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!

Riona was cruelly set on fire — after a year of recovery, she’s finally going to her new home
The degree of cruelty some humans have towards dogs is simply unfathomable. Riona, a cute puppy, endured the most agony of all when her owner cruelly burned her on fire the previous year.
But Riona is finally moving to her new house, almost precisely a year after that terrible event.
Residents of Nutbush, Tennessee saw the horrifying sight last June when Riona, a pitbull mix, ran down the street while completely engulfed in flames. It was obvious from the gas scent that she had been purposefully set ablaze.
The degree of cruelty some humans have towards dogs is simply unfathomable. Riona, a cute puppy, endured the most agony of all when her owner cruelly burned her on fire the previous year.
But Riona is finally moving to her new house, almost precisely a year after that terrible event.
Residents of Nutbush, Tennessee saw the horrifying sight last June when Riona, a pitbull mix, ran down the street while completely engulfed in flames. It was obvious from the gas scent that she had been purposefully set ablaze.
Riona’s tale was told in a TikTok video that went viral and received millions of views, inspiring compassion for Riona all around the world.
Riona’s journey to recovery was lengthy, requiring multiple skin grafts to address the fourth-degree burns that covered her entire body. Riona was claimed to have been frightened by the experience, yet she was also upbeat during her recuperation.
Mclemore remarked, “She’s just always wagging her tail.”I suppose that’s what makes it even worse. Just being so lovely, and for someone to do something like this to her—not that it would ever be OK. She simply adores everyone.
The Commercial Appeal was informed by Natoli that “she’s actually kind of cute with one ear.”It adds cuteness to her personality.
Supporters brought presents and donations for Riona, and Tails of Hope kept posting updates on her progress.
Quishon Brown, 43, was taken into custody in the meanwhile for allegedly setting Riona on fire. He was accused by the police of misdemeanor assault, two felonies, severe animal cruelty, and setting fire to personal property. Trial in the case is presently pending.
A Facebook post claims that Riona’s story contributed to the passage of a new Tennessee law against animal abuse.
Riona’s condition gradually got better over the course of several months. Riona’s story has lately had an encouraging development: nearly precisely a year after she was set on fire, she is finally moving to her new home!
Riona would be traveling for 10 hours to reach her new permanent home, according to a post made by Tails of Hope.
“We wanted to find her a forever home, and we succeeded in doing so,” Natoli stated to the Commercial Appeal. “Riona has a large yard to play in, children to play with, other dogs to play with, and a family that understands what her injuries were and has experience in the medical field.”
The rescue posted on Facebook, saying, “Riona’s story is not coming to an end, in fact it is really just beginning.” “Our ‘warrior’ girl, we have all shared in this miracle together.”
Tails of Hope added that just after Riona departed for her new home, they took in another rescue dog who had suffered burns, serving as a reminder of how important animal rescue work is never done. They wrote, “There is always someone else in need.” We get to participate in yet another story right now.
What a terrible ordeal for this beautiful, kind dog to go through, but we’re overjoyed that Riona is moving on to her new home after a year!
