Are you ready to challenge your problem-solving skills with a deceptively simple mathematical puzzle? Today’s brain teaser, -8 – (3 – 8) × 2 = ?, might look like just another equation, but don’t be fooled! Many people misstep when tackling this problem due to common mistakes or overlooked details. Before you scroll down for the solution, give it a try and see if you can figure it out. What’s your final answer?
Common Mistakes When Solving Math Puzzles
Let’s face it—math puzzles can be tricky, and this one is no exception. Why do so many people get these types of problems wrong? The answer lies in small details that trip us up and the rules of math we sometimes forget. Here are some of the most common mistakes people make when solving this equation:
- Ignoring the order of operations (PEMDAS/BODMAS): One of the most frequent errors is neglecting the sequence in which operations should be performed. Multiplication and division must come before addition and subtraction, yet many solve the equation from left to right without applying this rule.
- Misinterpreting negative numbers: Working with negative numbers can feel counterintuitive, especially when they’re combined with subtraction or parentheses. People often forget to handle the signs correctly, leading to wrong answers.
- Skipping steps: Some try to solve everything in one go instead of breaking it into smaller steps. This approach increases the chance of missing a critical operation.
- Overthinking: Interestingly, simplicity can lead to overthinking. Many people second-guess themselves, assuming a straightforward solution is too easy.
Do any of these sound familiar? If so, don’t worry! We’re about to break this equation down step by step so you can master it with confidence.
Step-by-Step Guide to Solving -8 – (3 – 8) × 2
Ready to tackle the problem together? Let’s break it down logically, following the proper order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Solve inside the parentheses
The first priority is to resolve anything inside the parentheses. In this equation, we have: 3−8=−5
So now the equation becomes: −8−(−5)×2
According to the order of operations, multiplication comes next. Here, we need to multiply −5 by 2: −5×2=−10
Substitute this result back into the equation: −8−(−10)
Step 3: Handle the subtraction of a negative number
Here’s where many people trip up! Subtracting a negative number is the same as adding its positive counterpart. So: −8−(−10)=−8+10
Step 4: Perform the addition
Finally, add −8 and 10: −8+10=2
And there you have it—the correct answer is: 2
Why Does This Problem Cause So Much Confusion?
This seemingly simple problem can stump even the best of us. But why? Let’s revisit a few reasons:
- Negative numbers and double negatives: Subtracting a negative number isn’t something we encounter every day, so it’s easy to forget that it turns into addition.
- Order of operations: Many overlook the need to multiply before subtracting. This mistake can drastically change the outcome.
- Mental shortcuts: In an attempt to solve quickly, people may skip important steps or misinterpret the equation.
Recognizing these pitfalls is the first step to avoiding them. With practice, you’ll build confidence in solving problems like this one.
