A Math Puzzle That Went Viral
An intriguing math puzzle recently shared on Facebook has challenged internet users to solve it without a calculator. Many of us have always viewed mathematics as a difficult subject in school, often associated with sighs of frustration or an immediate reach for the calculator.
However, when math takes the form of logical or reflective games, it can become fun and engaging.
If you enjoy stimulating your mind and taking on challenges, this puzzle is just for you.
The Challenge Shared on Social Media
This puzzle made its rounds on the internet after being shared by a Facebook account. The post presented the following challenge:
“Solve this math problem without a calculator:
40 + 40 – 70 x 0 + 20 + 10 = ?”
All accompanied by a playful warning: “No cheating.”
Another Riddle in the Same Spirit
This isn’t the first time such a challenge has gone viral. A previous puzzle had already confused many internet users.
Framed as a riddle for “geniuses,” it posed the question:
“If 2 = 6, 3 = 12, 4 = 20, 5 = 30, 6 = 42, then 9 = ?
Failure: 98%”
This type of riddle forces you to think outside the box and rely more on logic than simple calculations.
So, will you succeed in solving these riddles?
Why Do These Riddles Attract So Much Interest?
The popularity of math puzzles continues to rise. One reason for this is their ability to engage both children and adults.
These enigmas require logic, observation, and sometimes a bit of intuition. They also bring back memories of school for some, but this time with a playful twist.
Moreover, the challenge of not using tools like calculators enhances the game-like and competitive feel.
These puzzles not only entertain but also encourage online discussions: everyone shares their answers, defends their reasoning, and interacts with others in a friendly atmosphere.
Here Is The Answer We Found:
The equation is:
40 + 40 – 70 x 0 + 20 + 10
We must follow the order of operations, often recalled by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
Multiplication First:
The order of operations tells us to begin with multiplication, so we calculate:
70 x 0 = 0
Which simplifies to:
40 + 40 – 0 + 20 + 10
Addition and Subtraction (from left to right):
Next, we perform the additions and subtractions in the order they appear from left to right:
40 + 40 = 80
80 – 0 = 80
80 + 20 = 100
100 + 10 = 110
Final Answer:
40 + 40 – 70 x 0 + 20 + 10 = 110
Thus, the answer to the riddle is 110.
