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!

62-year-old Billy Ray Cyrus marries 34-year-old bride Firerose – fans upset by one little detail
Billy Ray Cyrus recently celebrated his wedding to Firerose in an intimate ceremony. This union followed his divorce from Tish Cyrus in 2022, marking the third time they filed for divorce after 28 years of marriage. Following the divorce, Billy Ray Cyrus began dating Firerose, an Australian artist, and the two announced their engagement in November 2022.
Interestingly, Billy Ray and Firerose had crossed paths years ago when Firerose auditioned for a role on “Hannah Montana” 13 years prior. This serendipitous encounter left a lasting impression on Billy Ray, who recalled the moment he first saw her and sensed her star potential. Although she didn’t land the role, Billy Ray introduced her to some producers, which ultimately led to a friendship that would later blossom into a romantic relationship.
Billy Ray and Firerose’s love story developed after his divorce in early 2022. They officially became a couple, and Firerose moved in with him in August 2022. Shortly thereafter, he proposed, and they decided to make their love official through marriage.
Their wedding coincided with Tish Cyrus, Billy Ray’s ex-wife, remarrying in August 2023 to “Prison Break” star Dominic Purcell. Tish’s two children from a previous relationship, Brandi and Trace, were in attendance at her wedding. Billy Ray had adopted Brandi and Trace while he was married to Tish. Billy Ray and Tish also have three children together: Miley Cyrus, Braison, and Noah.
Notably, Noah and Braison were absent from their mother’s wedding. They were seen together on the day of the wedding, posting on Instagram about their outing to Walmart. The choice of their outing on the wedding day raised some eyebrows.
As Billy Ray and Firerose shared pictures from their wedding day on social media, some fans focused on one detail: Billy Ray Cyrus’s hair. Some fans expressed surprise and wondered why he didn’t style his hair differently for the occasion, with comments like, “Could have at least brushed his hair for the occasion” and “He couldn’t comb his hair??” This sparked discussion about his hairstyle choice for the wedding.
Billy Ray Cyrus and Firerose’s wedding marked a significant moment in their relationship, and while the focus may have been on his hair for some, it’s a celebration of love and happiness that they both clearly cherish.
