At first glance, you might rush to divide, multiply, or add in any order, but one small misstep can lead to the wrong answer. The key lies in following the correct order of operations—evaluate inside the parentheses first, then perform division and multiplication from left to right. Think you know the right result? Read on for a clear, step-by-step breakdown to see exactly why this problem often sparks lively debate and what the correct solution really is!

Common Errors
Even simple arithmetic can become tricky if you overlook the proper order of operations. Here are a few pitfalls that lead to the wrong answer:
Neglecting Parentheses
Many people dive straight into the division and multiplication without first adding the numbers inside the parentheses. That initial oversight scrambles the rest of the calculation.
Grouping Multiplication Incorrectly
Some solvers mistakenly treat “2 × (5 + 3)” as a combined unit before dividing 8. In reality, once you replace (5 + 3) with 8, you have both a division and a multiplication at the same level.
Ignoring Left‐to‐Right Rule
In expressions containing both “÷” and “×,” you must work from left to right. Failing to do so—by, for example, multiplying 2 × 8 first—produces an incorrect outcome.
Detailed Breakdown
Calculate Inside the Parentheses
- Step 1: Evaluate (5 + 3)
- (5+3)=8
- Now the equation reads:
- 8÷2×8
Perform Division and Multiplication in Order
- According to standard conventions, handle all division and multiplication as they appear from left to right.
- Step 2: First do 8 ÷ 2 = 4
- Step 3: Then do 4 × 8 = 32
Final Result
- After completing these steps, you end up with: 8÷2×(5+3)=328 ÷ 2 × (5 + 3) = 32
