different types of triangles include isosceles (two equal sides), equilateral (all sides equal), and scalene (all sides different).
- Circles have key elements like the radius (distance from the center to the edge), diameter (distance across the circle through the center), circumference (distance around the circle), and area ((A = \pi r^2)).
Calculus Concepts
- Limits describe the value that a function approaches as the input approaches a certain value.
- Derivatives measure the rate of change of a quantity. They represent the slope of the tangent line to the curve at a specific point.
- Integrals represent the summation of areas under curves. They can be definite (with defined limits of integration) or indefinite (without specific limits).
Statistics Fundamentals
- Mean, Median, Mode are measures of central tendency, representing the average, middle value, and most frequent value in a dataset, respectively.
- Standard Deviation measures how much data varies from the mean.
