For all my maths geeks out there!

What a neat way of applying the (x+y)^2 formula (x=57000, y=683).
This also reminded me what Malcolm Gladwell said in an interview. According to him, Chinese people are better in maths because we don´t waste time "translating the number from the word" (ie our word for eleven would be "ten and one"). Hence we could extrapolate this and say that Chinese people are always "block calculating"? Splitting 57683 into 57000+689? Interesting.
