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:
- Ignoring the Order of Operations (PEMDAS/BODMAS) – Many people solve the problem from left to right without following the correct order of operations.
- Misplacing Parentheses (Even When They Aren’t Written) – Some assume parentheses where there are none, changing how they approach division and subtraction.
- 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.

Think about it this way: If a recipe tells you to bake a cake at 350°F for 30 minutes before adding frosting, you wouldn’t reverse the steps, right? Math works the same way—sequence matters!

The Heartbreaking Last Photo of Kris Kristofferson That’s Shaking the Internet
Kris Kristofferson’s death marks the end of a special time. He wasn’t just a talented songwriter and musician, but also a poet who shared the deep feelings of life — love, loss, and everything in between.
His strong words and heartfelt voice touched many people.
Now, it’s his final photo that has left fans crying.
The news of Kris Kristofferson’s death has been hard, leaving a big gap in my heart.
For those who grew up with his music, it feels like we’ve lost someone irreplaceable. Now, with Willie Nelson being the last living member of The Highwaymen, we’re reminded that an important era of American music and culture is fading away.
But Kristofferson’s life was about more than just his time with that legendary group. Born with roots in Texas and Sweden, his career took off in the 1960s. He wrote timeless songs like “Sunday Mornin’ Comin’ Down,” “Help Me Make It Through the Night,” and “For the Good Times.” His lyrics weren’t just songs — they were like poetry, capturing the raw feelings of life.
Most people would need many lifetimes to do what Kris did in one. He wasn’t just an award-winning musician — he also acted in movies, starring with Barbra Streisand in *A Star Is Born* (1976), a role that won him a Golden Globe.
“He was something special.”
“The first time I saw Kris performing at the Troubadour club in L.A., I knew he was special,” his co-star Streisand shared on Instagram. “Barefoot, playing his guitar, he seemed perfect for the movie I was working on, which became *A Star Is Born*.”
Kristofferson was also an Army ranger, a Rhodes scholar, a helicopter pilot, and, most importantly, a storyteller. His work touched many generations. As country singer Channing Wilson wrote on Instagram, “Kris, you left this world better than you found it.”
Beyond his music and movies, Kris had a huge heart. He fought for social justice, supporting civil rights and gender equality. Even as he got older, he stayed active, helping raise awareness and funds for groups like the United Farm Workers (UFW).
Last Instagram photo
Kris passed away peacefully at his home in Maui, Hawaii, on September 28. No cause of death was shared.
His Instagram was soon filled with tributes, as fans posted memories of how his music changed their lives. But it was his last public photo, shared by country star Tanya Tucker in April, that really touched people’s hearts.
In the photo, Kris stands next to Tanya, both representing the golden age of country music. Kris is wearing a Muhammad Ali T-shirt and smiling softly. Though age has softened his rugged looks, his spirit still shines. The young, bearded heartthrob may be gone, but what remains is a legend — a man whose presence is unmistakable, even in his later years.
