Study Notes
Definition of Rational Numbers
- A rational number is defined as any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
- Examples include numbers like 1/2, -3, and 4.75.
Branch of Mathematics
- The branch of mathematics that extensively utilizes rational numbers is called Algebra.
- Algebra analyzes relationships involving rational numbers through equations, functions, and expressions.
Composition of Algebraic Expressions
- Algebraic expressions are comprised of variables, constants, and mathematical operators (such as addition, subtraction, multiplication, and division).
- They can include terms with coefficients and exponents, like 3x² - 2x + 1.
Structure of Mathematical Expressions
- Mathematical expressions are formed from numbers, variables, and operators, which can be combined to represent quantities and relationships.
- Types of expressions include numerical expressions (like 5 + 3) and algebraic expressions (like 2x - 4).
Collection of Rational Numbers
- The collection of rational numbers, often denoted as Q, includes all fractions and integers, allowing various applications such as in ratio problems, probability, and statistics.
- Rational numbers are essential in contexts where precise calculations are necessary, such as engineering and finance.
