Can you solve this math puzzle

Have you ever come across a math problem that seems easy at first glance, only to realize that most people get it wrong? The equation 9 – 9 ÷ 9 + 9 – 9 ÷ 9 = ? is one such puzzle that confuses many. It looks simple, but if you’re not careful, you might end up with the wrong answer.

Are you ready to put your math skills to the test? Take a moment to solve it before reading ahead. Think you got it right? Let’s find out!

Why Do So Many People Get This Wrong?

At first glance, this equation appears straightforward. However, small details in mathematical rules trip people up. Here are some common mistakes that lead to the wrong answer:

  1. Ignoring the Order of Operations (PEMDAS/BODMAS) – Many people solve the problem from left to right without following the correct order of operations.
  2. Misplacing Parentheses (Even When They Aren’t Written) – Some assume parentheses where there are none, changing how they approach division and subtraction.
  3. Rushing Through the Calculation – The problem is designed to look easy, so people tend to solve it quickly and overlook critical steps.

So, what’s the correct approach? Let’s break it down step by step.

Step-by-Step Solution

To solve this equation correctly, we must follow the order of operations. The most commonly used rule is PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

The given equation:
9 – 9 ÷ 9 + 9 – 9 ÷ 9

Step 1: Solve the Division First

According to PEMDAS, division comes before subtraction and addition. So, let’s divide first:

  • 9÷9=19 ÷ 9 = 19÷9=1
  • 9÷9=19 ÷ 9 = 19÷9=1

Now, substitute these values back into the equation:

9 – 1 + 9 – 1

Step 2: Perform Addition and Subtraction from Left to Right

Now, we calculate in order from left to right:

  • 9 – 1 = 8
  • 8 + 9 = 17
  • 17 – 1 = 16

So, the correct answer is: 16

Common Incorrect Answers and Why They Happen

Many people arrive at incorrect answers because they don’t follow the correct order of operations. Here are some of the most common mistakes:

  • Answer: 0 – This happens when someone groups all the numbers together without following PEMDAS, incorrectly simplifying the problem as:
    9−9−9+9−9=09 – 9 – 9 + 9 – 9 = 09−9−9+9−9=0
  • Answer: 1 – Some mistakenly subtract 9 from itself first before dividing, leading to:
    (9−9)÷9+9−9÷9=1(9 – 9) ÷ 9 + 9 – 9 ÷ 9 = 1(9−9)÷9+9−9÷9=1

These errors reinforce the importance of following the correct mathematical rules step by step.

Why Understanding Order of Operations Matters

You might wonder—why does it even matter? Well, mathematics is built on logical rules, and following them correctly ensures we get consistent, accurate answers. The order of operations is used in everything from programming to engineering to everyday calculations.

I BURIED MY WIFE 20 YEARS AGO — YESTERDAY, SHE LITERALLY SAVED ME FROM A STROKE.

The rain hammered against the windshield, mirroring the storm raging inside me. It had been a year since the accident. A year since my wife, Emily, had vanished without a trace. The car, a mangled wreck, had been discovered at the edge of the Blackwood Forest, a chilling reminder of the day my world shattered.

The police had searched tirelessly, but to no avail. Volunteers combed the forest, their faces etched with sympathy, but their efforts yielded nothing. The prevailing theory, grim as it was, was that wild animals had taken her.

Emily’s mother, a woman of unwavering faith, had insisted on a funeral. “We need closure,” she’d said, her voice thick with grief. And so, we gathered, surrounded by the somber silence of the cemetery, to mourn a life cut tragically short.

But grief, it turned out, was a stubborn beast. It clung to me, a persistent shadow that followed me everywhere. I couldn’t escape the haunting memories – Emily’s laughter, the way she smelled of lavender, the warmth of her hand in mine.

And then, a few days ago, the unthinkable happened. I was at the local cafe, enjoying a much-needed cup of coffee, when a sudden wave of dizziness washed over me. The world tilted, the warm coffee spilling across the table. I slumped to the floor, the taste of bitter coffee and fear filling my mouth.

Panic surged through me as I struggled to breathe. Then, I felt a gentle hand on my shoulder. “Sir, are you alright?” a concerned voice asked.

As I tried to focus, a face swam into view. It was a woman, her eyes wide with concern. “Can you pronounce this word for me?” she asked, her voice clear and calm. “Apple.”

I managed a slurred “Apple.”

“Good. Now, can you lift your right hand?”

I tried, but my arm felt heavy, unresponsive. Fear, cold and clammy, gripped me. What was happening?

Then, as my vision cleared, I saw her. Her face, pale and drawn, framed by a tangled mass of hair. The same captivating blue eyes, the same mischievous glint in their depths. And there it was, unmistakable, the crescent-shaped birthmark on the left side of her forehead.

It couldn’t be. It couldn’t be Emily.

But it was.

She looked at me, a mixture of disbelief and fear in her eyes. “Ronald?” she whispered, her voice hoarse.

The world seemed to tilt on its axis once more. I couldn’t speak, couldn’t move. All I could do was stare at her, at the face I thought I had lost forever.

How? How could she be alive? Where had she been all this time?

Questions swirled in my mind, a chaotic whirlwind of disbelief and joy. But one thing was certain: Emily was alive. And after a year of despair, hope had finally returned, brighter than any sunrise. The rain hammered against the windows, mirroring the storm raging inside me. It had been six months since the accident. Six months since my wife, Emily, had vanished without a trace. Her car, mangled and abandoned, had been discovered at the edge of the Blackwood Forest, a place where legends of the supernatural mingled with tales of real danger.

The police had searched tirelessly, their efforts joined by a tireless band of volunteers. But all their efforts yielded nothing. No trace of Emily. Just the mangled car, a chilling testament to the tragedy.

Emily’s mother, a woman of unwavering faith, insisted on a funeral. “We need closure,” she had said, her voice thick with grief. And so, we gathered, a small circle of mourners, to say goodbye to the woman I loved. It was a heartbreaking ceremony, a hollow echo of the life we were supposed to build together.

Life without Emily felt surreal. The house, once filled with her laughter and the clatter of her cooking, was now eerily silent. Every corner whispered her name, every familiar scent a haunting reminder of her absence. I spent my days adrift, haunted by the “what ifs,” the “if onlys.”

Then, came that fateful morning. I was at the local cafe, the rain mirroring the grey haze that had settled over my life. As I reached for my coffee, the world tilted. A wave of dizziness washed over me, and I crumpled to the floor, the hot coffee spilling across the table.

Suddenly, a pair of hands gripped my shoulders, steadying me. “Sir, are you alright?” A voice, concerned yet firm. I tried to focus, my vision blurring. Then, I saw her.

Her face, pale and drawn, was inches from mine. And there it was – the unmistakable birthmark on the left side of her forehead, a small crescent moon that I had kissed countless times.

Emily.

My breath hitched. “Emily?” I croaked, my voice hoarse.

Her eyes, wide with a mixture of shock and disbelief, met mine. “John?”

The world seemed to tilt again, this time with a dizzying sense of disbelief. How? How was she alive?

“I… I don’t understand,” I stammered, my voice trembling.

She looked around, her gaze landing on the concerned faces of the cafe patrons. “I… I can’t explain,” she whispered, her voice weak. “I woke up… somewhere. I don’t remember much. I was hurt, disoriented. I… I wandered for days.”

A flood of questions surged through me. Where had she been? What had happened? How had she survived? But before I could ask, she fainted.

As the paramedics rushed her to the hospital, I felt a surge of hope, a flicker of joy that I hadn’t felt in months. Emily was alive. She was here.

The days that followed were a whirlwind of medical tests, cautious questions, and whispered reassurances. Emily slowly regained her strength, her memory returning in fragments. She remembered the accident, the terrifying crash, the darkness that followed. She remembered waking up in a strange place, disoriented and alone, with no memory of how she got there. She had wandered for days, lost and terrified, surviving on berries and rainwater.

The mystery of her disappearance remained unsolved. The police were baffled, the medical professionals amazed. But none of that mattered anymore. All that mattered was that she was alive, that she was back in my arms.

Life after that was a slow, tentative journey back to normalcy. We faced countless questions, whispers, and curious stares. But we faced them together, hand in hand, cherishing every moment. The fear of losing her had cast a long shadow over our lives, but now, we clung to each other, determined to make the most of every precious day.

The accident had changed us, forever altering the course of our lives. But it had also taught us the true meaning of hope, the enduring power of love, and the incredible resilience of the human spirit. And as I looked at Emily, her eyes shining with a newfound appreciation for life, I knew that our love story, though interrupted, was far from over. We would face the future together, stronger than ever before, grateful for the second chance at the life we had almost lost.
