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!

“Embarrassing,” Meghan Markle’s Latest Appearance Sparks Controversy as People Deem Her Dress “Too Revealing”
Meghan Markle’s surprise appearance at the Children’s Hospital Los Angeles Gala created quite a buzz, with reactions ranging from praise to criticism. Dressed in a bold red gown, the Duchess of Sussex turned heads, but her choice of attire sparked debate. While many commended her for supporting a charitable cause, others argued that the outfit was “unsuitable” for the event.
Meghan made an unexpected entrance at the annual Children’s Hospital Los Angeles Gala, catching everyone by surprise. The gala, which draws high-profile attendees to support pediatric healthcare, became even more talked about when Meghan arrived unannounced. Wearing a bold red halter-neck gown, she instantly captivated the room and turned heads with her striking presence.
Meghan’s outfit quickly stole the spotlight, though reactions weren’t solely about the fashion. While many fans praised her bold choice and admired her confidence, fashion critics were divided. Some viewed the striking gown as a powerful style statement, embodying her signature blend of elegance and modernity.
One critic remarked, “I wonder if she looks at herself in the mirror before she goes out? That dress just doesn’t look good on her!” Another added, “Yes, what a appropriate dress for a children’s function.” Additional comments included, “This is what you wear to a Children’s Hospital?” and “What’s she’s wearing for children’s event? Embarrassing…”
This is not the first time Meghan Markle has faced criticism for wearing inappropriate and overly revealing outfits. Recently, Meghan and Prince Harry visited Nigeria as part of the Invictus Games Anniversary celebrations. During this visit, Meghan’s choice of attire once again sparked controversy. Many deemed her dresses “revealing” and considered them inappropriate for the occasion.
Meghan also faced backlash for referring to Nigeria as “her country” after revealing she is 43% Nigerian. Critics pointed out the stark contrast between the Duchess’s lavish spending on attire and accessories and the country’s poverty, where over 112 million people live below the poverty line. This further fueled the controversy surrounding her visit.
Indeed, fans of the royal family often have plenty to say about Meghan’s looks. During her latest tour, people shared controversial comments regarding her choice of dresses. “I thought she hired a stylist? Inappropriate dress where the culture is modesty and especially to meet school children,” remarked one individual.
Meanwhile, Nicole Kidman also recently captured attention with her bold red carpet appearance, donning a daring dress that accentuated her cleavage. Some critics contended that the 57-year-old actress might be “too old” for such revealing outfits.
