    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 IMAG0088.jpg
