About Order of Operations

The order of operations (PEMDAS) is a mathematical convention that defines the sequence in which operations should be performed in an expression with multiple operations.

PEMDAS Rule Breakdown
  1. Parentheses: Solve all expressions inside parentheses first.
  2. Exponents: Solve all exponents (powers, square roots, etc.).
  3. Multiplication and Division: Perform multiplication and division from left to right.
  4. Addition and Subtraction: Perform addition and subtraction from left to right.
Common Mistakes to Avoid
  • Solving multiplication before division (they should be done from left to right)
  • Solving addition before subtraction (they should be done from left to right)
  • Forgetting to calculate expressions in parentheses first
  • Ignoring implied multiplication (e.g., 2(3+4) means 2×(3+4))

Understanding the Order of Operations

The Order of Operations helps us know which part of a mathematical expression to solve first. It's a set of rules that ensures everyone gets the same answer when calculating. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This handy guideline is essential for tackling complex equations accurately.
