Arithmetic

• Basic operations include addition, subtraction, multiplication, and division.
• Key properties include commutative, associative, and distributive.
• Order of operations is commonly remembered using mnemonics like PEMDAS or BODMAS.

Algebra

• Variables represent unknown values, while constants are fixed.
• Coefficients are numbers multiplied by variables.
• Solving linear equations and inequalities involves isolating the variable.
• Quadratic equations have a term with the variable squared and can be solved using the quadratic formula.

Geometry

• Common shapes studied include triangles, quadrilaterals, circles, and polygons.
• Key properties include area, perimeter, and volume, which are calculated based on specific formulas.
• Important theorems include the Pythagorean theorem, which relates the sides of a right triangle, and properties of angles, such as the fact that the angles in a triangle add up to 180 degrees.

Trigonometry

• Trigonometric functions relate angles and sides in right triangles.
• The unit circle helps visualize angles and their trigonometric values.
• Trigonometric identities and equations are used for manipulating and solving problems involving trigonometric functions.

Calculus

• Differentiation involves finding the derivative, which represents the rate of change of a function.
• Integration calculates the area under a curve, also known as the definite integral.
• Calculus has many applications including finding rates of change and calculating areas.

Statistics

• Data can be classified as qualitative or quantitative.
• Measures of central tendency include the mean (average), median (middle value), and mode (most frequent value).
• Measures of dispersion show how spread out data is, like range (difference between highest and lowest), variance, and standard deviation.
• Probability deals with the likelihood of events and explores distributions like the normal and binomial.

Discrete Mathematics

• Set theory explores sets, which are collections of objects, and functions, which map elements from one set to another.
• Combinatorics deals with arranging and counting objects, including permutations (arrangements where order matters) and combinations (groups where order doesn't matter).
• Graph theory studies networks of points connected by lines, called vertices and edges, and analyzes paths and connections.

Mathematical Reasoning

• Logic uses propositions (statements that can be true or false) and logical operators (like "and", "or", "not") to reason about relationships.
• Proof techniques are used to demonstrate the validity of mathematical statements, common techniques include direct proof, proof by contradiction, and mathematical induction.

Number Theory

• Prime numbers are natural numbers greater than 1 that are only divisible by 1 and themselves.
• Divisibility rules help determine if a number is divisible by another, and the greatest common divisor (GCD) is the largest number that divides two or more numbers.
• Modular arithmetic involves computing remainders after division.

Functions

• Functions represent the relationship between input and output values.
• Common types include linear, quadratic, exponential, and logarithmic.
