SUMMARY

The discussion centers around a mathematical expression derived from a book by Lauren Child, which lacks proper formatting, specifically an equality sign. Participants identified a missing bracket in the expression and humorously noted that the solution to the equation is 42. The conversation highlights the importance of proper mathematical notation, as one participant emphasizes that an equation must include an equality sign to be valid. The mention of collaboration with mathematician Marcus de Sautoy adds credibility to the context of the discussion.

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...
 
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: =.

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
