Study Notes
Math Fundamentals
- Basic Arithmetic Operations: Addition, subtraction, multiplication, and division are fundamental mathematical operations. Understanding these is crucial for more complex problems.
- Order of Operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right) determines the calculation sequence.
- Sets and Numbers: Different types of numbers (natural, integers, rational, irrational, real) have unique characteristics. Understanding these sets is vital for algebra and mathematics.
Algebra
- Variables and Expressions: Letters (variables) represent unknown quantities in algebra. Expressions combine variables, numbers, and operators.
- Equations and Inequalities: Equations show equality, inequalities demonstrate relationships like greater than or less than. Solving equations finds the variable's value.
- Linear Equations: Equations with a variable's highest power of 1, commonly graphed as straight lines. They show relationships between two variables.
- Systems of Equations: Multiple linear equations are solved simultaneously to find values that satisfy all equations.
- Polynomials: Expressions with variables raised to non-negative integer powers, combined with coefficients and constants.
- Factoring: Simplifying polynomials by breaking them down into simpler expressions.
- Quadratic Equations: Equations with a variable's highest power of 2. Solutions can be found via the quadratic formula or factoring.
Mensuration
- Geometric Shapes: Understanding shape properties (triangles, squares, circles, cubes, cylinders) is crucial.
- Area: Enclosed two-dimensional space measured using formulas specific to shapes.
- Perimeter: The total distance around a two-dimensional shape.
- Volume: The space occupied by a three-dimensional object, calculated using specific formulas.
- Surface Area: The combined area of all surfaces on a three-dimensional object.
Power and Exponents
- Exponents: A concise way to represent repeated multiplication (e.g., 23 = 2 x 2 x 2).
- Base: The number being repeatedly multiplied.
- Exponent: The number showing how many times the base is multiplied by itself.
- Laws of Exponents: Rules for simplifying and solving exponent expressions (multiplication, division, powers of powers, negative exponents).
- Zero Exponent: Any non-zero number to the power of zero equals 1.
- Negative Exponents: Negative exponents represent reciprocals (1/base|exponent|).
- Scientific Notation: A method expressing very large or very small numbers using powers of 10.
- Applications of Powers and Exponents: Used in numerous scientific and mathematical contexts (compound interest, growth modeling, measuring very large or very small quantities).
