Presenting the Puzzle: Think You’ve Got It?

Alright, it’s time for the main event! Below is the viral math puzzle that’s been causing a stir across the internet. Take a good look, grab a pen and paper if you like, and try to solve it on your own before you scroll down. Remember, the key is not just to get an answer, but to get the *right* answer!

The Viral Math Problem:

48 ÷ 6 + 5 × 2 − 7

Here are the choices that were often presented with the puzzle:

• A. 15
• B. 13
• C. 9
• D. 1

Take a moment. What’s your answer? Don’t rush! This is where the ‘trick’ often lies. Once you have your solution, keep it in mind as we dive into the rules that govern such equations.

What Exactly Is PEMDAS (or BODMAS)?

Before we reveal the solution, let’s talk about the secret weapon you need to solve this puzzle (and any similar math problem) correctly: the order of operations. This is a set of rules that dictates the sequence in which mathematical operations should be performed to ensure a consistent and correct result. Without it, everyone could get a different answer!

You might know it as PEMDAS or BODMAS, depending on where you learned your math. Both acronyms represent the same rules, just with slightly different names for ‘parentheses’ and ‘exponents’.

PEMDAS stands for:

• Parentheses (or Brackets)
• Exponents (or Orders/Indices)
• Multiplication
• Division
• Addition
• Subtraction

BODMAS stands for:

• Brackets
• Orders (powers/indices)
• Division
• Multiplication
• Addition
• Subtraction

The crucial part to remember is that Multiplication and Division have equal priority and should be performed from left to right. The same applies to Addition and Subtraction – they also have equal priority and are performed from left to right after multiplication and division are complete.

Step-by-Step Solution: Unpacking the Viral Math Puzzle

Now that we’ve refreshed our memory on PEMDAS, let’s apply it step-by-step to our viral puzzle:

The Equation: 48 ÷ 6 + 5 × 2 − 7

Step 1: Parentheses/Brackets? Exponents/Orders?

Looking at our equation, we don’t have any parentheses or exponents. So, we move on to the next step.

Step 2: Multiplication and Division (from left to right)

We perform all multiplication and division operations as they appear from left to right.

• First, we see 48 ÷ 6.
• 48 ÷ 6 = 8

Our equation now looks like this: 8 + 5 × 2 − 7

• Next, we see 5 × 2.
• 5 × 2 = 10

Our equation now becomes: 8 + 10 − 7

Step 3: Addition and Subtraction (from left to right)

Now, we perform all addition and subtraction operations as they appear from left to right.

• First, we see 8 + 10.
• 8 + 10 = 18

Our equation is now: 18 − 7

• Finally, we have 18 − 7.
• 18 − 7 = 11

Why the Correct Answer Is 11 (And Why the Choices Were Tricky!)

And there you have it! Following the order of operations (PEMDAS/BODMAS) meticulously, the only correct answer to the puzzle 48 ÷ 6 + 5 × 2 − 7 is 11.

You might have noticed that 11 was NOT one of the choices provided in the original viral puzzle. This is a common tactic in these types of online challenges – sometimes, the options are deliberately incorrect to further emphasize the importance of understanding the rules, or simply to create more discussion and engagement. It’s a clever way to ensure people really stop and think, and perhaps even learn something new or reinforce what they already know!

Decoding the Incorrect Choices: Where Did They Go Wrong?

Let’s take a look at the provided (incorrect) choices and understand how someone might arrive at them by not following PEMDAS:

Choice A: 15

How someone might get 15:

1. Maybe they did addition first: 6 + 5 = 11.
2. Then division: 48 ÷ 11 ≈ 4.36 (already wrong path).
3. Or perhaps they did things strictly left-to-right without respecting operator priority:
   • 48 ÷ 6 = 8
   • 8 + 5 = 13
   • 13 × 2 = 26 (oops, still not 15)
4. Another common mistake leading to 15 could be doing `5 * 2 = 10`, `6 + 10 = 16`, `48 / 16 = 3`, `3 – 7 = -4`.
5. It’s possible they did `48 / 6 = 8`, `5 * 2 = 10`. Then `8 + 10 – 7`. If they did `10 – 7 = 3`, then `8 + 3 = 11`. This is the correct path. So, how to get 15? If they tried `(6+5) = 11`, `(2-7) = -5`, then `48/11 + -5`. This is highly unlikely.

The most common way people get incorrect answers is by doing operations strictly from left to right without respecting the hierarchy. For 15, let’s explore this path again:

• 48 ÷ 6 = 8
• 8 + 5 = 13
• 13 × 2 = 26
• 26 − 7 = 19

Still not 15. This suggests that the choices themselves might stem from a completely different problem or very specific, unusual misinterpretations. However, typically, mistakes arise from incorrect sequencing of operations.

Let’s assume a simplified mistake for 15:

• If someone did `6 + 5 = 11` *before* division: `48 / 11` (doesn’t work out neatly).
• If someone did `5 * 2 = 10`, then `6 + 10 = 16`, then `48 / 16 = 3`. And if they incorrectly then did `3 + 7 = 10` (instead of `-7`), this isn’t 15 either.

The difficulty in reverse-engineering 15, 13, 9, or 1 from typical PEMDAS errors strongly suggests these choices were arbitrary or from a slightly different puzzle. Let’s focus on the *type* of errors instead of specific paths to these exact numbers.

The Most Common Error: Strict Left-to-Right Calculation

Many people forget that multiplication and division (and addition and subtraction) don’t simply go left-to-right *always*. They go left-to-right *within their priority level*. The most common mistake is to treat all operations equally from left to right:

1. 48 ÷ 6 = 8
2. 8 + 5 = 13
3. 13 × 2 = 26
4. 26 − 7 = 19 (This is a very common incorrect answer if PEMDAS is ignored)

So, the options given (15, 13, 9, 1) are not even the most common incorrect answer that results from simply going left-to-right. This reinforces the idea that the choices might have been arbitrary, making the puzzle even trickier by not even providing the
