Mathematics Fundamentals and Number Systems

Fundamental Concepts

• Mathematics is a broad field encompassing various branches such as algebra, geometry, calculus, and statistics.
• It deals with abstract concepts like numbers, shapes, and logic to solve problems and model real-world phenomena.
• Mathematical concepts are fundamental to many other fields like science, engineering, and computer science.

Number Systems

• Natural numbers (counting numbers): 1, 2, 3,...
• Whole numbers: 0, 1, 2, 3,...
• Integers: ..., -3, -2, -1, 0, 1, 2, 3,...
• Rational numbers: numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero.
• Irrational numbers: numbers that cannot be expressed as a fraction. Examples include π (pi) and √2.
• Real numbers: the set of all rational and irrational numbers.
• Complex numbers: numbers that can be expressed in the form a + bi, where a and b are real numbers, and i is the imaginary unit (√-1).

Arithmetic Operations

• Addition (+): combining two or more quantities.
• Subtraction (-): finding the difference between two quantities.
• Multiplication (×): repeated addition.
• Division (÷): repeated subtraction or finding how many times one quantity is contained in another.
• Exponents: repeated multiplication.
• Roots (√): the inverse of exponents.

Algebra

• Variables: symbols that represent unknown quantities.
• Equations: statements that show the equality of expressions.
• Inequalities: statements that show the relationship between expressions (e.g., <, >, ≤, ≥).
• Polynomials: expressions consisting of variables and coefficients.
• Factoring: expressing a polynomial as a product of simpler expressions.
• Solving equations: finding the values of variables that make an equation true.

Geometry

• Shapes and figures: lines, angles, triangles, quadrilaterals, circles, and solids.
• Measurement: finding the length, area, volume of geometric figures.
• Transformations: reflections, rotations, translations, and dilations.
• Constructions: creating geometric figures using tools like a compass and straightedge.

Calculus

• Limits: the behavior of a function as its input approaches a specific value.
• Derivatives: the rate of change of a function.
• Integrals: the accumulation of a function over an interval.
• Applications: modelling physical phenomena using rates of change and accumulation.

Statistics

• Data collection and organization: collecting, classifying, and displaying data.
• Measures of central tendency: mean, median, and mode.
• Measures of dispersion: range, variance, and standard deviation.
• Probability: the likelihood of an event occurring.
• Statistical inference: drawing conclusions about a population based on a sample.

Logic

• Statements and propositions: declarative sentences that can be true or false.
• Connectives: and, or, not, if-then.
• Logical arguments: reasoning based on statements and connectives.
• Implications and deductions: drawing conclusions from given premises.
