Study Notes
Arithmetic
- Definition: Branch of mathematics dealing with the basic operations of numbers: addition, subtraction, multiplication, and division.
-
Operations:
- Addition (+): Combining two numbers to get a sum.
- Subtraction (−): Finding the difference between two numbers.
- Multiplication (×): Repeated addition of a number.
- Division (÷): Distributing a number into equal parts.
-
Properties:
- Commutative: a + b = b + a; a × b = b × a
- Associative: (a + b) + c = a + (b + c); (a × b) × c = a × (b × c)
- Distributive: a × (b + c) = a × b + a × c
- Fractions: Representation of parts of a whole; includes proper, improper, and mixed numbers.
- Decimals: Another form of representing fractions using a base-10 system.
Geometry
- Definition: Study of shapes, sizes, and properties of space.
-
Basic Concepts:
- Points: Exact locations in space.
- Lines: Infinite length with no thickness, extending in two opposite directions.
- Angles: Formed by two rays (sides) with a common endpoint (vertex).
-
Shapes:
- 2D Shapes: Squares, rectangles, triangles, circles.
- 3D Shapes: Cubes, spheres, cylinders, cones.
-
Properties:
- Perimeter: The distance around a shape.
- Area: The amount of space inside a shape.
- Volume: The amount of space occupied by a 3D object.
-
Theorems:
- Pythagorean Theorem: In a right triangle, a² + b² = c² (where c is the hypotenuse).
Calculus
- Definition: Branch of mathematics focused on limits, functions, derivatives, integrals, and infinite series.
-
Key Concepts:
- Limits: The value a function approaches as the input approaches a certain point.
-
Derivatives: Measures the rate of change of a function; represents the slope of a tangent line.
- Notation: f'(x) or dy/dx.
- Rules: Power rule, product rule, quotient rule, chain rule.
-
Integrals: Represents the accumulation of quantities; can calculate areas under curves.
- Indefinite integrals: Represent a family of functions.
- Definite integrals: Calculate the exact area under a curve between two boundaries.
- Fundamental Theorem of Calculus: Connects differentiation and integration, showing that they are inverse processes.
-
Applications:
- Used in physics, engineering, economics, and statistics to model change and motion.
Arithmetic
- Branch of mathematics that handles basic number operations: addition, subtraction, multiplication, and division.
-
Operations:
- Addition combines two numbers to produce a sum.
- Subtraction determines the difference between numbers.
- Multiplication is repeated addition of a number.
- Division splits a number into equal parts.
-
Properties:
- Commutative Property: Addition and multiplication yield the same result regardless of the order (a + b = b + a; a × b = b × a).
- Associative Property: The grouping of numbers does not affect addition or multiplication ((a + b) + c = a + (b + c); (a × b) × c = a × (b × c)).
- Distributive Property: A number multiplied by a sum is equivalent to the sum of the individual products (a × (b + c) = a × b + a × c).
- Fractions: Expressions representing parts of a whole, including proper, improper, and mixed fractions.
- Decimals: Alternate representation of fractions utilizing the base-10 numeral system.

- 3D Shapes: Encompasses cubes, spheres, cylinders, and cones.
-
Properties:
- Perimeter is the total distance around a shape.
- Area measures the space within a 2D shape.
- Volume quantifies the space occupied by a 3D object.
-
