Basic Arithmetic and Number Systems Quiz

Basic Arithmetic Operations

• Addition involves combining two or more numbers to find their total.
• Subtraction involves finding the difference between two numbers.
• Multiplication involves repeatedly adding a number to itself a specific number of times.
• Division involves splitting a number into equal parts.

Number Systems

• Natural numbers are positive whole numbers (1, 2, 3...).
• Whole numbers include zero and positive whole numbers (0, 1, 2, 3...).
• Integers include zero, positive whole numbers, and negative whole numbers (...-2, -1, 0, 1, 2...).
• Rational numbers can be expressed as a fraction p/q where p and q are integers, and q is not zero.
• Irrational numbers cannot be expressed as a fraction.
• Real numbers include all rational and irrational numbers.
• Imaginary numbers are numbers that, when squared, result in a negative number.

Algebra

• Variables represent unknown quantities.
• Equations state that two expressions are equal.
• Inequalities show a relationship where one expression is greater than or less than another.
• Linear equations represent a straight line on a graph.
• Quadratic equations involve a variable raised to the second power.
• Exponents represent repeated multiplication.
• Polynomials are expressions involving variables and their exponents.

Geometry

• Points are locations in space.
• Lines are straight paths extending infinitely in two directions.
• Angles are the space between two intersecting lines.
• Triangles have three sides and three angles.
• Polygons are two-dimensional shapes with straight sides.
• Circles are perfectly round shapes.
• Area measures the space inside a two-dimensional shape.
• Perimeter measures the distance around a two-dimensional shape.
• Volume measures the space occupied by a three-dimensional object.
• Solid figures are three-dimensional shapes.

Measurement

• Units of measurement are used to quantify physical quantities.
• Standard units are used for consistency.
• Common units include meters, centimeters, kilometers, grams, kilograms, liters, seconds, minutes, hours.

Data Analysis

• Data collection involves gathering information.
• Data organization involves arranging data in a structured way.
• Data presentation involves displaying data in charts, graphs, or tables.
• Data interpretation involves analyzing data to derive insights.
• Measures of central tendency (e.g., mean, median, mode) summarize data.
• Measures of variability (e.g., range, standard deviation) describe the spread of data.

Statistics

• Statistics is the science of collecting, organizing, analyzing, interpreting, and presenting data.
• Frequency distributions show how often different values occur.
• Probability measures the likelihood of an event happening.
• Samples are representative portions of a population.
• Populations are the entire group being studied.

Functions

• A function assigns exactly one output value to each input value.
• Functions can be represented graphically, with tables, or algebraically with equations.
• Linear functions produce a straight line on a graph and often follow the form y = mx + b.
• Quadratic functions form a parabola on a graph and usually follow the form y = ax² + bx + c.
• Exponential functions involve an exponent and can often show growth or decay.
• Logarithmic functions are the inverse of exponential functions.

Trigonometry

• Trigonometry deals with relationships between angles and sides of triangles.
• Trigonometric functions (sin, cos, tan) relate angles and sides.
• Applications of trigonometry are common in surveying, navigation, and engineering.

Calculus

• Calculus studies change and accumulation.
• Differential calculus deals with rates of change (derivatives).
• Integral calculus deals with accumulation of quantities (integrals).
• Applications include calculating areas, volumes, and velocities.
