Can you solve this simple math puzzle?<\/p>\n
Take a close look at the note on the desk.<\/p>\n
It says: 70 \u00f7 1\/7 \u00d7 7 = ?<\/p>\n
At first glance, it looks like elementary school math.<\/p>\n
You probably feel like you can solve it in two seconds.<\/p>\n
Many people glance at it and immediately say the answer is 70.<\/p>\n
They might think: 70 divided by something times 7 just cancels out.<\/p>\n
Or perhaps they quickly calculate 1\/7 \u00d7 7 = 1, and then 70 \u00f7 1 = 70.<\/p>\n
It sounds very logical, right?<\/p>\n
Well, that is exactly why the note says: Answer is not 70!<\/p>\n
If 70 is wrong, what is the real answer?<\/p>\n
More importantly, why do so many smart adults get this wrong?<\/p>\n
Let us break it down step by step using basic math rules.<\/p>\n
Do you remember the order of operations from school?<\/p>\n
Many of us learned PEMDAS or BODMAS.<\/p>\n
These rules teach us how to read a math sentence properly.<\/p>\n
First, we do parentheses and brackets.<\/p>\n
Next come exponents and roots.<\/p>\n
Then comes multiplication and division.<\/p>\n
Finally, we do addition and subtraction.<\/p>\n
Here is the key detail that catches most people off guard:<\/p>\n
Multiplication does not automatically come before division.<\/p>\n
They actually have the exact same priority level.<\/p>\n
When a problem has only multiplication and division, there is one golden rule:<\/p>\n
You must solve from left to right!<\/p>\n
Just like reading a book, you start on the far left.<\/p>\n
Let us look back at our equation: 70 \u00f7 1\/7 \u00d7 7.<\/p>\n
Following the rule, the first operation on the left is 70 \u00f7 1\/7.<\/p>\n
How do we divide a whole number by a fraction?<\/p>\n
Do you remember the \u201cflip and multiply\u201d rule?<\/p>\n
To divide by a fraction, you multiply by its reciprocal.<\/p>\n
The reciprocal of 1\/7 is simply 7\/1, which equals 7.<\/p>\n
So, dividing 70 by 1\/7 is the exact same thing as multiplying 70 by 7!<\/p>\n
Let us calculate that first step:<\/p>\n
70 \u00d7 7 = 490.<\/p>\n
Think about it in real life.<\/p>\n
Imagine you have 70 whole pizzas.<\/p>\n
If you cut every single pizza into 7 equal slices, how many slices do you have?<\/p>\n
You do not end up with 10 slices; you end up with 490 slices!<\/p>\n
Dividing by a fraction makes your number bigger, not smaller.<\/p>\n
Now, we have finished the first part of our expression.<\/p>\n
We are left with the final step from left to right:<\/p>\n
Take that 490 and multiply it by the last 7.<\/p>\n
Let us do the multiplication:<\/p>\n
490 \u00d7 7 = 3430.<\/p>\n
And that is the whole secret!<\/p>\n
The mathematically correct answer is 3430.<\/strong><\/p>\n It is not 70, and it is not 10.<\/p>\n Math is wonderful because simple rules never change.<\/p>\n Did you get 3430 on your first try?<\/p>\n Share this with your friends and see how many of them fall into the trap!<\/p>\n","protected":false},"excerpt":{"rendered":" Can you solve this simple math puzzle?
