    Study Notes

    Order of Operations

    Definition

    The Order of Operations is a set of rules used to evaluate mathematical expressions in the correct order.

    Acronym

    The acronym PEMDAS is commonly used to remember the correct order:

    1. Parentheses: Evaluate expressions inside parentheses first.
    2. Exponents: Evaluate any exponential expressions next (e.g., 2^3).
    3. Multiplication and Division: Evaluate from left to right.
    4. Addition and Subtraction: Evaluate from left to right.

    Examples

    • 2 × 3 + 10 - 5 = ?
      • Evaluate multiplication and division (from left to right): 2 × 3 = 6
      • Evaluate addition and subtraction (from left to right): 6 + 10 = 16, 16 - 5 = 11
      • Final answer: 11
    • 10 - 3 + 2 × 4 = ?
      • Evaluate multiplication and division (from left to right): 2 × 4 = 8
      • Evaluate addition and subtraction (from left to right): 10 - 3 = 7, 7 + 8 = 15
      • Final answer: 15
