[edit] Merging

The section Square number#Uses is about squaring numbers, so the definition of squares do not belongs here. Melchoir 12:34, 19 March 2006 (UTC)

I also think that something more about finding squares from other numbers can be useful here. To calculate the square of 27, for instance, all you need to do is multiply 4*30 and add 2 because (23-3)(2+3) + 19 = 127^2. It is clear that I do not know what I am talking about and that you shouldn't take my advice. I also wish that I had a brain. Even though I look up definitions of random mathematic laws, I still don't know how to add. Your website has not be useful to me because I still don't understand what a square truly is.Melchoir 12:34, 19 March 2006 (UTC)


Well, I've done the merge, as well as a bit in the other direction. If you'd like to expand on squares of integers, that material is accumulating at Square number, not here. Melchoir 11:32, 24 March 2006 (UTC)

[edit] Arithmetic/algebra

Square (algebra) but Cube (arithmetic). I'd prefer cube (algebra). googl t 21:31, 14 June 2006 (UTC)

[edit] Square of a vector

Should we perhaps note that the "square" of a vector as commonly denoted by \vec{x}^2 is usually understood to be |\vec{x}|^2? Shinobu 09:42, 13 November 2007 (UTC)
