Study Notes
Arithmetic Operations
- Addition combines two or more numbers to find their sum.
- Subtraction finds the difference between two numbers.
- Multiplication is repeated addition or a shortcut for adding identical numbers.
- Division splits a number into equal parts; it's the inverse of multiplication.
Number Systems
- Natural numbers (counting numbers): 1, 2, 3,...
- Whole numbers: 0, 1, 2, 3,... (includes zero)
- Integers: ..., -3, -2, -1, 0, 1, 2, 3,... (positive and negative whole numbers, and zero).
- Rational numbers: fractions (p/q where p and q are integers, q ≠ 0), terminating decimals, and repeating decimals.
- Irrational numbers: decimals that are non-repeating and non-terminating, like √2 and π.
- Real numbers: the set of all rational and irrational numbers.
- Complex numbers: numbers of the form a + bi, where 'a' and 'b' are real numbers, and 'i' is the imaginary unit (i² = -1).
Properties of Numbers
- 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) = a × b + a × c
- Identity property: a + 0 = a, a × 1 = a
- Inverse property: a + (-a) = 0, a × (1/a) = 1 (for a ≠ 0)
Algebraic Expressions
- Variables: symbols (like x, y, or z) that represent unknown values.
- Constants: numbers without variables.
- Terms: parts of an expression separated by addition or subtraction signs.
- Expressions: combinations of variables, constants, and operations. Example: 2x + 3y - 5
Equations and Inequalities
- Equations: statements that two expressions are equal. Solving involves finding variable values that make the equation true.
- Inequalities: statements comparing expressions using symbols like <, >, ≤, ≥, ≠. Solving involves finding the range of values that make the inequality true.
Geometry
- Basic shapes: points, lines, planes, angles, triangles, quadrilaterals, circles, polygons.
- Geometric figures: two-dimensional (2D) and three-dimensional (3D) shapes.
- Perimeter: the distance around a two-dimensional shape.
- Area: the space enclosed by a two-dimensional shape.
- Volume: the space occupied by a three-dimensional shape.
- Formulas for calculating areas and perimeters of different shapes.
Measurement
- Units of measurement: standard units (e.g., meters, centimeters, kilograms, grams, liters).
- Converting between units.
- Using formulas for area and volume.
- Significant figures.
- Accuracy and precision in measurements.
Data Analysis
- Collecting data.
- Organizing data (tables, charts).
- Analyzing data (mean, median, mode, range).
- Interpreting data (charts, graphs).
Probability
- Basic concepts of probability.
- Calculating probabilities of simple events.
- Probability distributions (normal, binomial).
Statistics
- Descriptive statistics (mean, median, mode, standard deviation).
- Inferential statistics (hypothesis testing).
- Data collection methods.
Functions
- Defining a function;
- dependent variable(s), independent variable(s).
- domain, range.
- Linear functions.
- Quadratic functions.
- Exponents/logarithms.
Sets
- Sets and their elements.
- Set operations (union, intersection, difference).
