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!

Bill Belichick Started Dating 24-Year-Old Cheerleader Jordon Hudson Over a Year Ago
It has been claimed for more than a year that former Patriots head coach Bill Belichick, who has witnessed more football seasons than most of us have seen on tax returns, has been dating 24-year-old cheerleader Jordon Hudson. Indeed, if you quickly calculated, Belichick is 72 years old. Surely, age is just a number?
PEOPLE has revealed that Belichick and Hudson have been dating for a while, which supports our suspicions. During numerous public appearances, Hudson—a former cheerleader at Bridgewater State University—has drawn attention in addition to the former NFL coach.
The gossip site TMZ originally revealed this tasty detail, in case you were under the impression that it was simply a rumor. As we all know, TMZ never exaggerates. Belichick’s former players, Rob Gronkowski and Tom Brady, were aware of the age gap and brought out the marshmallow roast during Netflix’s live special, The Greatest Roast of All Time: Tom Brady.
“Coach, you used to talk about Foxborough High School when we sucked,” Gronkowski said, unable to contain his annoyance. However, I now see why you were so fascinated with Foxborough High School: you were scoping out potential girlfriend material. Gronk, ouch! That one is intelligent.
Not one to pass on the opportunity to poke fun at his former coach, Brady continued, “I used to say ‘the next one,’ when someone asked which ring was my favorite.” “That Ring camera that captured Coach Belichick sneaking out of that poor girl’s house at six in the morning a few months ago is my favorite now that I’m retired.” Brady was a savage. Absolute barbarism.
Let’s go back a little, though. Linda Holliday, Belichick’s 16-year girlfriend, came before Hudson. A PEOPLE source claims that their long-term relationship ended in September 2023. You ask, what went wrong? According to the sources, these were long-simmering difficulties rather than anything brand-new.
Holliday held the position of president of Belichick’s Bill Belichick Foundation and has been associated with him since 2007. The insider claimed, “They have issues to resolve that stem from a long relationship as well as her role in his professional life.” The juggling act between coaching responsibilities and personal life is unimaginable.
