It’s time to dust off the old number two pencil and grab an eraser, because this easy math problem has stumped a lot of people.
Can you solve it in under 30 seconds?
The equation, shared by @BholanathDutta on X, is 75+25÷5×5.
Ready for your timed test?
But first, here’s a hint: Ever heard of PEMDAS?
The age-old acronym guides you through the proper order for solving a complicated calculation like this one.
It stands for Parentheses, Exponents, Multiplication, Division, Addition, and then Subtraction.
Now, off you go!

Did you get it?
The answer is 100.
So how do you get there?
First, you start with division. So 25÷5=5.
Then you have to multiply by 5, equaling 25.
Lastly, you have to add the 75, bringing the total to 100.
Some people in the comments stumbled and got 76 by doing the multiplication first (5×5=25) and then dividing it by 25, totaling 1. Then adding 75 brings it to 76.
However, this method is wrong because the multiplication and division go in the order they appear in the equation, according to the rules of PEMDAS.

Multiplication does not have to done first just because it’s in the acronym before division.
Others got 4 by doing the addition – which comes second to last in PEMDAS – first. 75+25=100. The taking 5×5=25. And taking the 100÷25=4.
However, being that there are no parentheses or exponents and multiplication and division come in the order they are in the equation, you have to start with division, then multiply, then add.
