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!

Fans worried Miley Cyrus in “in danger” after spotting bodyguard’s hidden move at Grammy Awards
It was a big night for singer Miley Cyrus last night as she took home her first ever Grammy Award.
However, this morning it wasn’t just Miley’s success that was being talked about online, but also the worrying idea that she may have been in danger.
Why? Well, some eagle-eyed speculators online have suggested that they saw “odd behavior” from her bodyguard which might imply that he was anticipating a threat of some kind.
Now, we feel it necessary at this point to make it clear that there is no evidence that Cyrus was in any danger, beyond what people are claiming to have seen in a video doing the rounds online.
Nevertheless, said clip has garnered so much attention that it just won’t do to ignore it. So, here goes.
The video in question comes from the red carpet at the 2024 Grammy Awards, which took place last night (February 4) and saw a number of musicians – like, a lot of them – win awards for their work over the past year.
The evening saw Taylor Swift win her fourth Album of the Year award, and featured a surprise appearance from Celine Dion as a presenter. Miley Cyrus also won her first ever Grammy, but it’s arguably a video trending on X that has become the most talked about point of the night where the 31-year-old is concerned.
As mentioned, footage of Cyrus on the event’s red carpet has gone viral. The clip, which shows the Wrecking Ball singer walking beside her bodyguard, who is carrying an umbrella, is only eight seconds long, but has already wracked up a mind-boggling 32 million views.
At first glance there isn’t much of anything to spot in the video – anything out of the ordinary, in any case – but take one look at what people are saying on X and you’ll be brought up to speed.
“Fake arm holding umbrella. So arm is under coat presumably with a weapon. Completely unnecessary at the Grammy Awards. This bodyguard is a clown. But in serious environments the fake arm is a common tactic,” one person commented.
“Auto firearm dressed as an umbrella?” another speculated.
“Pay close attention to Miley Cyrus’s bodyguard in this video at the Grammys all is not as it seems,” a third wrote.
A fourth added: “Did you catch the mysterious moves of Miley Cyrus‘s bodyguard at the Grammys There’s more to the story than meets the eye!“
Naturally there were others who took a less suspicious approach to the whole thing.
“It’s an umbrella weapon to rain lol! Not a gun,” one X user wrote.
Another added: “Miley Cyrus’s bodyguard is either carrying a gun disguised as an umbrella or is wearing a fake arm to disguise his real arm, again for security reasons. Bla, bla, bla. People are going nuts. It was raining. It’s an umbrella.“
“Tha narrative of a fake arm sounds good but let’s be realistic, it’s Miley Cyrus at the Grammies. This isn’t some world leader and I’m literally staring at his live hand holding an umbrella. It’s his juts him walking like he’s on a runway,” a third said.
