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!

“Age Isn’t a Deal-Breaker for Me,” a 46-Year-Old Mom Reveals Her Views on Relationships With Younger Men
Many people invest significant time and effort in the quest for eternal youth. This pursuit has now become a major inspiration for numerous cosmetic companies, beauty care brands, and even plastic surgeons. However, amid this quest are those like Joleen Diaz, a 46-year-old mother who bears an uncanny resemblance to her own daughter.
Joleen has a 23-year-old daughter.
Joleen Diaz, aged 46, and her 23-year-old daughter, Meilani Parks, took the internet by storm with astonishing Instagram photos. They appeared nearly identical while enjoying a day at the beach in their swimsuits.
Remarkably, despite a substantial 24-year age difference, these two California women are often mistaken for sisters. “While she was growing up, she often heard people tell me they thought my mother was my sister,” Joleen revealed. It appears this resemblance runs in the family.
Her youthful looks sometimes bring her trouble.
Joleen Diaz relocated to California at the age of 10, and she currently holds a position at an elementary school, teaching 3rd and 4th-grade students. In the past, she was married, and during this marriage, she became the mother of two children, Meilani Parks and Jordan. Joleen has lived as a single parent since parting ways with her husband.
Now, Joleen Diaz enjoys a notable presence on Instagram, and she frequently receives messages from younger men. Her remarkably youthful looks have led to instances where people reported her Hinge profile, suspecting it to be a fake account. “I’ve had my account deleted several times,” she said. “It’s funny, I think people think I’m a fake account and report me.”
According to Joleen, the internet has created a misleading image of her.
With over 600,000 Instagram followers, this stunning woman frequently shares her glamorous selfies and bikini snapshots. However, she wants people to see her true personality beyond these photos. She believes her social media doesn’t capture her simple, down-to-earth nature. She prefers to connect with someone first and then introduce them to her social media once they get to know her better because she wants to demonstrate that she’s not as glamorous as her online persona might make her seem.
Joleen is still waiting for love to enter her life.
Although younger men often show interest in Joleen on social media and dating apps, she prefers to leave the millennial guys for her daughter Meilani.
She clarified her stance by saying, “Age isn’t a deal-breaker for me, but I don’t want to date a toyboy. I would never even remotely consider dating someone who is young enough to be friends with my daughter.”
Joleen is in search of mature men who meet her criteria. She explained, “I gravitate toward ambitious, motivated men, someone who is confident, has a positive outlook, and can communicate well.” The mother-daughter duo intends to continue double dating until they both find their ideal partners.
They’re more than just mom and daughter.
Currently, the mother-daughter duo have profiles on several dating apps. They frequently engage in double dates and are interested in assessing each other’s potential partners.
Joleen explained, “When we see people, we often go bowling, to the movies, hikes, to the beach. Meilani asks for my advice on dating all the time. I love that she trusts in the advice I give. I feel like she’s well-balanced in dating, and I’m glad my experiences can help her out.”
Though there’s no definitive formula for retaining a youthful appearance indefinitely, some women have discovered effective practices that work for them, enabling them to preserve their beauty throughout the years.
