I would like help solving this magic square. I can't find the pattern to it. And the symbols throw me off. The aim is to find the blank square in the bottom right corner.
And sorry if this is in the wrong section,

Thanks

Any reason why you're calling that a "magic square"?

Any background, like where is it from?
