The image below is made up by these 4 different things as you can see. The answer consists of 5 characters.

What does it represent?

enter image description here

Hint(related to image 1)

A number, a triangle, a polygon

Hint2(related to one of the remaining 3 images)

D, I, L etc...

Hint3(related to image 4)

A letter and a number

Hint4(related to image 1 again, since this one probably is the hardest one)

grey(nr), yellow, yellow

  • $\begingroup$ No, its a completely different answer! $\endgroup$ Mar 20, 2020 at 16:41

  • $\begingroup$ I think I've figured out the first two characters (first two images), maybe, but still stuck on the second half. $\endgroup$ Mar 22, 2020 at 11:59
  • $\begingroup$ Maybe you have. Also, keep in mind that only one of the 4 images represent two characters(since the answer is 5 characters)! $\endgroup$ Mar 23, 2020 at 4:54

With a tip of the hat to Rand, the answer is:

E=mc2 (that's a squared)

I interpret the pictures as follows:


E (The three objects are '14' and a triangle 'base' and '16' vertices. 14 in base 16 is 'E'.)


= (as Rand noted, a set of scales indicating an 'equal' reading).


M (the output of the function Roman(1000))


c squared (a picture of the 'sea' placed within a square, thereby being 'squared')

  • $\begingroup$ Darn, good job. I'd thought this was probably going to be the answer, but then I had to do some other things before coming back to think about how to get that from the clues. $\endgroup$ Mar 24, 2020 at 16:18

I think the first image is

$\pi$. The image consists of a triangle ($3$ sides), a number ($14$), and a hexadecagon ($16$ sides). Putting them together gives $3,14,16$: the start of the decimal expansion of $\pi$.

The second image might be

$=$. It shows a balanced set of scales, both sides of equal weight.

The third image is probably

the one that gives two different characters in the solution, since there are clearly two different parts to this. 1000 might be interpreted in Roman numerals as $M$, or in prefix unit notation as $k$ (kilo).

The fourth image should be

$C$, because the image shows a sea.

Overall that gives

$\pi=RMC$ or $\pi=RkC$. This is five characters, but it doesn't make sense yet. Probably we need to do something else with ... my guess would be the third image.

  • $\begingroup$ This is not the correct answer but you're actually close though(except on the 1st image). Also, the only image representing 2 characters is image4("a letter and a number") $\endgroup$ Mar 24, 2020 at 15:20
