Each year that passes by, memories from school feel further and further away. What you learned then is difficult to remember, especially math. With a hand on your heart, how many times have you used Pythagoras’ theorem since you finished school?
We live in uncertain times, to stop the coronavirus outbreak, we need to stay inside, isolated from friends, family and even coworkers. Social interaction has become something you do over Facetime or Google Hangouts.
It’s easy to worry and stress over what will happen. However, remember that as long as you are doing your part, it’s out of your (washed) hands. Here at The Laugh Club, we try to help you take your mind off things and maybe heal it a bit through some light exercise.
With that said, old school math problems can be a great way to keep our brains healthy – trust me, it’ll feel great to finally give your brain a light workout!
It is also a good way to keep a sharp mind and a fresh mentality, something we need now more than ever. Besides, it’s always fun to challenge your competition instinct!
There are, of course, plenty of different ways to do it, especially now thanks to the internet.
The old classics, crosswords and sudoku, have been in the newspapers for generations. Lately, however, an even older type of brainteaser has re-emerged online.
Good ‘ol school problems

Some of these challenges go back all the way to school, however, they become quite difficult considering how much time has passed since you last went there.
How many triangles?
Here comes the problem. It’s not math, but I remember this particular challenge in our geometry class.
Below, in the image – how many triangles are there?
How many triangles can you find? The answer is after the picture below.
There are quite a few
It is important to think a little outside the so-famous box to figure this one out.
The correct answer is 13 triangles, that is, alternative C. Don’t worry, we’ll explain.
First, we have nine small triangles.
Then we have three slightly larger triangles made of four small ones.
Finally, we have a big one made out of all the triangles inside.
9 + 3 + 1 = 13.
