"Shape Math™ is a brand-new patent pending technique

However good Shape Math™ is, as it stands this new section looks like it should be removed. There are no references and the text seems to be lifted from http://www.shapemath.com/Shape_Math/Shape_Math_Home_page.html . The ™ gives me the impression it's a commercial scheme; not a problem in itself, but there are no secondary sources for its use, even the Website that promotes it is not referenced. And the shape-work referred to seems to be virtual rather than physical. Please reply here if you have good reasons for it to remain. --Annielogue (talk) 07:12, 17 March 2012 (UTC)[reply]

Number line

The section on the number line has critical analysis not present in the other sections and seems to be one person's point of view. It should be rewritten, removed, or sourced. 99.37.203.12 (talk) 18:55, 9 January 2014 (UTC)[reply]
