We all know how important it is to work out regularly if you want to live a long and happy life.

But what many people tend to forget, is that keeping your brain in shape is just as important, especially after becoming a bit older.

There are, of course, lots of ways to keep the brain flexible and healthy, Crosswords and Sudoku are great mind-teasers for example.

But lately, a completely different type of challenge has re-emerged on the Internet – old fashioned school math!

Challenging yourself every now and then is good for your health – and it always feels like your mind is much clearer afterward.

Of course, you exercise your brain at work as well, but while solving puzzles you use it differently.

Testing how much you remember from school math is an excellent way to stimulate your brain.

## Can you solve this math test?

Okay, here comes the task.

Below is a picture with five numbers in succession.

All the digits have a connection. Your task is to figure what that connection is.

Here’s the picture – can you solve this math test?

Do you see the connection? Look carefully at each figure and think about it.

Did you figure it out?

If not, the answer will appear after the picture below.

## Time for the answer

The answer is: all numbers will total 7 if you add both of their digits together.

So here: 4 + 3 = 7, 6 + 1 = 7, 2 + 5 = 7, 3 + 4 = 7, and 1 + 6 = 6.
