Study Notes
Whole Numbers
- Whole numbers are non-negative integers, including zero.
- Represented by the letter "W" and defined as: W = {0, 1, 2, 3, 4, 5, …}
- Example values include 0, 49, 67, 52.
Natural Numbers
- Also known as "counting numbers," starting from 1 to infinity.
- Represented by the letter "N" and defined as: N = {1, 2, 3, 4, 5, …}
- Example values include 35, 59, 110.
Integers
- Comprise both whole numbers and negative natural numbers.
- Represented by the symbol "Z" and defined as: Z = {… -3, -2, -1, 0, 1, 2, 3 …}
- Example values include -52, 0, -1, 16, 82.
Rational Numbers
- Defined as numbers that can be expressed as a fraction p/q, where p and q are integers and q ≠ 0.
- Represented by the letter "Q."
- Example fractions include 7/1, 10/2, 1/1, and 0/1.
Properties of Rational Numbers
- Closed under addition, subtraction, multiplication, and division.
- Satisfy commutative and associative properties for addition and multiplication.
- Follow the distributive property for addition and subtraction.
Properties of Whole Numbers
- Closed under addition and multiplication.
- Zero serves as the additive identity; one is the multiplicative identity.
- Complies with commutative and associative properties for addition and multiplication.
- Adheres to the distributive property of multiplication over addition and vice versa.
Properties of Integers
