A woman on TikTok gave a group of engineers a maths riddle and it left them completely stumped. Watch below:
Karin Gendi gave her clever mates three minutes to figure out the 'equation'.

She handed them a piece of paper with two '100' numbers on top of one another, with a line underneath.
The TikToker asked them: "If you can turn this into two hundred with one line, I'll give you whatever you want."
At first the three friends looked at one another, as if to say - 'is this a joke?'.
However as one minute passed, they began to struggle with it.

One asked: "With one line?"
Where Karin responded: "Using only one line."
Another friend hilariously turned the page upside down and said: "let's look at this from another perspective."
However, just as the time was about to run out, one of her mates managed to crack the code.

By inserting a small line across the '1' of the first '100', the page then reads - 'too hundred'.
Don't worry it took me a while to get it as well.
The viral vid was posted six days ago (21 Sept) and racked up a mega 38.2 million views.

Users were, of course, quick to comment on the post.
One user wrote: "'Let's look at it from a different perspective' haha yep they've been in an engineering class before."
Another user suggested: "Change first 100 to Too.'
Whilst a third commented: "Lol. He got it.

"You could see the light bulb go off."
A final user concluded: "Suddenly the room went quiet when she brought out the puzzle, true engineers."
