"Enigma"

Is this the correct name for a math symbol that represents the phrase, "There exists"? I believe it's something like an 'E'.

It's a backwards "E", and it's called the existential quantifier.
 
Yes, I've found a very useful website with this information.

Thank you for your time.

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
