Basic Math Concepts and Number Systems

Basic Math Concepts

• Arithmetic involves basic operations: addition, subtraction, multiplication, and division.
• Algebra uses variables to represent unknowns and relationships. Solving equations is central.
• Geometry studies shapes, sizes, and positions of figures.
• Trigonometry relates angles and sides of triangles.
• Calculus deals with rates of change and accumulation, including differential and integral calculus.

Number Systems

• Natural numbers are positive integers (1, 2, 3...).
• Whole numbers include natural numbers and zero (0, 1, 2, 3...).
• Integers include whole numbers and their negatives (-3, -2, -1, 0, 1, 2, 3...).
• Rational numbers are fractions p/q (p and q are integers, q ≠ 0).
• Irrational numbers cannot be expressed as fractions. Examples are π and √2.
• Real numbers include all rational and irrational numbers.
• Imaginary numbers contain the square root of -1 (i).
• Complex numbers are of the form a + bi, where a and b are real numbers and i is the imaginary unit.

Arithmetic Operations

• Addition combines values.
• Subtraction finds the difference between values.
• Multiplication scales a value by a factor.
• Division finds how many times one value fits into another.
• Order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right).

Algebraic Equations

• Equations use an equal sign (=) to relate known and unknown values. Solving involves finding the variable's value.
• Linear equations have a variable to the power of 1.
• Quadratic equations have a variable to the power of 2.
• Systems of equations involve multiple equations. Solutions are intersection points.

Geometric Shapes

• Basic shapes include squares, rectangles, circles, triangles (equilateral, isosceles, scalene).
• Formulas exist for area and perimeter of various shapes.
• 3D shapes include cubes, spheres, cones, and cylinders, with formulas for volume and surface area.

Trigonometric Functions

• Sine, cosine, and tangent relate angles and sides of right-angled triangles.
• These functions are useful in surveying, navigation, and engineering.

Calculus Fundamentals

• Derivatives measure instantaneous rates of change.
• Integrals calculate accumulated values.
• Limits describe function behavior as a variable approaches a value.
• Derivatives and integrals are connected through the fundamental theorem of calculus.
• Calculus applications include finding maximum/minimum values, calculating areas/volumes, and modeling real-world change.

Sets and Relations

• Sets are collections of objects or numbers.
• Relations describe relationships between set elements. Ordered pairs represent relations.
• Functions are special relations where each input maps to one output.
• Domain is the set of all possible inputs.
• Range is the set of all possible outputs.

Important Mathematical Laws and Theorems

• Distributive law: a(b + c) = ab + ac
• Commutative law: a + b = b + a, a * b = b * a
• Associative law: (a + b) + c = a + (b + c), (a * b) * c = a * (b * c)
• Identity properties: Zero addition, one multiplication.
• Inverse properties: Addition (opposite), multiplication (reciprocal).
• Exponent properties (product, quotient, power rule) are key.
• Geometry theorems include triangle congruence and similarity.
