Math Fundamentals Quiz

Study Notes

Numbers and Operations

Types of Numbers:
- Natural Numbers: 1, 2, 3,...
- Whole Numbers: 0, 1, 2, 3,...
- Integers:..., -3, -2, -1, 0, 1, 2, 3,...
- Rational Numbers: fractions, decimals, and percents
- Irrational Numbers: non-repeating, non-terminating decimals (e.g., π, e)
- Real Numbers: all rational and irrational numbers
Number Operations:
- Addition: combining two or more numbers to get a total or sum
- Subtraction: finding the difference between two numbers
- Multiplication: repeated addition of a number
- Division: sharing a number into equal parts or groups
- Exponents: raising a number to a power (e.g., 2^3 = 2 × 2 × 2)
- Roots: finding a value that, when multiplied by itself, gives a specified number (e.g., √16 = 4)

Algebra

Variables and Expressions:
- Variables: letters or symbols representing unknown values
- Expressions: combinations of variables, numbers, and operations
- Simplifying Expressions: combining like terms and removing parentheses
Equations and Inequalities:
- Equations: statements with equal values (e.g., 2x + 3 = 5)
- Inequalities: statements with unequal values (e.g., 2x + 3 > 5)
- Solving Equations: finding the value of the variable that makes the equation true
- Solving Inequalities: finding the range of values that make the inequality true

Geometry

Points, Lines, and Planes:
- Points: locations in space, represented by coordinates (x, y)
- Lines: sets of points extending infinitely in two directions
- Planes: flat surfaces extending infinitely in all directions
Angles and Measurements:
- Angle: formed by two rays sharing a common endpoint (vertex)
- Types of Angles: acute, right, obtuse, straight, and reflex
- Measurement Units: degrees, radians, and metric units (e.g., inches, centimeters)

Data Analysis and Statistics

Data Types:
- Qualitative Data: categorical, non-numerical data (e.g., colors, names)
- Quantitative Data: numerical data (e.g., heights, temperatures)
Data Visualization:
- Charts: bar, pie, and Pareto charts
- Graphs: line, scatter, and histogram graphs
- Plots: box and whisker plots
Measures of Central Tendency:
- Mean: average value
- Median: middle value
- Mode: most frequent value

Calculus

Limits:
- Concept of a limit: approaching a value as the input changes
- Notation: lim x→a f(x) = L
Derivatives:
- Rate of Change: measuring how a function changes as the input changes
- Notation: f'(x) or (d/dx)f(x)
Integrals:
- Accumulation of a Function: finding the total amount of change
- Notation: ∫f(x)dx or ∫[a, b] f(x)dx
