status is really about 2.5 - 2 for the elementary binomial theorem/formula, and 3 for the Newtonian. [[User:Anthony Argyriou|Anthony Argyriou]] 17:23, 18 July 2007 (CDT)

While the definition is strictly true, it seems written backwards, in that if you actually do
the sum for (x+y)^2 the answer you get as the equation is written is y^2 + 2xy + x^2. Of course you can rearrange
to get x^2 + 2xy + y^2.  Another way to write it would be
x^(n-k)y^(k), in which case you directly get the answers as shown in the examples.
