Study Notes
Sets of Numbers
- Integers (ℤ): Whole numbers from negative infinity to positive infinity, including 0.
- Whole numbers (W): Non-negative whole numbers, including 0.
- Natural numbers (ℕ): Positive whole numbers, excluding 0.
Basic Operations
- Add ( + ): Find the sum.
- Subtract ( - ): Find the difference.
- Multiply ( × ): Find the product.
- Divide ( ÷ ): Find the quotient.
Order of Operations (PEMDAS)
- P: Parentheses
- E: Exponents
- M: Multiply
- D: Divide
- A: Add
- S: Subtract
Properties
- Commutative Property of Addition/Multiplication: The order of numbers does not matter for addition and multiplication.
- Example: 4 + 3 = 3 + 4 and 4 × 3 = 3 × 4
- Associative Property of Addition/Multiplication: The grouping of numbers does not matter for addition and multiplication.
- Example: (2 + 3) + 5 = 2 + (3 + 5) and (2 × 3) × 5 = 2 × (3 × 5)
