Why do these problems go Viral on the Internet?
Although many problems are tricky and require much effort, these viral math questions look simple. At first sight, everyone thinks they can solve it within a few seconds. But when they try and see the solution and approach other people to solve it, this problem becomes complicated.
Here are the top 3 reasons this simple math problem has gone viral on Social Media and YouTube.
- The problem has two different solutions, and both are correct.
- Different types of the hierarchy of operations interpret two other solutions.
- Teachers marking on a math quiz make conflict and firestorms on Reddit.
Top 10 Viral math Problems and Their Step-by-Step Solutions
Problem 1: Viral Math Problem on Youtube
This problem has gone viral on YouTube due to two versions of the order of operations. There needs to be more clarity in which the multiplication sign is omitted. There are two different ways to approach this.
METHOD 1: BY PEMDAS RULE
| P | Parenthesis |
| E | Exponents |
| M | Multiplication |
| D | Division |
| A | Addition |
Now, according to PEMDAS rule, multiplication comes first, then divisions.
$$6\div2(1+2)$$
$$=6\div2\times3$$
$$=6\times6$$
In PEDMAS, multiplications come first.
$$=1$$
METHOD 2: BY BODMAS RULE
| B | Brackets |
| O | Order |
| D | Division |
| M | Multiplication |
| A | Addition |
| S | Subtraction |
Now, according to PEMDAS rule, multiplication comes first, then divisions.
$$6\div2(1+2)$$
$$=6\div2\times3$$
$$=3\times3$$
In the BODMAS rule, first we divide and then multiply.
$$=9$$
Problem 2
In 2016, a test revealed that, compared to 90% in the 1980s, just 60% of Japanese 20-year-olds could answer this equation. Once more, the order of operations is the cause of the issue.
METHOD 1: BY PEMDAS RULE
| P | Parenthesis |
| E | Exponents |
| M | Multiplication |
| D | Division |
| A | Addition |
| S | Subtraction |
Now, according to PEMDAS rule, multiplication comes first, then divisions.
$$9-3\div1/3+1$$
$$=6\div2\times3$$
$$=3\times3$$
$$=9$$
METHOD 2: BY BODMAS RULE
| B | Brackets |
| O | Order |
| D | Division |
| M | Multiplication |
| A | Addition |
| S | Subtraction |
$$9-3\div1/3+1$$
$$=9-9+1$$
$$=1$$
In the BODMAS rule, first we divide and then multiply.
Problem 3
The volume of a cylinder = π × radius² × height.
- Therefore, the volume of the cylinder = π × 4² × 10 cm = 160π cm³.
Problem 4
METHOD 1: BY PEMDAS RULE
In the PEMDAS rule, first we multiply and then divide.
$$6^2\div2(3)+4$$
$$=36\div6+4$$
$$=6+4$$
$$=10$$
METHOD 2: BY BODMAS RULE
In the BODMAS rule, first we divide and then multiply.
$$6^2\div2(3)+4$$
$$=18\times3+4$$
$$=54+4$$
$$=58$$
Problem 5: Viral Math Problem: 50% of people give the wrong answer.
The equation representing the total cost of the bat and ball is:
$$x = 0.05$$
Therefore, the ball costs 0.05 dollars or 5 cents.
Problem 6: Trending Math Problems on Facebook:
Every math problem has a unique solution. But in 2023, a few problems go viral on the internet that has two different solutions and both seem to be correct.
Method 1: Adding the Previous Number
$$1+4=5$$
Now add the 5 and the next two digits.
$$5+2+5=12$$
Now add 12 and the next two digits.
$$12+3+6=21$$
Similarly, adding 21 and other numbers 8 and 11.
$$21+8+11=40$$
Method 2: Multiplying the number and adding the first number in it.
$$4+1=5$$
Now multiply 1 and 4 and then add 1.
$$5+2+5=12$$
Now add 12 and the next two digits.
$$3+6+3=21$$
Similarly, adding 21 and other numbers 8 and 11.
$$8+11+8=96$$
Problem 7
The solution to this problem requires logical reasoning and the use of a process of elimination. One needs to carefully consider the information provided in the problem and use it to eliminate the dates that are not possible. By asking specific questions to each other, Albert and Bernard can narrow down the possible dates until they have enough information to determine the birthday accurately.
Albert: I’m not sure of Cheryl’s birthday, but I’m certain that Bernard isn’t either.
Since every month includes more than one conceivable date, Albert only knows the month. It stands to reason that he is unaware of her birthday. The sentence’s first clause is unnecessary.
Bernard, however, would only have known the date with a single number if Cheryl had informed him 18 or 19, as these are the two numbers that appear only once in the ten date alternatives, as May 19 and June 18.
Albert must have been informed in July or August in order for him to be aware of Bernard’s ignorance, ruling out Bernard being informed at the age of 18 or 19.
Secondly, Bernard
I didn’t know Cheryl’s birthdate at first, but I do now.
Albert has either August or July, according to Bernard’s deduction. If he is aware of the entire date, he must have been informed when he was 15, 16, or 17, as if he had been informed when he was 14 he would not have known if the month was August or July. Only one exact month is mentioned in each of 15, 16, and 17, although 14 might be either month.
Line 3 Albert: Consequently, I am aware of Cheryl’s birthday.
Albert has consequently determined that July 16, August 15, and August 17 are potential dates. He had to have been informed in July for him to know now. If August had been the month mentioned, he would not be positive of the birthday’s exact day.
The answer is, therefore, July 16.
Problem 8: Viral Math Problem on Twitter
Method 1 by BODMAS:
In the BODMAS rule, first we divide and then multiply.
$$8\div2(2+2)$$
$$=8\div2\times4$$
$$=4\times4$$
$$=16$$
Method 2 by PEMDAS:
Now, according to Pemdas rule, multiplication comes first, then divisions.
$$8\div2(2+2)$$
$$=8\div2\times4$$
$$=8\div8$$
$$=1$$
Problem 9 :Trending Math Problems on Reddit:
This standard core math quiz goes viral due to an appropriate marking. Here the teacher asked students to solve the 53 with repeated addition. Students attempt it by writing 5+5+5,,,which is the correct way. But the teacher crosses it and writes the answer by adding three five times.
Both approaches to the problem are right, but teachers’ grading makes this math quiz viral. So, checking such issues also gives value to the student approach if it is correct.
PROBLEM 10: Trending Math Problem On Quora:
Nothing is lacking; everything is wonderful. Just the calculation is off.
You gave your parents $2 back, but in reality you borrowed and spent $98. You are adding the debt ($98) and your savings ($1) in the question, but you are forgetting that your savings ($1) come from your debt ($98). [For example, debt amount of $98 = bag-$97 + your savings-$1]
A CLEAR IMAGE
Before making the purchase, you had $100 (which you lent your parents $50 plus $50).
And after payment, you have: $97 (for the bag) plus $3 (for change).
After giving $1 back to Mom and Dad, you have: $97 (bag) + $1 (savings).
Finally,
$100 = $97 for the bag, $1 for your savings, and $2 for the money you gave your parents.
Conclusion: After the purchase, you have $97 + $1 = $98 and your parents have $2. Before the purchase, you had $100.

Final Verdicts:
The math solution remains the same throughout the word. But all the above math problems go viral online due to their two answers. All this confusion and mess was created because of an inappropriate way of writing the problem. We will get one unique answer if all the problems are deemed properly.
If you want to increase your kids’ math skills, give them different math games.
Conclusion
In conclusion, geometric shapes are an essential mathematics topic with many real-life applications. Understanding the properties of geometric shapes is necessary in various fields, including architecture, engineering, physics, and art. 2D shapes are flat and have only two dimensions, while 3D shapes are solid and have three dimensions.
Both shapes have unique properties that make them useful in different applications. By understanding the basics of geometric shapes, we can appreciate their beauty and usefulness daily.
