Study Notes
Key Concepts in Mathematics
1. Basic Arithmetic
- Addition: Combining two or more numbers.
- Subtraction: Finding the difference between numbers.
- Multiplication: Repeated addition of a number.
- Division: Splitting a number into equal parts.
2. Algebra
- Variables: Symbols representing unknown values (e.g., x, y).
- Equations: Mathematical statements that assert the equality of two expressions (e.g., 2x + 3 = 7).
- Functions: Relations that assign exactly one output for each input (e.g., f(x) = x^2).
3. Geometry
- Shapes: Basic forms like squares, circles, and triangles.
- Theorems: Statements that can be proven (e.g., Pythagorean theorem).
- Angles: Measured in degrees; types include acute, right, and obtuse.
4. Trigonometry
- Sine, Cosine, Tangent: Ratios related to the angles in right triangles.
- Unit Circle: A circle with radius 1 used to define trigonometric functions.
5. Calculus
- Limits: The value a function approaches as the input approaches a certain point.
- Derivatives: Measures the rate of change of a function.
- Integrals: Represents the accumulation of quantities, commonly used for area under curves.
6. Statistics
- Mean: Average of a set of numbers.
- Median: Middle value when numbers are arranged in order.
- Mode: The value that occurs most frequently in a data set.
7. Probability
- Event: A result or outcome (e.g., rolling a die).
- Probability: Likelihood of an event occurring, expressed as a number between 0 and 1.
8. Number Theory
- Prime Numbers: Numbers greater than 1 that have no positive divisors other than 1 and themselves.
- Factors: Numbers that divide another number without leaving a remainder.
9. Mathematical Notation
- Symbols: Common symbols include + (addition), - (subtraction), × (multiplication), ÷ (division), = (equals), and ≠ (not equal).
Important Properties
- Commutative Property: a + b = b + a, a × b = b × a
- Associative Property: (a + b) + c = a + (b + c), (a × b) × c = a × (b × c)
- Distributive Property: a(b + c) = ab + ac
Mathematical Problem-Solving Strategies
- Understand the Problem: Read carefully and identify knowns and unknowns.
- Develop a Plan: Choose strategies or formulas to apply.
- Implement the Plan: Carry out the calculations step-by-step.
- Review/Check: Ensure the solution makes sense and is reasonable.

Important Properties
-
Commutative Property - The order of elements doesn't affect the result:
- a + b = b + a
- a × b = b × a
-
Associative Property - Grouping of elements doesn't affect the result:
- (a + b) + c = a + (b + c)
- (a × b) × c = a × (b × c)
-
Distributive Property - Multiplication distributes over addition:
- a (b + c) = ab + ac
