What is the primary difference between rational and irrational numbers?
What is the primary difference between rational and irrational numbers?
Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot be expressed in such a form.
Explain the term 'algebraic expression' and provide an example.
Explain the term 'algebraic expression' and provide an example.
An algebraic expression involves variables and constants combined using operators. An example is $2x + 5$.

Study Notes
Fundamental Concepts
- Mathematics is a field of study focused on abstract concepts, including numbers, quantities, and shapes.
- It encompasses a broad range of subfields, such as arithmetic, algebra, geometry, calculus, and statistics.
- Mathematics is used in various disciplines, including science, engineering, computer science, and economics.
- Mathematical reasoning involves logical deduction and proofs to establish theorems and solve problems.
Number Systems
- Natural numbers (counting numbers): 1, 2, 3... Used for counting.
- Whole numbers: 0, 1, 2, 3... Include zero and natural numbers.
- Integers: ..., -3, -2, -1, 0, 1, 2, 3... Include positive and negative whole numbers.
- Rational numbers: numbers that can be expressed as a fraction p/q, where p and q are integers and q is not zero. Examples: 1/2, 3, -2/5.
- Irrational numbers: numbers that cannot be expressed as a fraction of two integers. Examples: √2, π.
- Real numbers: the set of all rational and irrational numbers.
Arithmetic Operations
- Addition (+): combining quantities.
- Subtraction (-): finding the difference between quantities.
- Multiplication (×): repeated addition.
- Division (/): finding the quotient when one quantity is divided by another.
Algebra
- Algebra uses variables to represent unknown quantities.
- Equations represent relationships between variables and constants.
- Algebraic expressions involve variables and constants combined with operators (addition, subtraction, multiplication, division).
- Solving equations involves finding the value(s) of the variable(s) that satisfy the equation.
- Inequalities represent relationships where one quantity is greater than or less than another.
Geometry
- Geometry studies shapes, sizes, and positions of figures in space.
- Basic shapes include points, lines, angles, triangles, quadrilaterals, circles, and polygons.
- Formulas exist to calculate areas, volumes, and perimeters of various shapes.
- Geometric theorems provide relationships between geometric figures.
Calculus
- Calculus deals with rates of change and accumulation of quantities.
- Differentiation calculates the rate of change of a function (derivative).
- Integration calculates the accumulation of a function (integral).
- Applications of calculus include finding slopes of curves, areas under curves, and volumes of solids.
Statistics
- Statistics deals with collecting, organizing, analyzing, and interpreting data.
- Descriptive statistics summarizes and describes data using measures of central tendency (mean, median, mode), dispersion (range, variance, standard deviation), and frequency distributions.
- Inferential statistics uses samples to draw conclusions about populations.
- Probability deals with the likelihood of events occurring.
