Hey friends, welcome back to our daily brain teaser challenge!
Today, we have a quick math puzzle printed on a piece of paper that looks super simple at first glance.
In fact, it even warns you right at the top: “The answer is NOT 65!”
So, why do so many people fall into the exact same trap and end up getting 65 anyway?
Let’s break down the problem together step by step to see where the trick lies.
The puzzle reads: “93 minus 13 divided by half plus 4 is?”
Most people read this from left to right and make a classic math mistake.
They do 93 minus 13 first, which gives 80.
Then they divide 80 by 2 to get 40, and finally add 4 to get 44—or they divide by 2 incorrectly in another order to get 65.
However, basic math rules like order of operations (PEMDAS) and basic fractions change everything.
First, “divided by half” does NOT mean dividing by 2!
It means dividing by the fraction 1/2 (or 0.5).
When you divide any number by a half, you are actually multiplying that number by 2.
Second, according to the order of operations, we must do division before subtraction and addition.
So, we start with the division part: 13 divided by 1/2
13 ÷ 0.5 = 26
Now, let’s plug 26 back into our full expression.
Our equation now looks like this: 93 minus 26 plus 4.
Next, we just work from left to right with addition and subtraction.
93 – 26 = 67
Finally, we add 4 to 67: 67 + 4 = 71
And there you have it!
The correct answer to this viral puzzle is actually 71!
Did you get it right on your first try, or did the tricky wording catch you off guard?
