This Plus Math icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,300 icons, all in the same style and quality.
This is a very simple icon that is meant to represent the plus sign used in addition. It's made of two lines of exactly the same size crossed over each other so that they run perpendicular. The lines are fairly thick.
