Who knows this formula and its solution?

Mismatching brackets in the last sum. And I doubt the overall expression is well-defined.
Simply open the door and work from there without entering the room? ;)

yes, one bracket is missing. I found out where the equation is from, it is from a book by an author named Lauren Child, and using that information, I found out that the solution to the equation is 42. LOL! She cooperates with maths prof Marcus de Sautoy...

What the h**l is this and where's the equality sign?

Where is the equality sign in 3+5 (a "slightly" easier problem of the same type)?

What you have in the image is NOT an equation. An equation has this symbol in it somewhere: =.

, it is from a book by an author named Lauren Child, and using that information, I found out that the solution to the equation is 42. LOL! She cooperates with maths prof Marcus de Sautoy...

That would be the value of the expression (I didn't confirm this for myself, though).

Here is the formula in original version, straight from the book by Lauren Child
