This viral math problem has generated an extraordinary amount of controversy because of an obscure yet perfectly valid point that you might not have heard of. Can you figure out what that highly contentious issue might be?
If you’re somewhat familiar with online math brainteasers like this one, it’s clear that this problem deals with what’s known as the “order of operations.” The acronym for remembering this is PEMDAS/BODMAS, which breaks down as follows:
Literally millions of people online have tried this math problem on various social media platforms, and it has sparked a massive debate over what the correct answer is. Despite how clearly the order of operations are understood in the community of mathematics, the debate has split netizens into two main camps, which we shall explore here.
So, go ahead and solve the viral math problem, shown below, for yourself before scrolling down to find out what all of the fuss is about. What answer did you get? And which of the two camps do you belong to?

Seems pretty straightforward, right? Well, it’s not quite as simple as you may have thought.
Following the order of operations, the first precedent to be dealt with is the parenthetical expression (9 + 3), which is (12).
Also, that is exactly how any calculator would interpret such an expression—using the same order of operations as mentioned.
Dating back to an earlier age, there is an obscure exception to the modern rules for the order of operations from 1917 that was once in use. According to this exception, parenthetical expressions that are implicitly multiplication, like 2(12), are not treated in the same way as 2 x 12 would be, as per the order of operations.

Thus, going by the old the rule from 1917…
The parenthetical expression 2(12) is not implicitly dealt with like multiplication and division, and instead takes precedent. So, 2(12) equals 24, and 48 ÷ 24 gives us our final answer: 2.
Depending on which rule is used, there are two completely different answers. Most modern schools teach the first method, the one that our calculators follow, but there are some people out there who continue to follow the ways of olden times.
Which camp do you belong to?

Here’s Another Controversial Math Problem–and People Are Getting Into Heated Arguments Over It
This math problem was originally created for 5-year-olds in China. It might seem simple enough at first; however, a fierce debate ensued when the question first appeared online—and that’s what makes it so interesting.First, see if you can figure out the answer for yourself, and then we’ll dig into what all the clamor is about.
Note that there are pictorial differences between the flowers; the 2 yellow flowers in the third row are not equal to the single yellow flower in the last row. Also note that the number of blue petals on each of the blue flowers are not all the same.
Solve the problem in the illustration below:
Do not scroll down right away! Take a moment or two to come up with the solution, and then, when you’re ready (or if you’re completely stumped), check down below to see the answer and find out which side of the debate you ended up siding with.
Now here’s an explanation of how this was arrived at, as well as what all the the trivia surrounding this problem was about:
Arguably, the value of the 4-petaled flower remains unknown without any more information to tell us that, meaning that the solution is unsolvable.
This answer appears to be what the problem’s creators had in mind whether we like it or not!
This solution can be considered problematic if you wish to get finicky. For example, the blue flower also has a stem, a leaf, and a center, all of which arguably could be assigned a value that is impossible to determine.
What answer did you get, and what do you think of the debate surrounding this whole controversy?
