In this equation, a math Ph.D. has a very different opinion from an ordinary person. Who’s side are you on? Who is right and who is wrong? Let’s settle it!
Ready for the viral equation?
Okay, get ready. We hope you manage to solve it. Try your very, very best not to peek at the answer that follows. Give it your best shot at working it out first, okay? Here goes!
The viral equation goes like this: 230 – 22 ÷ 2 =
But, what makes this equation even more confusing is the answer of the Math Ph.D. who says the answer is 5. But, the majority of people are coming to the answer of 120. Who is right? Who is wrong? Can you figure it out?
Ready for the answer?
So, as it turns out, this viral equation has TWO possible answers. Yup! However, it depends on how you worked it out. The correct answer is in fact, 120 and not 5. How can that be? Let us have a look at why, and the two ways of working out this problem. Here is the first:
And, here is the wrong way:
