It’s photoshopped

If you zoom in, you can read what those abbreviations mean and it’s all different math expressions. So I guess it’s something else that just reminds people of a periodic table. Also the word “maths” can be read on the poster, so another indication that this is not a periodic table…

I hope it is, but the ‘R’ looks slightly out-of-place to me. It being simply off-center could just be due to the way it was made, but it also looks slightly rotated relative to the text below it, which seems unlikely. But maybe my eyes are playing tricks or there’s some other explanation.

If you zoom in, it’s clearly a “periodic table of math”. You see this sort of thing sometimes, where someone will make a chart composed of prominent objects, categories, or concepts in a field, arranged to look like the periodic table of chemical elements. Like the “periodic table of beer styles” or “periodic table of musical genres”, typically with abbreviations similar to chemical symbols.
This one has elements like “Decimal Point”, “Numerator”, “Cosine Rule”, “Rotation”, etc.

It does at least appear to group related topics. I dunno what to tell you, it looks like an elementary school classroom, I’m not sure they put that much thought into it.
The teacher who put it up knew, the camera guy knew, everybody knew.
Except you, you didn’t know this image is shopped.
If it is, I did not
