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!

Taylor Swift Faces Backlash for ‘Street Walker’ Style at the Game—See the Controversial Outfit!
Taylor Swift is famous for her daring fashion choices. However, her recent look at a Kansas City Chiefs game received a lot of criticism from people online.
The main issue was her outfit, which featured a large red Kansas City Chiefs t-shirt that she turned into a loose mini dress. In classic Swift style, she matched this with thigh-high black leather boots, a black crossbody bag, and several gold chains.
She finished her look with hoop earrings and her signature bold red lipstick, while her blonde hair flowed in messy waves. Swift made a strong fashion statement as she arrived and later cheered from the Chiefs’ VIP suite.
Fans are used to seeing her push the limits of fashion, but her outfit for the game didn’t please everyone. Many comments appeared on social media, with one user asking, “With all her money, that’s what she wears?”
Critics also noted that her outfit felt mismatched compared to the wives and girlfriends of other players, who wore more typical game-day outfits. One commenter remarked, “She dresses like a teenager.”
Viewership of Kelce’s games has increased, with fans and commentators saying that Swift’s celebrity influence has brought more attention to an already popular sport.
Some people wondered if her recent fashion changes are part of a bigger publicity plan since her relationship with Travis Kelce became known. One user commented, “Her outfits are getting goofier. Does she really need the attention? It seems like since being with Kelce, she’s all about PR.”
Since Swift’s rumored relationship with Kansas City Chiefs star Kelce became public, the attention surrounding his games has skyrocketed. Known for her ability to influence culture, Swift has added a new level of excitement to the NFL, especially for the Chiefs.
Viewership of Kelce’s games has increased significantly, with fans and commentators crediting Swift’s star power for drawing more attention to an already popular sport. It’s no surprise that her influence extends to everything she engages with, from music to football.
Despite his impressive career, Kelce’s increased attention isn’t just because of his skills on the field. Much of it comes from Swift being in the stands. With this heightened spotlight, both Kelce and Swift are facing more scrutiny than ever.
