Order of Operations - Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction (PEMDAS)
Objective: I know how to perform mixed operations with parenthesis, exponents, multiplication, division, addition, and subtraction.
If the calculations involve a combination of parenthesis, exponents, multiplication, division, addition, and subtraction then Step 1: First, perform the operations within the parenthesis Step 2: Second, evaluate the exponents. Step 3: Third, perform multiplication and division from left to right. Step 4: Fourth, perform addition and subtraction from left to right.
Example: Calculate 23 – 3 × (8 – 6) =
Solution: 23 – 3 × (8 – 6) (perform within parenthesis) = 23 – 3 × 2 (evaluate the exponent) = 8 – 3 × 2(perform multiplication) = 8 – 6 (perform subtraction) = 2
