# This is the math problem that hits TikTok and is making people cry

If numbers are not your strong suit, surely math has made you cry on more than one occasion. Even if you have already passed your student days and you think you can forget this dreaded subject forever, to this day the numbers can still bring you tears or tears.

This has been demonstrated **the latest math problem to go viral on TikTok**. The popular social network of short videos has shown that where we fail the most is in solving simple questions, and this has caused some people to end up crying when they verify their error.

But what is this controversial math problem? Far from having a complex statement, it is formulated in a very simple way: **Can 87 be divided, or is it a prime number?**

Before consulting the answer, first of all** think a bit and answer what you think is the correct solution**. It can’t take long to answer, so spend at most ten seconds and say what comes to mind.

If it is such a simple problem, why do many people have a hard time solving it? What happens is that the mind plays a trick on us. Although 87 may seem like a prime number a priori, it is actually a composite number: **It can be divided by 3, resulting in 29.**

Being an odd number and ending in 7 (one of the most well-known prime numbers to all), it makes many people think at first that 87 is a prime number.

As you can see in the video below these lines, the tears that this math problem is causing are actually an exaggerated humorous reaction to how simple the answer is.** And you, have you been right or have you also ended up making a sea of tears?**

If you have failed, so that the same thing does not happen to you next time we remind you that, to find out if a number is divisible by 3, you have to add all its figures. If the result is a multiple of 3, then it can be divided by 3.
