As many people in the United States are spending unprecedented time at home during this pandemic crisis, it’s easy to feel overwhelmed by the situation. But if the situation is getting you down, did you know that math just might be able to help?
Today, we'll give you a deceptively difficult math problem that will warm your brain up and then tell you how doing more math could help fight the symptoms of depression and anxiety.
A boost for your mind and your mood.
This math problem is multiple choice, so that should make it easier. Give this problem a try:
The problem looks easy enough, but not so fast; it’s not as simple as it looks. So take a moment and check your work, and when you think you have the correct answer, or if you’re completely stumped, scroll down below to see the solution.
If you just solve from left to right, you would start with 5 + 4, which equals 9. Then all that’s left is 9 × 2, which gives us a final answer of 18. The only problem is that 18 isn’t the correct answer.
Congratulations if you got this problem correct. However, if you were unable to answer this, you may be asking, “Why is that?” As we said, it’s not as simple as it seems!
You might recall from junior high math class a rule that applies to all math problems called the “order of operations.” Basically, that tells us which part of a math problem we must solve first, and the reason for this rule is that you can get different answers depending on the order in which it is solved. So, in order for everyone to be on the same page, there needs to be a common understanding, a common rule, which lets us know what order to solve the problem.
It’s also important to remember that when dealing with signs of the same order (for example: multiplication and division) they should be solved from left to right.
Keeping this in mind, let’s review the problem again:
5 + 4 × 2 = ?
5 + 8 = 13
The correct answer is 13!
The experimenters believe that the skills developed in doing mental math might help when you’re confronted by feelings of anger or distress. In these times, that’s definitely a useful thing. Scult suggests that doing math can literally help change the way you see the world and your own feelings.
“We don’t know for sure why that is, but it fit into our hypothesis that the ability to do these more complex math problems might allow you to more readily learn how to think about complex emotional situations in different ways,” Scult says. So keep calm, and calculate away.
